Answer:
x can be 4.99 to make y>0
Step-by-step explanation:
y= −1.5x + 7.5
For what value(s) of x is: y>0
lets solve for x first:
-1.5x + 7.5 = 0
-1.5x * 10 + 7.5 * 10 = 0 * 10
-15x + 75 = 0
-15x + 75 - 75 = 0 - 75
-15x = -75
x = -75/-15
x = 5
to make y>0, we substitute x<5 into the formula
y > −1.5(4.99) + 7.5
y > 0.15
therefore, x can be 4.99 to make y>0
