Answer:
9x+7y+13
Step-by-step explanation:
add all the x's, y's, and no exponents together
First we do what’s in the parentheses.
7 • 10 - 5 = 70 - 5 = 65
Then we do exponents. We don’t have any so we skip this step.
Then we do multiplication and division.
65 • 0.0007 = 0.0455
We don’t have any addition or subtraction so we skip this step.
The solution is 0.0455.
If your quadratic function has x intercepts of 4 and -3, that means that the points are (4, 0) and (-3,0), or the values x has when y=0. Since your quadratic (which represents y) must then equal 0, then your factors of that equation would potentially equal 0 as well. That means that if x=4, then subtract 4 from each side to get x-4=0, and so one factor is (x-4) Similarly your other factor would be (x+3).
