5/2= x/(1/7)

cross multiply left numerator by right denominator and right numerator by left denominator

(5)(1/7)= (2)(x)
multiply 5 by fraction's numerator

(5*1)/7= 2x
5/7= 2x

divide both sides by 2
5/7 ÷ 2=

to divide fractions, multiply by the reciprocal/inverse

5/7 * 1/2= x
(5*1)/(7*2)= x

multiply numerators; multiply denominators
5/14= x

ANSWER: x= 5/14

Hope this helps! :)

If f(x) = 5x-3, which expression represents its inverse function?
valentinak56 [21]

Answer:

Pretty sure it's C

Step-by-step explanation:

For inverse functions, I do the opposite operation

the only logical inverse function I see working in this expression would be C

divide the 5 from 5x and add the 3

Also, subtract the f(x) on both sides to get the "- y"

so, you get : 5/x + 3 = - y (f(x) is just "y")

Answer : y = -3/4x + 1

To find an equation that goes through the two points provided, you have to find the slope using those same two points.
The equation for slope is (y2-y1)-(x2-x1).

The slope is -3/4.

The y-intercept is already given to you in the point (0,1).

Just plug everything into an equation and you get y = -3/4x + 1.
