Step-by-step explanation:
The slope-intercept form of an equation of a line:

- slope
- y-intercept

19) and 20) you have in other your question.
Given that equation modelling the height of the building is given by:
<span>h(t)=-4.92t^2+14.69t+575
plotting the equation (see the plot below)
The domain in all real numbers.
</span>Range: (h∈R: 196800h≤115317961)

There is no choice of integers

such that the left hand side is a rational number.
Would both of them just be 6?
12/2=6 since it said the centroid
Answer: 
Step-by-step explanation:
Move all terms to one side
Simplify
Split the second term
Factor out common terms in the first two terms, then in the last two terms.
Factor out the common term
