Question

H(x) = 5.7 −19x A. -127.3 B. -138.7 C. 0.67 D. 138.7

Answer 1

Answer:

x = 0.3 (see below)

Find the x intercept/zero.

To find x intercept/zero, subsitute H (x) = 0.

0 = 5.7 - 19x

Move the variable to the left hand side and change the symbol.

19x = 5.7

Now, divide both sides.

x = 0.3

Solution is 0.3

Alternate solution is x = 3/10.

Hope it helps!
