Answer:

B. f(x) = 5(x/4) - 3 and g(x) = [4(x + 3)]/5

Step-by-step explanation:

In the figure attached, the question is shown (the order of the options are different).

To find the inverse of a function, first, replace x with g(x) and f(x) with x, as follows:

f(x) = 5(x/4) - 3

x = 5(g(x)/4) - 3

Next, isolate g(x), as follows:

x + 3 = 5(g(x)/4)

4(x + 3) = 5g(x)

[4(x + 3)]/5 = g(x)

Sonja [21]

Answer:

On a coordinate plane, a curved line crosses the x-axis at (negative 1, 0), and crosses the y-axis at (0, negative 3). What are the intercepts of the graphed function? x-intercept = (–1, 0) a y-intercept = (–3, 0) b x-intercept = (0, –1) c y-intercept = (0, –3) d x-intercept = (0, –1) e y-intercept = (–3, 0) f x-intercept = (–1, 0) g y-intercept = (0, –3)

A scale model of an airplane has a length of 19 centimeters and a wingspan of 18 centimeters. The length of the real airplane is
deff fn [24]
The wingspan is 36 m.

Using a proportion to solve this, we write the scale factor as a ratio first:  19/38, since 19 is the size of the model's length and 38 is the real length.  For the second ratio, we have 18 for the size of the model wingspan and x for the real wingspan:

19/38 = 18/x

Cross multiply:
19*x = 38*18
19x = 684

Divide both sides by 19:
19x/19 = 684/19
x = 36 m

Steve has two pieces of PVC pipe of length 4 ft and 7 ft. Which of the following lengths of PVC pipe could be used as the third
Ratling [72]

Answer:

<em>10 feet</em>

Step-by-step explanation:

here's the reason ; -

let's take the missing side be x

we know, the one side of a triangle should always be greater than the difference between the other two sides, so ,

=》x > 7-4

=》x > 3

and the measure of a side should always be less than the some of the other two sides, hence

=》7 + 4 > x

=》11 > x

now, we have : -

11 > x > 3

value of x should be more than 3 and less than 11 , hence 2 ft , 3 ft and 12 ft can't be the measure of third side,

so, we got our third side as 10 ft
