Answer:
(2x +3 )(x-5)
one is the length and one is the width
Step-by-step explanation:
2x^2-7x-15
Factor
(2x )(x )
What are the factors of -15? -1*15 and -3*5, 3*-5 , 1*-15
We need 2* one factor ± the other factor = -7
2*-5 +3 = -7
That means the -5 is on the outside and the +3 is on the inside
(2x +3 )(x-5)
Answer:
80
Step-by-step explanation:
Insert the values or x and y into the expression.
= = 80
He saved 50 percent of his money
The correct answer is B. The function has a constant rate of change, decreasing for all x at a rate of 6.
In order to find the rate of change, we have to identify the slope. The slope is always the coefficient of x when in slope intercept form. In this case it is -6, which means it decreases at a rate of 6.
