Step-by-step explanation:
Divide two on both sides to get rid of it and the make the equation in the form y = mx + c

y = 3/2x + 5
since both lines are parallel they must have the same gradient which is 3/2
y = 3/2x + c
All you have to do now is to replace x and y with (2, -5) to find c
x = 2
y = -5
-5 = 3/2 × 2 + c
-5 = 3 + c
c = -5-3
c = -8

1day=24 hours
10 days=240hours
60mins=1hr
30mins=1/2hr
total is 240hr+21hr+0.5hr=261.5hr
total is 261.5hr
So,
15/390 = 5/130 = 1/26
In decimal form, that is 0.03846153846...
we have

Convert to vertex form

we know that
the equation of a vertical parabola in vertex form is equal to

where
(h,k) is the vertex

Group terms that contain the same variable, and move the constant to the opposite side of the equation

Complete the square. Remember to balance the equation by adding the same constants to each side


Rewrite as perfect squares


the vertex is the point 
therefore
<u>the answer is </u>
The y-value of the vertex is
