Answer:
C. 2x +5y = -15
Step-by-step explanation:
You want the form ax +by = c. To get that form, you need to put the x-term on the left (making sure its sign is positive) and the constant on the right.
Multiply by 5:
5y +35 = -2(x -10)
Eliminate parentheses:
5y +35 = -2x +20
Add 2x-35
2x + 5y = -15 . . . . . . corresponds to selection C

Ms. Chloe has 5 cups of popcorn, which she is serving as a snack to a group of children. Each serving is 1/4 of a cup. How many children can get a serving of popcorn as a snack?
20 children can get a serving of popcorn
Since each serving is 1/4 of a cup, each cup can provide for 4 children. Since there are 5 total cups, multiplying 5 by 4 will give you 20.
The answer is 20 because first you have to set up a division equation. It would be 5 divided by 1/4.You can’t divid with a fraction so you must change it into a multiplication sentence. The new equation would now be 5 times 4/1 and the answer would be 20. Therefore, Ms.Chloe can freed 20 children.

What is arithmetic progression?A series of numbers called an arithmetic progression or arithmetic sequence has a constant difference between the terms. An arithmetic progression with a common difference of 2 is found, for instance, in the numbers 5, 7, 9, 11, 13, and 15.
Given
a = 6
d = 11-6 = 5
aₙ = a + (n-1)d
n = 5, 6, 7
a₅ = 6 + (5-1)5
a₅ = 6 +20 = 26
a₆ = 6 + (6-1)5
a₆ = 6 +25 = 31

The point-slope form of the equation of the line that passes through (-9, -2) and (1.3) is y-3=1/2(x-1). What is the slope-intercept form of the equation for this line?
Answer:
y = 1/2x + 5/2
Step-by-step explanation:
y-3=1/2(x-1).
To get from point slope to slope intercept, distribute the slope
y-3 = 1/2 x -1/2
Then add 3 to each side
y-3+3 =1/2 x -1/2 +3
y = 1/2x +2 1/2
Or if we want the last term as an improper fraction
y = 1/2x + 5/2
If 38 12-m – 82m, what is the value of m?
Answer:
[tex]m=-\frac{26}{83}[/tex]
Step-by-step explanation:
Since you are asking for the value of [tex]m[/tex], it is reasonable to assume that we are dealing with an equation here and you forgot to type the equal sign. Given that, I assume our equality is [tex]38=12-m-82m[/tex]. Let's solve it step-by-step:
Step 1. Subtract 12 from both sides of the equation
[tex]38-12=12-12-m-82m[/tex]
[tex]26=-m-82m[/tex]
Step 2. Combine like terms (m terms)
[tex]26=(-1-82)m[/tex]
[tex]26=-83m[/tex]
Step 3. Using the reflexive property of equality: if a = b, then b = a
[tex]26=-83m[/tex]
[tex]-83m=26[/tex]
Step 4. Divide both sides of the equation by -83
[tex]\frac{-83m}{-83} =\frac{26}{-83}[/tex]
[tex]m=-\frac{26}{83}[/tex]
We can conclude that the value of m is [tex]-\frac{26}{83}[/tex].

Write an equation for the nth term of the given geometric sequence. 12, 156, 2028, ..., a
Answer:
a(n) = 12 * (13)^(n-1)
Step-by-step explanation:
First step is to determine what's the scale/multiplication factor between each term:
156 / 12 = 13
2028 / 156 = 13
So, since we got 13 between 1st, 2nd and 3rd term, we can be confident it's the right multiplication factor.
an would be the first term (12) multiplied by a factor of 13. So,
[tex]an = 12 * (13)^{n-1}[/tex]
If we try for n > 1, we have
a(2) = 12 * (13)^(2-1) = 12 * 13 = 156
a(3) = 12 * (13)^(3-1) = 12 * 13² = 12 * 169 = 2028
It matches!

Here's a graph of a linear function. Write the equation that describes that function.
Answer:
[tex]f(x)=\frac{1}{4}x-4[/tex]
Step-by-step explanation:
To find the equation of a linear function , we pick two points from the graph
LEts pick two points (0,-4) and (4,-3)
Equation of linear function is [tex]f(x)=mx+b[/tex]
where m is the slope and b is the y intercept
[tex]slope = \frac{y_2-y_1}{x_2-x_1}[/tex]
(0,-4) is (x1,y1) and (4,-3) is (x2,y2)
[tex]slope m= \frac{y_2-y_1}{x_2-x_1}=\frac{-3+4}{4-0} =\frac{1}{4}[/tex]
y intercept is the point where the graph crosses y axis
y intercept [tex]b=-4[/tex]
Linear function becomes

Her revenue, or the amount she receives for selling n candles, can be represented by the function R = 4n. Which function represents Elsa’s profit, P, for selling n candles?Elsa makes and sells candles. The function C = 2n + 125 represents her costs, in dollars, for producing n candles. Her revenue, or the amount she receives for selling n candles, can be represented by the function R = 4n. Which function represents Elsa’s profit, P, for selling n candles?
ANSWER
P(n)=2n-125
EXPLANATION
Profit equals selling price minus cost price.
P(n)=R(n)-C(n)
The cost price is given by the function;
C(n)= 2n + 125
The selling price is represented by the function:
R(n)=4n
The function that represents the profit function is :
P(n)=4n-(2n+125)
Expand
P(n)=4n-2n-125
Simplify:
P(n)=2n-125
Answer:P = 2n – 125

The ratio of side lengths for two similar cubes is 2/5
Show your work or explain how you got your answers.
a.The perimeter of one face of the smaller cube compared to the perimeter of one face of the larger cube
Answer:
The perimeter of one face of the smaller cube compared to the perimeter of one face of the larger cube is [tex]\frac{2}{5}[/tex]
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor
and
If two figures are similar, then the ratio of its perimeters is equal to the scale factor
Let
z-----> the scale factor
x-----> the perimeter of the smaller cube
y ----> the perimeter of the larger cube
[tex]z=\frac{x}{y}[/tex]
in this problem we have
[tex]z=\frac{2}{5}[/tex] ----> scale factor

[tex]\frac{x}{y}=\frac{2}{5}[/tex]
What is the length of each side of the larger square
Answer:
The larger square is 6 cm on a side
Step-by-step explanation:
Let x = the side of square 1
Let y = side of square 2
A= s^2
Area of square 1 = x^2
Area of square 2 = y^2
The total area of both squares = x^2 +y^2 = 45
We know that y = 2x
Substituting in
x^2 + (2x)^2 = 45
x^2 +4x^2 = 45
5x^2 = 45
Divide each side by 5
5x^2/5 = 45/5
x^2 = 9
Take the square root of each side
sqrt(x^2) = sqrt(9)
x = 3
y = 2x = 2(3) = 6
The larger square is 6 cm on a side

Answer:
B. 1
Step-by-step explanation:
Your answer for A is correct.
The time it take for the sub to hit the water will be the time between when the submarine started to get lowered and when its distance from the water was zero.
The sub started to get lowered at x = 0.
Now we need to solve for the smallest positive zero of the function.
This function factors to (x - 1)(x - 7)
From this we can tell that the submarine is a water level for time x = 1 and x = 7.
The smallest of these is 1, so that is when the submarine first hit the water and 7 is when it came back out.
The sub started getting lowered at x = 0 and hit the water at x = 1 and because x is in seconds, it took 1 second for the sub to hit the water.

look at picture and plzz help answer is more than one option
Answer:
f(x) reflect over the x-axis, vertically stretch by a factor 3, and
shift down 1 unit ⇒ 2nd answer
Step-by-step explanation:
* To solve this problem you must to know some fact about
transformation
- If the function f(x) translated horizontally to the left
by h units, then the new function g(x) = f(x + h)
- If the function f(x) translated vertically up
by k units, then the new function g(x) = f(x) + k
- If the function f(x) translated vertically down
by k units, then the new function g(x) = f(x) – k
- A vertical stretching is the stretching of the graph away from
the x-axis
• if k > 1, the graph of y = k•f (x) is the graph of f (x) vertically
stretched by multiplying each of its y-coordinates by k.
- A vertical compression is the squeezing of the graph toward
the x-axis.
• if 0 < k < 1 (a fraction), the graph is f (x) vertically compressed
by multiplying each of its y-coordinates by k.
• if k should be negative, the vertical stretch or compress is
followed by a reflection across the x-axis.
* Now lets solve the problem
- From the graph
∵ The line passes through the points (0 , -1) and (-1 , 2)
∴ The slope of the line = (2 - -1)/(-1 - 0) = 3/-1 = -3
∵ The graph intersect the y-axis at point (0 , -1)
∵ The equation of any line ⇒ y = mx + c , where m is the slope
of the line and c is the y-intercept
∵ m = -3 and y-intercept = -1
∴ y = -3x - 1 ⇒ g(x) = -3x - 1
∵ f(x) = x
* From all the transformation above
# -3x means the graph reflected over the x-axis, vertically stretch
by a factor 3
# -1 means shift down 1 unit
# g(x) = -3f(x) - 1
∴ f(x) reflect over the x-axis, vertically stretch by a factor 3, and
shift down 1 unit
* The second answer
The length of a rectangle is 45 inches more than the width. The perimeter is 346 inches. Find the length and the width.
Solution:
Perimeter of Rectangle = 346Let Required length of breadth be x
Then, Length of Rectangle = 45 + xNow, We have ;
Perimeter of Rectangle = 2(l+b)Perimeter of Rectangle = 2 ( 45 + x + x346 = 2 ( 45 + 2x )346 = 90 + 4x 346 - 90 = 4x 256 = 4x x = 256 ÷ 4 x = 64 inchesSo, Length of Rectangle = x + 46
Length of Rectangle = 64 + 46
Length of Rectangle = 110 inches
Now, Breadth of Rectangle = 64 inches.
Answer:
Length = 109 inches and width = 64 inches
Step-by-step explanation:
Perimeter = 2(length + width)
Let the width of the rectangle be 'w' inches
Length of the rectangle would be = 45+w inches
2((45+w)+w) = 346
2(45+2w) = 346
90 + 4w = 346
4w = 346 - 90
4w = 256
w = [tex]\frac{256}{4}[/tex]
w = 64 inches
Length = 45 + 64 = 109 inches
Length = 109 inches and width = 64 inches

However, if we are ADDING instead of multiplying, then the correct number is 8, because 0 + 8 = 8.
If a line has a slope of 1/2 and a y-intercept of -6, what is the x-coordinate if the y-coordinate is 4
Answer:
X=20. Our x coordinate is 20.
Step-by-step explanation:
Based from the given slope of 1/2 and a y-intercept of -6, our equation of a line is y=x/2 -6. To remove the fraction we can multiply the equation by 2 to get 2y=x-12. Using this substitute the value of y coordinate 4.
2(4)= x-12
8+12 =x
X=20.
Answer:
20
Step-by-step explanation:
since the line has a slope of 1/2, the x coefficient of the line is 1/2. Since the y intercept is -6, we have the equation of the line
x/2 - 6 = y
Since in this case y = 4, we have
x/2 - 6 = 4
x/2 = 10
x = 20
So the x coordinate is 20 when the y coordinate is 4.
