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.

step-by-step explanation:

vote !

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
