Answer:
D
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) = (8, - 1), thus
y = a(x - 8)² - 1
To find a substitute (0, - 17), the coordinates of the y- intercept into the equation.
- 17 = a(0 - 8)² - 1
- 17 = 64a - 1 ( add 1 to both sides )
- 16 = 64a ( divide both sides by 64 )
a = 
= - 
y = - (x - 8)² - 1 → D
Answer:
<u><em>y = -(2/5)x+4</em></u>
Step-by-step explanation:
The 2 points are 0,4 and 5,2. If you want to find the equation, you need slope. slope = rise/run = -2/5.
y = mx + b. The b is the y intercept, so it's 4.
The equation is <u><em>y = -(2/5)x+4</em></u>
A two-step equation in a real world problem can be solved using these steps:-
- Identify the variables
- Write a equation
- Solve for the unknowns
- Answer the question and include units.
Answer:
The answer would be reflection.
Step-by-step explanation:
the answer is reflection because you would reflect it over the axis.
