You will need to crest a graph first then place then variables
6(w+5) represents the product of 6 and the sum of w and 5. the product means multiplication, and the sum means addition.
6(w+5) also equals 6w+6(5), or 6w+30, because of the distribution property.
A, it's always positive because B(0) = 400
C, the population is growing. you can tell because the base is the rate of growth 1.4 > 1
Y= -7/5x + 4
To find -intercept/zero, substitute
Multiply both sides of the equation by
0= -7/5x +4
Move the variable to the left-hand side and change its sign
0= -7x +20
Divide both sides of the equation by
7x=20
20/7 = 2 6/7 = x 2.857
