-30m^3-3 here is your answer

This is your answer. If you still need it:

3m/m-6 * 5m^3-30m^2/5m^2

First you need to put the numerators and the denominators together in the same "line" or "fraction if you would say.

(3m)(5m^3-30m^2)/(m-6)(5m^2)

Then you would use the distributive property and then multiply the expressions. No dividing yet.

15m^4-90m^3/5m^3-30m^2

Now you simplify with the power of exponents rule

15m-90m/5-30

Now you normally simplify by just subtracting

-75m/-25

Then simply simplify the constants

3m (The answer is 3m because -75/-25=3 positive whole numbers always stay on top [numerator], if it were negative and still on the denominator, using power of exponent rules, you would switch it up to the numerator, or "flipping" the constant or variable)

I'm stuck on this one:( help me please ​
ZanzabumX [31]

Answer:

Step-by-step explanation:

f-1(x) is the inverse of f(x)

to find the inverse let’s set the equation up like this

y = 4x -2

now we’ll switch x and y

x = 4y -2

and solve for y

x + 2 = 4y

x/4 + 2/4 = y

the inverse is

y = x/4 + 1/2

this equation is written in y = mx + b form

where b = y intercept

so the y intercept is 1/2
