Answer: 80% or 4/5

Step-by-step explanation:

so I don’t know how many numbers there are on this cube (a standard number cube has #1-6) but I’m going to go with 10 numbers (don’t know how this is possible but anyway-). I’ll edit my answer if needed.

10 numbers

10 (numbers) - 2 (#8 and #10) = 8 (possible numbers)

so 8/10 or 80%

reduced fraction: 4/5

percentage: 80%

fraction: 8/10

*will edit if needed

If f(x) = 7x+6 and g(x)=8x-4 find f(g(-2))
sp2606 [1]

Answer:

f(g(-2))=-134

Step-by-step explanation:

So we have the two functions:

f(x)=7x+6\text{ and } g(x)=8x-4

And we want to find f(g(-2)).

First, let's find g(-2):

g(-2)=8(-2)-4

Multiply:

g(-2)=-16-4

Subtract:

g(-2)=-20

Now, substitute:

f(g(-2))=f(-20)

Now, find the value of f(-20):

f(-20)=7(-20)+6

Multiply:

f(-20)=-140+6

Add:

f(-20)=-134

So:

f(g(-2))=-134

And we're done!
