I got 4x if that isn’t right I will check again
Answer: See below
Explanation:
8x + 14 = 10x - 10 (alt. exterior angle)
8x - 10x = -10 - 14
-2x = -24
x = -24/-2
x = 12
Now plug x = 12 in 10x - 10 to find the angle:
10(12) - 10 = 120 - 10 = 110 degree
Below are the steps to solving this problem.
Answer: The graph becomes narrower
<u>Step-by-step explanation:</u>
The vertex form of a quadratic equation is: y = a(x - h)² + k where
- |a| represents the vertical stretch if |a| > 1, vertical shrink if |a| < 1
- (h. k) represents the vertex
A vertical stretch means the curve gets narrower.
A vertical shrink/compression means the curve gets wider.
Hey there!
Your equation will be f(x) = (5x + 1) / 2. Now, you'll need to find the inverse.
In the equation, replace f(x) with y, then switch x and y. Now, solve for y in the new equation. What equals y will be your inverse equation.
f(x) = (5x + 1) / 2
x = (5y + 1) / 2
(x)*2 = (5y + 1 / 2)*2
2x = 5y + 1
–1 –1
(2x – 1) / 5 = (5y) / 5
(2x – 1) / 5 = y
Your inverse function is f–1(x) = (2x – 1) / 5. Now, just plug in 8 for x and solve for the answer.
f–1(x) = (2x – 1) / 5
f–1(8) = (2(8) – 1) / 5
f–1(8) = (16 – 1) / 5
f–1(8) = 15 / 5
f–1(8) = 3
Your final answer will be 3. Hope this helped you out! :-)
