well, clearly 4 > 1.
Answer:
f(x) has a greater slope.
Step-by-step explanation:
The slope of a function in the form of y=Mx+C is represented by the letter M, so the slope in the function F(x) =4.
Now when you have a function but you only have a table to evaluate it, to calculate the slope you have the next formula:
[tex]m=\frac{y^{2}- y^{1}}{x^{2} -x^{1} }[/tex]
You just have to pick two points from the table to use in the formula, we´ll use (4,7) as our point 1 and
(6,9) as our point 2.
This means that:
[tex]x^{1}=4[/tex] [tex]y^{1}=7[/tex]
[tex]x^{2}=6[/tex] [tex]y^{2}=9[/tex]
Now you just put it into the formula:
[tex]m=\frac{9-7}{6-4}[/tex]
[tex]m=\frac{2}{2}[/tex]
[tex]m=1[/tex]
Now that you have both slopes, you can see that the slope of g(x)=1 and the slope of f(x)=4, and you can see that f(x) has a greater slope thatn g(x).

A board 60 in. Long is cut two parts so that the longer piece is 5 times the shorter. What are the length of the two pieces?
Answer:
The shorter piece is 10 in. and the longer one is 50 in.
Step-by-step explanation:
First, let's set the shorter piece to be length x. Then the longer piece is 5x, or 5 times longer than the shorter piece.
Since both pieces combined equals to the length of the entire board, we can set these two lengths equal to it:
x + 5x = 60
And now solve for x:
6x = 60
x = 10 in (length of shorter piece)
Now let's find the length of the longer piece:
Longer = 5x = 5(10) = 50 in.

Answer:
(x - 7)(x - 8)
Step-by-step explanation:
To factorise the quadratic
Consider the factors of the constant term (+ 56) which sum to give the coefficient of the x- term (- 15)
The factors are - 7 and - 8, since
- 7 × - 8 = + 56 and - 7 - 8 = - 15, hence
x² - 15x + 56 = (x - 7)(x - 8)

which graph represents the given linear function 4x+2Y=3
Answer:
B
Step-by-step explanation:
4x + 2y = 3
(send 2y to the right and 3 to the left)
4x - 3 = -2y
(divide everything by -2)
(4x)/(-2) - 3/(-2) = y
So now we have a function which is like
y = ax + c
c = the y value of intersection point of the equation and the y-axis
a = amount of increase in y values per x value
so in this example:
(4x/(-2)) = (4/(-2))x -> a = 4/(-2) = -2
and
c = -3/-2 = 3/2
So the graph that we're searching for is increasing (-2) y values (so decreasing 2 y values) per 1 x value and has an intersection with the y-axis where y = 3/2
What’s the value of x
Answer:
25
Step-by-step explanation:
2x + 2 + 5x + 3 = 180
2 lines that cross make consecutive angles supplementary.
Combine the left.
7x + 5 = 180 Subtract 5 from both sides.
7x +5-5=180-5 Combine
7x = 175 Divide by 7
7x/7=175/7
x = 25
Triangle ABC is translated 2 units right and 5 units down to form triangle A′B′C′. This triangle is then translated 5 units right and 4 units up to form triangle A″B″C″. If vertex A is at (-4, 2), what are the coordinates of vertex A″? A. (3, -1) B. (3, 1) C. (-4, -2) D. (2, -4) E. (-11, 1)
Answer:
B
Step-by-step explanation:
So, for this problem, it is only asking for vertex A, so you only have to apply the transformations to one point (unless you want to find out where the other points are at).
Vertex A is at (-4,2).
The triangle is first translated 2 units right and 5 units down.
So to find the coordinate of that you have to understand that is you translate something right or left, the x value will change. And if it's up or down, the y value will change. If you are going right or up, the amount it's moved will be added. And left or down will be subtracted.
-4+2=-2 (so the new x-value will be -2)
2-5=-3 (so the new y-value will be -3)
Thus vertex A' is (-2,-3).
Now for the next transformation.
(-2,-3) is moved 5 units right and 4 units up.
-2+5=3 (so x-value will be 3)
-3+4=1 (so the y-value will be 1)
SO, the new coordinate of vertex A" is...
(3,1)! aka B
(Also, you can just illustrate this on a graph but i'm showing it to you this way because when you get more advanced the amount it is being translated will be much higher.)
Answer: The answer is B

If ABCDE is reflected over the x-axis and then translated 3 units left, what are the
new coordinates D?
are
HE
RE
When point D in shape ABCDE is reflected over the x-axis, the y-coordinate changes its sign. If it is then translated 3 units to the left, the x-coordinate of D decreases by 3. Therefore, if the original coordinates of D are (d1, d2), after these transformations, its new coordinates will be (d1-3, -d2).
Explanation:To answer this question, we need to understand how the reflection and translation transformations affect the coordinates of point D in the shape ABCDE.
First, when a point is reflected over the x-axis, the y-coordinate changes sign. For example, if the original coordinates of D are (d1, d2), after reflection over the x-axis, the new coordinates will be (d1, -d2).
Next, a translation of 3 units to the left (in the negative x direction), lowers the x coordinate by 3 units. Thus, after this translation, the final coordinates of point D will be (d1-3, -d2).
So, if you know the original coordinates of point D in the shape ABCDE, you can calculate its new position after these transformations in the described way.

The equation of the circle with center (3, -2) and radius 7 is:
Answer:
[tex](x-3)^{2}+(y+2)^{2}=49[/tex]
Step-by-step explanation:
The center-radius form of the equation of a circle is in the format;
[tex](x-h)^{2}+(y-k)^{2}=r^{2}[/tex]
with the center being at the point (h, k) and the radius being r units.
We simply plugin the values of the center and radius given in order to determine the equation of the circle;
The equation of the circle with center (3, -2) and radius 7 is;
[tex](x-3)^{2}+(y+2)^{2}=49[/tex]
Answer:
[tex](x-3)^2 + (y+2)^2 = 49[/tex]
Step-by-step explanation:
The general equation of a circle has the following form:
[tex](x-h)^2 + (y-k)^2 = r^2[/tex]
Where the point (h, k) represents the center of the circle and r represents the radius
In this case we know that the center is (3, -2) and the radius is 7.
Therefore:
[tex]h=3\\k = -2\\r=7[/tex]
Finally the equation of the circle is:
[tex](x-3)^2 + (y-(-2))^2 = 7^2[/tex]
[tex](x-3)^2 + (y+2)^2 = 49[/tex]
What is the inverse of the function f(x) = 4x + 8?
h(x) = x – 2
h(x) = x + 2
h(x) = x – 2
h(x) = x + 2
To find the inverse of an equation just switch the places of the x and y, then solve for y like so...
(keep in mind that f(x) means the same thing as y)
original equation:
y = 4x + 8
switching x and y:
x = 4y + 8
x - 8 = 4y
[tex]\frac{1}{4}x[/tex] - 2 = y

In simplest radical form, what are the solutions to the quadratic equation 6 = x2 – 10x?
Answer:
[tex]x = 5+\sqrt{31}\,\, and\,\, x=5-\sqrt{31}[/tex]
Step-by-step explanation:
We need to solve the quadratic equation
6 = x^2 -10x
Rearranging we get,
x^2-10x-6=0
Using quadratic formula to solve the quadratic equation
[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
a= 1, b =-10 and c=6
Putting values in the quadratic formula
[tex]x=\frac{-(-10)\pm\sqrt{(-10)^2-4(1)(-6)}}{2(1)}\\x=\frac{10\pm\sqrt{100+24}}{2}\\x=\frac{10\pm\sqrt{124}}{2}\\x=\frac{10\pm\sqrt{2*2*31}}{2}\\x=\frac{10\pm\sqrt{2^2*31}}{2}\\x=\frac{10\pm2\sqrt{31}}{2}\\x = 5\pm\sqrt{31}[/tex]
So, [tex]x=5+\sqrt{31}\,\, and\,\, x=5-\sqrt{31}[/tex]
Answer:
The solutions are:
x1= 5 +√31
x2= 5 -√31
Step-by-step explanation:
We have 6=x^2-10x
Balance the equation by adding the same constant to each side
x^2-10x+25=6+25
x^2-10x+25=31
Rewrite as perfect square,
(x-25)^2=31
Taking square root at both sides
√(x-5)^2 = √31
x-5 = (+/-)√31
x1= 5 +√31
x2= 5 -√31
Therefore the solutions are x1= 5 +√31 , x2= 5 -√31

Answer: The correct option is (B) 7.
Step-by-step explanation: Given that a karate studio charges $35 for the first course and $22.50 for each course after that, even if the student leaves the course early.
Cena paid $170 for her son to take courses.
We are to find the number of courses that he took.
Let x represents the number of courses that Cena took.
Then, according to the given information, we have
[tex]35+22.50\times (x-1)=170\\\\ \Rightarrow 22.50(x-1)=170-35\\\\ \Rightarrow 22.50(x-1)=135\\\\ \Rightarrow x-1=\dfrac{135}{22.50}\\\\\Rightarrow x-1=6\\\\ \Rightarrow x=7[/tex]
Thus, the required number of courses that Cena took is 7.
Option (B) is CORRECT.

For the right triangle shown, the lengths of two sides are given. Find the third side. Leave your answer in simplified, radical form.
a = 5, b = 10, c =
Answer:
5 sqrt(5) =c
Step-by-step explanation:
We can use the Pythagorean theorem to find the length of the hypotenuse
a^2 + b^2 = c^2 since this is a right triangle
5^2 + 10^2 = c^2
25+100 = c^2
125 = c^2
Take the square root of each side
sqrt(125) = sqrt(c^2)
sqrt(25*5) = c
sqrt(25) sqrt(5) = c
5 sqrt(5) =c
Alright, in a right-angled triangle, the lengths of the three sides are related by the Pythagorean Theorem, which states that the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
This can be written as:
c² = a² + b²
In the question you provided, you've given that side a is 5 and side b is 10, and you'd like to find side c, the hypotenuse.
Following the Pythagorean Theorem :
c² = a² + b² = 5² + 10² = 25 + 100 = 125
Now we need to find the length of side c by taking the square root of c²:
c = √125
This can be further simplified by recognizing that 125 is equal to 25 * 5, and the square root of 25 is 5.
c = √(25 * 5) = √25 * √5 = 5√5
Therefore, the length of side c in its simplified radical form is:
c = 5√5
That would be the value of the hypotenuse of the right triangle with side lengths 5 and 10.
