Ok hi so I’m going to help you solve on this equation, if I solved this correctly can you please mark me as brainiest? I’d really appreciate it. Anyway let’s get started!

What we need to do is cancel both like terms on both sides of this equation which is
8=8 and you remove them.

Then you are left with -2y-3y=-5y-12

What you need to do is add -2y-3y because they are like terms

Now you have -5y

Then you put -5y=-5y-12

So you have to now cancel equal terms on both sides of this equation which were “-5y=-5y”, then you turn them into a 0

Now you are left with 0=-12

Therefore the statement is false for any value of y.

Jared uses 24 tiles to cover the top of his desk.of the 24 tiles,3/4 are blue. How many of the tiles are blue
rewona [7]
We multiply the fraction of 3/4 to the whole number 24 to get the equivalent number of the fraction.

24 * 3/4 = (24 * 3)/4 = 72/4 = 18

3/4 of 24 is 18.

There are 18 blue tiles out of the 24 tiles used.

Evaluate fog and gof if f(x)=5x-8 and g(x)= x^3
DerKrebs [107]

Answer:

see explanation

Step-by-step explanation:

note that f ○ g = f(g(x))

To evaluate substitute x = x³ into f(x)

f(g(x)) = f(x³) = 5x³ - 8

In the same way

g ○ f = g(f(x))

To evaluate substitute x = 5x - 8 into g(x)

g(f(x)) = g(5x - 8) = (5x - 8)³
