Step-by-step explanation:
The equation of a parabola in vertex form is
y = (x - h)² + k (h, k) are the coordinates of the vertex
Given y = x² + 7x - 5
To express in vertex form use the method of completing the square
add/subtract ( half the coefficient of the x- term )²
y = x² + 2( 
)x +
- - 5
y = (x + )² - - 
y = (x + )² - 
Hence
a = and b = -
Answer:
x=4 y=6
Step-by-step explanation:
The answer is D. Because the deeper you go in the ocean the colder it gets, and it also gets higher salinity.
Answer:
Step-by-step explanation:
A: $0.1(x) + 25(y) = x + 25
B: $0.05(x) + $40(y) = x + 40
Because they didn't give a certain amount of miles traveled, we have to go with we do know.
**this is probably wrong.
