The answer is 57 because 8^1 is 8
The correct answer is 19, not 21
Answer/Step-by-step explanation:
<u>Steps to solve: 2/9 − (−1/3 ÷ 3/5)</u>
(-1/3 ÷ 3/5)
= (-1/3 x 5/3)
= (-5/9)
-2/9 - (-5/9)
= -2/9 + 5/9
= 3/9
<u>To check:</u>
5/9 - 2/9 = 3/9
Answer:
f(x) = (x - (-5))^2 + (-18)
Step-by-step explanation:
Given:
f(x) = x^2 + 10x + 7
Rewrite f(x) in vertex form
Solution:
f(x) = ax^2 + bx + c is a quadratic function.
The vertex form of f(x) is a(x - h)^2 + k, where (h, k) is the vertex.
=> f(x) = x^2 + 10x + 7
= x^2 + 10x + 25 - 18
= (x + 5)^ - 18
= (x - (-5))^2 + (-18)
=> f(x) can be rewritten in form of a(x - h)^2 + k, where (h, k) is the vertex, with a = 1, h = -5, k = -18
