Answer:

Step-by-step explanation:
we are given a point as
(-3,-5)
we know that any point can be represented as (x,y)
so, (x,y)=(-3,-5)
now, we can find x and y
we get


we know that any function can be represented as

It means when x=-3 , y=-5
so, we can plug these values

Answer:
h = 140
Step-by-step explanation:
To solve for h, we will have to get the equation into the form h = _. That would be our answer.
0.8h = 112
Divide 0.8 from both sides to get rid of the coefficient of 0.8 on the left side.
h = 112/0.8
Change 112/0.8 to 1120/8 on the right side. This will make the fraction easier to simplify.
h = 1120/8
Simplify the fraction on the right side.
h = 140/1
140/2 equals 140.
h = 140
