Answer:

Step-by-step explanation:
we know that
The standard equation of a horizontal parabola is equal to

where
(h,k) is the vertex
(h+p,k) is the focus
In this problem we have
(h,k)=(0,0) ----> vertex at origin
(h+p,k)=(-4,0)
so
h+p=-4
p=-4
substitute the values


C
D
Reason: their ratio is 1
Mark brainliest please
Yep, this is all correct!
-6/2 = y/4
y = (-6×4)/2
y = -24/2
y = -12
x was multiplied by 2
and y was also multiplied by 2
Answer:
-1/4
Step-by-step explanation:
4x - 15 = -16
4x = -1
x = -1/4
Answer: Therefore, Option 'A' is correct.
Step-By-Step explanation:
Since we have given that
Amount spent on equipment = $36
Amount spent on fees = $158
Amount spent on transportation = $59
Total amount spent by them is given by

Percent cost of equipment of the total amount is given by

Percent cost of fees of the total amount is given by

Percent cost of transportation of the total amount is given by

Hence, Percent cost of the total spent on each is
14%, 62%, 23%.
Therefore, Option 'A' is correct.
