H(x) = 5.7 −19x

A.
-127.3
B.
-138.7
C.
0.67
D.
138.7

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!

19.

step-by-step explanation:

you add the 9 in the tens column since it is a single digit and 9 plus zero is 9 so it is 19
