HELP How does the subtraction<br> part of the expression change when a(b - c)<br> is expanded?
drek231 [11]

Answer:

The variables change

Step-by-step explanation:

Since we can't subtract c from -b we multiply both variables by  a because the question is telling us to subtract b and c then multiply the awnser by a, but we don't know what b and c is so we just multiply b and c by a. In the end we get ab-ac

If f(x) and its inverse function, f Superscript negative 1 Baseline (x), are both plotted on the same coordinate plane, where is
bearhunter [10]

Answer:

(2,2)

Step-by-step explanation:

step 1

Find the equation of f(x)

is a line that passes through the points (0,6) and (3,0)

Find the slope

m=(0-6)/(3-0)=-2

The function f(x) in slope intercept form is equal to

f(x)=-2x+6

step 2

Find the inverse

Let y=f(x)

y=-2x+6

Exchange the variables x for y and y for x

x=-2y+6

Isolate the variable y

2y=-x+6

y=-0.5x+3

Let

f^{-1}(x)=y

f^{-1}(x)=-0.5x+3

step 3

Solve the system of equations

f(x)=-2x+6

f^{-1}(x)=-0.5x+3

equate both functions

-0.5x+3=-2x+6

solve for x

2x-0.5x=6-3

1.5x=3

x=2

substitute the value of x in any of the functions

f(x)=-2(2)+6=2

The solution is the point (2,2)

therefore

Their point of intersection is (2,2)
