Question

Consider f(x) = 1.8x – 10 and g(x) = −4. Select the equation that can be used to find the input value at which f (x ) = g (x ), and then use that equation to find the input, or x -value. 1.8x – 10 = –4; x = 1.8x = –4; x = 1.8x – 10 = –4; x = –4 = x

Answer 1

Answer:

Option A- 1.8x – 10 = –4; x = 1.8 x minus 10 equals negative 4; x equals StartFraction 10 Over 2 EndFraction.

Answer 2

F(x) = g(x)

1.8x - 10 = -4      collect like terms

1.8x = 6              divide both sides by 1.8

x= 3.33
