Answer:
is there more to the problem
Answer:
see explanation
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:
6 Miles and the cost is $4.50
Step-by-step explanation:
3+0.25=0.75x
3+0.50x
6=x
0.75x+?
0.75 x 6= 4.50
Answer:
79 is the value
Step-by-step explanation:
Since both terms are perfect squares, factor using the difference of squares formula, a^
2 − b
^2 = (
a + b) (
a
−
b
) where a = t
^2 and b = 4
.
Answer: (
t^
2 + 4
) ( t + 2
) ( t − 2
)
