(03.01 LC) Given that h(x) = 3x −19, find the value of x that makes h(x) = 71. (5 points)
LekaFEV [45]
The function given is:
h(x) = 3x-19
we want to find the value of x that makes this function equal to 71. To do so, we will substitute h(x) with 71 and solve for x as follows:
h(x) = 3x - 19
71 = 3x - 19
3x = 71+19
3x = 90
x = 90/3 = 30
