Therefore, the inverse of f(x)=-8x+4 is (4-x)/8
What is mathematic expression?
A mathematical expression is defined as the collection of the numbersvariables and functions by using signs like addition, subtraction, multiplication, and division.
here, the function given is f(x) = -8x+4
and to find its inverse we replace f(x) = x and x = f(x) and solving for f(x) we get :
f(x) = -8x+4
x = -8f(x) +4
8f(x) = 4-x
f(x) = (4-x)/8
Therefore, the inverse of f(x)=-8x+4 is (4-x)/8

To find the inverse of f(x) = -8x + 4,
1) replace "f(x)" with "Y:" y = -8x + 4
2) interchange x and y: x = -8y + 4
3) solve this result for y: -8y = x - 4, or y = (x - 4)/(-8)
-1
4) replace this "y" with f (x): ":
-1 x - 4
f (x) = - ----------
8
One correct answer is:
2/8 green, 1/8 red, and 1/8 blue.
Explanation:
If there are 8 tiles, coloring 4/8 means coloring 4 tiles. Using those three colors, we could use each 1 time with 1 left over. Since we must have more green, we would use it twice; this would give us 2 green, 1 red and 1 blue.
Since the grid is not necessarily 8 squares, we must account for this by saying 2/8 green, 1/8 red and 1/8 blue.

Point B of the Triangle = ( x+2)
Point C of the Triangle = ( 6x+10)
(a) What is the value of x? Show your work.
(b) What is the measure of angle C? Show your work.
The 3 inside angles of a triangle need to equal 180 degrees.
Add the 3 angles together to equal 180:
X + x+2 + 6x +10 = 180
Simplify:
8x + 12 = 180
Subtract 12 from each side:
8x = 168
Divide each side by 8:
x = 168 / 8
X = 21
a) x = 21
b) C = 6x+10
replace x with 21:
6(21) + 10 =
126 +10 = 136
Answer:
x = 21 and C = 136°.
Step-by-step explanation:
(a) Sum of all the triangle = 180°.
∠A + ∠B + ∠C = 180°.
∠A= X, ∠B = x +2 , ∠C = 6x+10.
X + x + 2 + 6x + 10 = 180°.
8x + 12 = 180°.
8x = 168.
x = 21.
(b) The measure of angle C can be done by substituting the vale of x = 21.
6x + 10, x= 21.
=6 × 21 + 10
=136°.
Thus, the value of x = 21 and C = 136°.
