Given:
The function for size of a square frame is
[tex]f(x)=x+2[/tex]
where, x is the side length of the picture.
The function for the price in dollars for the frame is
[tex]p(x)=3x[/tex]
To find:
The single function for the price of a picture with an edge length of x.
Solution:
We know that, for a picture with an edge length of x.
Size of a square frame = f(x)
Price in dollars for the frame = p(x)
Single function for the price of a picture with an edge length of x is
[tex](p\circ f)(x)=p(f(x))[/tex]
[tex](p\circ f)(x)=p(x+2)[/tex] [tex][\because f(x)=x+2][/tex]
[tex](p\circ f)(x)=3(x+2)[/tex] [tex][\because p(x)=3x][/tex]
Let the name of this function is c(x). So,
[tex]c(x)=3(x+2)[/tex]
Therefore, the required function is [tex]c(x)=3(x+2)[/tex].

HELP ME HELP ME please !!! 10 points
Answer:
The slope is [tex]\frac{3}{2}[/tex]
The y-intercept is 9
Step-by-step explanation:
The form of the equation that passes through two points (x1, y1) and (x2, y2) is y = m x + b, where
m is the slope of the line whose rule is [tex]m=\frac{y2-y1}{x2-x1}[/tex] b is the y-intercept, you can find it by substituting x, y in the equation by (x1, y1) OR (x2, y2)Let us solve the question:
Choose any two-point from the table
∵ The line passes through the points (2, 12) and (4, 15)
∴ x1 = 2 and x2 = 4
∴ y1 = 12 and y2 = 15
→ Use the rule of m to find it
∵ [tex]m=\frac{15-12}{4-2}=\frac{3}{2}[/tex]
∴ m = [tex]\frac{3}{2}[/tex]
∴ The slope is [tex]\frac{3}{2}[/tex]
→ Substitute its value in the form of the equation above
∴ y = [tex]\frac{3}{2}[/tex] x + b
→ To find b substitute x and y by x1 and y1
∴ 12 = [tex]\frac{3}{2}[/tex] (2) + b
∴ 12 = 3 + b
→ Subtract 3 from both sides
∴ 12 -3 = 3 - 3 + b
∴ 9 = b
∴ The y-intercept is 9

Answer:
Check description
Step-by-step explanation:
First: work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100. % increase = Increase ÷ Original Number × 100. If your answer is a negative number, then this is a percentage decrease.
How do you solve this?
Answer:
145
Step-by-step explanation:
180-137=43
43+102=145
Answer The answer is 145 because, as you see you need a 180 degree angle, so you have 137 and you need to make those two angles 180 so 180-137=43 so then you got 43+102 so that's 145 then you have that other angle so that'll be 35, so the ? mark will be 145 since that 180-35

what does i2x + 3(x - 5) = 20 equal
Answer:
x=7
Step-by-step explanation:
2x+3(x-5)=20
2x+3x-15=20
5x-15=20
5x=35
x=7
Answer:
x = 5
Step-by-step explanation:
2x + 3(x - 5) = 20
simplify
5x - 5 = 20
get the variable and the number on different sides
5x - 5 + 5 = 5x
20 + 5 = 25
5x = 25
now divide each side by 5
5x / 5 = x
25 / 5 = 5
x = 5

Given the two functions below, tell me what type of graphs they are and
how p(x) differs from g(x)
p(x)=8x^2
g(x) = x^2
Answer:
Step-by-step explanation:
p(x) = 8x^2 is an increasing exponential curbed graph which starts from quadrant 2 , passes through the point (0, 8) on the y axis and rises steeply to the right.
g(x) = x^2 is a parabola ( shaped like a U) which has a minimum value at (0, 0).
and opens upwards either side of the y-axis. This type of curve is called a parabola.

The first and last buttons are 15 inches apart when measured from the top of the first button to the top of the last button. What is the distance, in inches, between the top two buttons on his shirt, from the top of one to the top of the other? (there are 5 buttons btw)
It should be 3 inches, but I am not sure what the length is of each button if i should subtract it or not.. otherwise it should be 3!!
What is the length of segment BC?
The length is 10 because this is a right triangle and based on the pythagorean theorem, the sum of the squares of the legs equals the square of the longest side.
6 squared plus 8 squared is 100, which is 10 squared.
The answer is 10.
Answer:
C. 10
Step-by-step explanation:
The Pythagorean Theorem states that a² + b² = c²
a² can be found by multiplying 6 by 6, which is 36
b² can be found by multiplying 8 by 8, which is 64
36 + 64 = 100.
The square root of 100 is 10, you can double-check this because 10 x 10 = 100
Because of this, we know that the line segment BC is equal to 10

SAT Prep) In the figure, what is the value of x? A. 30° B. 50° C. 15° D. 20°
Answer:
D. 20° Can I get brainliest please :)
Step-by-step explanation:
You can see their is a 90° angle, and angles across from each other are equal so them together is 180° and you know the whole thing is 360° so you can do
360°-180°=180°
then you have the x's we still know that angles opposite each other are the same so if we add all those angles together we get
x+x+2x+30°+2x+30°
simplify it
6x+60°
then we know what we have left is 180° so we do numbers to numbers
180°-60°=120°
now we have
6x=120°
simplify it
x=20°
The value of x is 20°. Option b is correct.
Value of angle x is to be determine.
it can be defined as the measure of one line tilt over other line.
Here, the sum of angle is 180°
x+90+2x+30=180
3x =180-120
3x = 60
x = 20
Thus, the value of x is 20°.

Solve the equation algebraically |x|=12
Answer:
x = 12
Step-by-step explanation:
Absolute value is the distance between the number and 0. Since distance cannot be negative, the absolute value of something is always going to be positive. In this equation | x | = 12 since 12 is already a postive number and the distance between 12 and 0 is 12, this means that x is equal to 12.

Solve 5ax + 3ax = 4ax + 12 for x. Assume a ≠ 0.
Answer:
c. 3/a
Step-by-step explanation:
5ax + 3ax = 4xa+ 12, combine like terms
8ax = 4ax + 12, minus 4ax on both sides
4ax = 12, divide 4a on both sides
youll be left with x = 3/a

x ^ 2–2x + 1
by splitting this equation
x ^ 2 - x -x + 1
there are a two terms x ^ 2 - x and - x + 1
we take x is common from first and -1 is common from second
x ( x - 1 ) and -1 ( x-1 )
the quadratic roots are (x-1) and (x-1)
x - 1 = 0
x = 1 in both
Therefore , the quadratic roots are 1 , 1 .

What is the slope?
Answer:
The slope is -1/5 and the y intercept is 12
Step-by-step explanation:
Y=-1/5x+12
This is in the form
y=mx+b where m is the slope and b is the y intercept
The slope is -1/5 and the y intercept is 12
Answer:
-1/5 = slope
12 = y-intercept
Step-by-step explanation:
y = mx + b
m is always equal to the slope
b is equal to the y-intercept
which makes -1/5 the slope
and makes 12 the y-intercept
