Answer:
The y-intercept is (0,-12).
Step-by-step explanation:
Given equation is 
.
Now question says to find the y-intercept of the given parabola .
We know that y-intercept means the y-value when x-value equals 0
so let's plug x=0 into given equation then solve that for y.
Hence the y-intercept is (0,-12).
Answer:
(r + 20)t = r
Step-by-step explanation:
Distance is constant in the scenario above, distance from home to wedding and wedding back home is the same.
From wedding back home. :
Recall : Distance = speed * time
Distance = r * 1 hour
From home to wedding :
Speed = 20 mph more ; r + 20
Time = t
Distance = (r + 20)* t = (r +20)t
Since the distance are the same, we can equate both :
(r + 20)t = r * 1
= (r + 20)t = r

When you are doing distributive property, it can only happen if a number or exponent is before the bracket. From this equation, you can solve for x like so:
7(x+5)-x=42
7x+35-x=42 -Using distributive property (Multiplication)
6x=7 -Collecting like terms.
x= 7/6 -The answer.
Therefore x would equate to 7/6.
