Answer:

7. D:61

8. A:57

9. A: 47

Step-by-step explanation:

Quesiton 7:

To find perimeter we add all the sides together.

x+2x+2x+5=145

Combine all the x's.

5x+5=145

To isolate the constants, subtract 5 from both sides.

5x=140

Now divide both sides by 5 to isolate the x.

x=28

The questions asks for the length of AC, so to find that we need to insert our new x.

AC= 2(28)+5

56+5=61

tatuchka [14]

Answer:

Answer:  D) 3.75

Step-by-step explanation:

According to the Insersecting chords theorem, when you multiply the lengths of the segments of one of the chords in a circle, the product obtained is equal to the product of the segments of the other chord.

Based on this, you can find the value of "x" with:

Solve for "x" (Applying the Division property of equality, you can divide both sides of the equation by 4). Then:

This value matches with the option D.

Given f(x) = x2 + 4x − 1 and g(x) = 5x − 7, identify (fg)(x).
8_murik_8 [283]
<span> f(x) = x^2 + 4x − 1 and g(x) = 5x − 7
</span>(fg)(x) =  (x^2 + 4x − 1)(5x − 7)
(fg)(x) = 5x^3 + 20x^2 - 5x - 7x^2 - 28x + 7
(fg)(x) =  5x^3 + 13x^2 - 33x + 7

answer is C. third choice

(fg)(x) =  5x^3 + 13x^2 - 33x + 7

Which function is the inverse of f(x) = 2x+37
WINSTONCH [101]

Answer:

f^{-1} (x)=\frac{x-3}{2}

Step-by-step explanation:

y = f(x)

y = 2x+3

You need to switch the places of x and y, into this:

x = 2y + 3

Then solve for y:

2y = x-3

y=\frac{x-3}{2}

f^{-1} (x)=\frac{x-3}{2}
