The function y = 4.99 +1.89(x + 5) can be used to determine the cost in dollars for a monthly gym membership for x months. What is the rate of change of the most in dollars with respect to the number of memberships purchased?

4 + 5 7/9= 9 7/9

step-by-step explanation:

x coordinate is none

step-by-step explanation:

1. a^4+8a^3+24a^2+32a+16

2.y^8+8y^7+28y^6+56y^5+70y^4+56y^3+28y^2+8y+1

3.x^6-3x^4y^2+3x^2y^4-y^6

the correct answer is b.

this is because an open circle means < or > & since the line goes left it is < -3.

the next one has a filled circle so it can only be ≥ or ≤ and since the line goes right from 1 it is ≥ 1

hope that
