If the system of the linear equations above has infinitely many solutions, and c is a constant, what is the value of c?
A) - 6
B) - 3
C) - 2
D) - 1
Answers
1. For the system of linear equations to have an infinite number of solutions, the two lines must cross over an infinite number of times, ie. they would be the same line.
Now, if they are the same line and we were to write out both equations in the form y = mx + c, this would mean that the m value (the gradient) and the c value (the y-intercept) would be the same. Thus, the first step is to write out both equations in the form y = mx + c.
a) Equation 1:
3x - 9y = -6
3x = -6 + 9y (Add 9y to both sides)
3x + 6 = 9y (Add 6 to both sides)
(1/3)x + 2/3 = y (Divide both sides by 9)
Thus, the first equation may be written as y = (1/3)x + 2/3
b) Equation 2:
(1/2)x - (3/2)y = c
(1/2)x = c + (3/2)y (Add (3/2)y to both sides)
(1/2)x - c = (3/2)y (Subtract c from both sides)
(1/3)x - (2/3)c = y (Multiply both sides by 2/3)
Thus, the second equation may be written as y = (1/3)x - (2/3)c.
2. Now that we have both equations in the form y = mx + c, we can look at their gradients and y-intercepts:
Equation 1: gradient = 1/3, y-intercept = 2/3
Equation 2: gradient = 1/3, y-intercept = -(2/3)c
As we can see above, the gradients of the two lines are the same, however for them to be the same line their y-intercepts must also be equal. Thus, we must equate the two y-intercepts to find c:
2/3 = -(2/3)c
1 = -c (Multiply both sides by 3/2)
-1 = c (Multiply both sides by -1)
Thus, if the system of linear equations has infinitely many solutions, and c is a constant, the value of c is -1 (answer D).
The value of 'c' for the given system of the linear equations with infinitely many solutions is - 1.
What is a linear equation?"A linear equation is an equation in which the highest power of the variable is always 1."

Match each function with the corresponding function formula when h(x) = 2 – 2x and g(x) = –2 x + 2.
Answers
Answer:
1 -> f
2 -> a
3 -> d
4 -> b
5 -> e
6 -> c
Step-by-step explanation:
We are given:
h(x) = 2 - 2x and g(x) = -2^x+2
a) k(x)= (g-h)(x) = g(x) - h(x)
= -2^x+2 - (2 - 2x)
= -2^x+2 - 2 + 2x
= -2^x+2x or 2x-2^x
k(x) = 2x-2^x = (g-h)(x)
So, 2 matches with a
b) k(x)= (g+h)(x) = g(x) + h(x)
= -2^x+2 + (2 - 2x)
= -2^x+2 + 2 - 2x
= -2^x+4-2x or 4 - 2^x -2x
So, k(x) = 4 - 2^x -2x = (g+h)(x)
So, 4 matches with b
c) k(x)= (2h - 2g)(x) = 2h(x) - 2g(x)
= 2(2 - 2x)-2(-2^x+2)
= 4 - 4x+2.2^x-4
= -4x+2^x+1 or 2^x+1-4x
So, k(x) = 2^x+1-4x = (2h - 2g)(x)
So, 6 matches with c
d) k(x) = (h-2g)(x) = h(x) - 2g(x)
= (2 - 2x)-2(-2^x+2)
= 2 - 2x+2.2^x-4
= -2-2x+2^x+1
= 2^x+1-2x-2
So, k(x) = 2^x+1-2x-2 = (h-2g)(x)
So, 3 matches with d
e) k(x) = (h-g)(x) = h(x) - g(x)
= (2 - 2x)-(-2^x+2)
= 2 - 2x+2^x-2
= -2x+2^x or 2^x-2x
So, k(x) = 2^x-2x = (h-g)(x)
So, 5 matches with e
f) k(x) = (2g+h)(x) = 2g(x)+h(x)
= 2(-2^x+2) + (2 - 2x)
= -2.2^x+4 + 2 - 2x
= -2^x+1+6-2x or 6 - 2^x+1-2x
So, k(x) = 6 - 2^x+1-2x = (2g+h)(x)
So, 1 matches with f
Final answer:
The function formulas are h(x) = 2 - 2x and g(x) = -2x + 2.
Explanation:
h(x) = 2 - 2x
g(x) = -2x + 2

What is reflection of line? What is the general equation of a straight line? What is triangle? What are parallel lines?A reflection over line is a transformation in which each point of the original figure (the pre-image) has an image that is the same distance from the reflection line as the original point, but is on the opposite side of the line The general equation of a straight line is : y = mx + cwhere : [m] → is slope of line and [c] → is the y - intercept
A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically : ∠x + ∠y + ∠z = 180°. There are different types of triangles such as : equilateral triangle , scalene triangle , isosceles triangle etc.Parallel lines are those lines that are equidistant from each other and never meet, no matter how much they may be extended in either directions. These lines have same slope.We have the some sub - questions given in question.
We will solve part [1].
We have -
y = - 5x - 8
Shifting down by 2 units, we get -
y = - 5x - 8 - 2
y = - 5x - 10
Reflection over the [x] axis, would be -
g(x) = - y
g(x) = - (- 5x - 10)
g(x) = 5x + 10
Therefore, the function y = f(x), when shifted down by 2 units and then reflected over the x-axis will become g(x) = 5x + 10.

A teacher asked her students how many pets they own. Here are the results:
Answers
Answer:
B.
Step-by-step explanation:
Basically, to draw a dot plot, what you do is place one circle above the corresponding value on the number line for each value in the data set, ie. if there is a 0 in the data set, then you would draw one 'dot' above 0 on the number line. If there was another 0, then you would draw another dot above the dot you drew for the first 0, and so on.
The data set given is:
0, 0, 0, 1, 1, 1, 1, 2, 2, 2, 3, 3, 4, 4, 8
If we count the number of each value, then we can say that:
a) there are three 0's
b) there are four 1's
c) there are three 2's
d) there are two 3's
e) there are two 4's
f) there is one 8
Now you could draw this up on a dot plot and compare this with the answers, or you could technically also just look at the dot plots in the multiple choice answers and count each of the values to see which one matches up with the values we defined above. So:
A. There are three 0's (correct), four 1's (correct), three 2's (correct), but there are no 3's - therefor this is not the correct dot plot.
B. There are three 0's (correct), four 1's (correct), three 2's (correct), two 3's (correct), two 4's (correct) and one 8 (correct) - therefor this is the correct dot plot.
We could use the same method to check if C and D were correct; then we would see that C only has two 0's and one 3 and is thus incorrect, and D only has one 3 and one 4, and has an extra value of 5, thus it is also incorrect.
Therefor, the answer is B.
Whilst this method may be used, a quick sketch of the dot plot may be a little easier to work with to compare visually with the answers, however everyone has their own way so try both methods and see what works for you.
''Option B'' shows the correct dot plot.
We have to given that,
A teacher asked her students how many pets they own.
Here are the results:
0,0,0,1,1,1,1,2,2,2,3,3,4,4,4,8
Now, From the data set,
0 is repeat 3 times.
1 is repeat 4 times.
2 is repeat 3 times
3 is repeat 2 times.
4 is repeat 3 times
8 is repeat only 1 times.
Hence, Option B shows the correct dot plot.

Given the graph below state whether or not the relation is a function, and give the domain and
range.
Answers
Answer:
NOT a functiondomain: [-2, 2]range: [-4, 4]Step-by-step explanation:
A vertical line intersects the graph twice, so the relation is not a function. It is only allowed to intersect once if the relation is a function.
The domain is the horizontal extent, which is from -2 to +2.
The range is the vertical extent, which is -4 to +4.
The relation is indeed a function, and its domain is [-2, ∞), and its range is (-∞, ∞), as you assumed. The verification process aligns with your initial statements.
If the assumed domain is [-2, ∞) and the assumed range is (-∞, ∞), it suggests that you believe the relation is a function that is defined for all real numbers and can output any real number.
To determine whether the relation is indeed a function, we need to check whether each input (x-value) corresponds to a unique output (y-value) and ensure it satisfies the vertical line test. Let's proceed with the verification:
Function Test (Vertical Line Test):Trace a vertical line through the entire graph. If the vertical line intersects the graph at only one point for each x-value, then the relation is a function. If the vertical line intersects the graph at more than one point for any x-value, then the relation is not a function.
Based on the assumed domain and range, it appears that you are considering the relation to be a function defined for all real numbers. In such a case, the relation would be a function by definition, as it assigns a unique y-value to each x-value.

Answer:
Here's what I get.
Step-by-step explanation:
Part A. Equation in standard form
The question is asking you to find the equation of a straight line that passes through two points
Let x = the number of days
and y = the cost
Then the coordinates of the two points are (2,225) and (5,480).
(i) Calculate the slope of the line
[tex]\begin{array}{rcl}m & = & \dfrac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\& = & \dfrac{480 - 225}{5 - 2}\\\\& = & \dfrac{255}{3}\\\\& = & 85\\\end{array}[/tex]
In other words, the daily rental is $85/day.
(ii) Calculate the y-intercept
[tex]\begin{array}{rcl}y & = & mx + b\\480 & = & 85 \times 5 + b\\480 & = & 425 + b\\b & = & 55\\\end{array}[/tex]
(iii) Write the equation for the line
y = 85x + 55
That is, the cost is $55 plus $85/day
Part B. Equation in function notation
Replace y with ƒ(x)
ƒ(x) = 85x + 55
Part C. Graphing
Let's say you want to plot a graph of the rental cost for up to ten days.
(i) Calculate two points on the graph.
When x = 0, y = 85; when x = 10, y = 905.
(ii) Scale your axes
A good number of intervals is about ten.
Your x-axis should have tick marks at 1-day intervals.
Your largest y-value is 905. Ten intervals would make about $90/interval. However, you should round that up to $100/interval for easy interpolation.
Your y-axis will run from 0 to $1000 in $100 intervals.
Plot your two points and draw a straight line through them.
(iii) Axis labels
x represents the number of days, so the label on the x-axis could be "No. of days."
y represents the cost of renting the boat, so the label on the y-axis could be "Rental cost."
Your graph should resemble the one below.

Step-by-step explanation:
We need to multiply the following terms using vertical multiplication method
3x^2-5x+1
x x^2+2x+4
The vertical multiplication is shown in the figure attached.
The result is: 3x^4+x^3+3x^2-18x+4
So, Option C is correct.
The vertical method of multiplication involves multiplying each digit of one number by each digit of another, one at a time, recording partial results and adding them together for the final result.
Explanation:To perform multiplication using a vertical method, first write the numbers vertically aligning them properly. We will be multiplying like this:
123 (number 1) x456 (number 2)
Start from the rightmost digit of the second number (bottom number) and multiply it with each digit of the first number (top number), advancing from right to left. Record each result underneath, shifted appropriately (similar to 'carry digits' in addition). After fully multiplying by one digit, proceed to the next digit in the second number, remembering to shift your results accordingly. Finally, add all the results together to get the final answer. This is the vertical method of multiplication.

Factor the polynomial, if possible. If the polynomial cannot be factored, write prime. 9n^3 + 27n^2 – 25n – 75
Answers
Answer:
(x+3)(3x-5)(3x+5)
Step-by-step explanation:
Let's consider the possible rational zeros: factors of -75 over factors of 9
So one such possible 0 is -3
let's try it and see if it works:
-3 | 9 27 -25 -75
| -27 0 75
------------------------------------------
9 0 -25 0
So x+3 is a factor and we have another there which is 9x^2+0x-25 or 9x^2-25
So far we have this as the factored form (x+3)(9x^2-25)
The second factor is a difference of squares so we can factored this more:
(x+3)(3x-5)(3x+5)
--------You could have also done factored by grouping here:
9x^3+27x^2-25x-75
(9x^3+27x^2)+(-25x-75)
9x^2(x+3)+-25(x+3)
(x+3)(9x^2-25)
(x+3)(3x-5)(3x+5)
Answer:
Step-by-step explanation:
9n^3 + 27n^2 – 25n – 75=9n²(n+3)-25(n+3)
= (n+3)(9n²- 25)
but : 9n²- 25 = (3n)² - 5²
by identity : a²-b² =(a-b)(a+b)
now : a =3n and b = 5 you have : 9n²- 25 = (3n)² - 5² = (3n-5)(3n+5)
Factor the polynomial :
9n^3 + 27n^2 – 25n – 75=(n+3)(3n-5)(3n+5)

Solve the equation.
42x – 5 = 64
Answers
Answer:
23/14
Step-by-step explanation:
42x - 5 = 64
Add 5 to both sides in order to isolate 42x
42x = 64 + 5
42x = 69
Divide 42 from both sides in order to isolate x
x = 69/42
The answer gives an uneven decimal so it'd be best to leave it as a simplified fraction. The simplified fraction is 23/14.
Answer:
x = 1.64
Step-by-step explanation:
42x – 5 = 64
add 5 to both sides
42x - 5 + 5 = 64 + 5
42x = 69
divide via by 42
x = 69/42
x = 1.64

You have been asked to select a marble from a bag that contains 3 blue marbles and
4 red marbles and flip a coin for heads or tails.How many possible outcomes are there in this sample space?
Answers
14 different outcomes.
3 blue + 4 red = 7 different marbles you could draw total.
since you have heads or tails possible with each of the 7, you multiply by 2(heads & tails)
7x3=14
Follow below steps:
When selecting a marble from a bag and flipping a coin, we are combining two separate actions that result in a compound event. The number of possible outcomes in the sample space can be calculated by multiplying the number of outcomes for each action. Since there are 3 blue marbles and 4 red marbles, there are 3 + 4 = 7 possible outcomes for drawing a marble. For flipping a coin, there are 2 possible outcomes: Heads (H) or Tails (T). To find the total number of possible outcomes for the combined actions, we multiply the outcomes for drawing a marble by the outcomes for flipping a coin: 7 (marble outcomes) times 2 (coin outcomes) = 14 possible outcomes in the sample space.
