Answer:
A
Step-by-step explanation:
I had the same question that was hard
Answer:
C
Step-by-step explanation:
B would be classified as an absolute value function.
Even though C looks like it is just a horizontal line, it is continuous in all directions and does not curve or slant like letter B. Letter B would also have a different slope.
Remember that linear functions are also not vertical lines.
To find what 86% of 40 is, first convert 86% to a decimal, then multiply that decimal by 40.
86% = 0.86
0.86 • 40 = 34.4
So 86% of 40 is 34.4.
Answer:
y = (x + 6)² - 5
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
here (h, k) = (- 6, - 5), thus
y = a(x + 6)² - 5
To find a substitute (- 8, 6) into the equation
6 = a(- 2)² - 5
6 = 4a - 5 ( add 5 to both sides )
11 = 4a ( divide both sides by 4 )
a = , thus
y = (x + 6)² - 5 ← in vertex form
