Answer: 16875x³-13500x²+3600x-320

Step-by-step explanation:

[gοfοh](x) means g(f(h(x))). So you plug in h(x) into f(x) and that into g(x).

f(3x)=5(3x)-4=15x-4

g(f(3x))=5(15x-4)³

g(f(3x))=5(3375x³-2700x²+720x-64)

g(f(3x))=16875x³-13500x²+3600x-320

A Christmas jar contains 550 m&ms. Of all the m&ms, 2/5 are green and the rest are red. What is the ratio of green to re
vazorg [7]

Answer:

2:3 unless it wants it in total, then 220:330

Step-by-step explanation:

it gives you the answer with the fraction.  A ratio is basically saying with x:y for every x number of one thing there are y number of another.  In this case we know 2/5 will be green, so how many will be red?  3/5.  So for every 2 greens there are 3 reds.

Another way of looking at it is for the totals.  there are 550 total, so 2/5 of that is green.  2/5 of 550 is 220, while 3/5 is 330  so that means of the 550, the ratio is 220:330.  Kinda like simplifying fractions where 220/550 is the same thing as 2/5

3(2c-8) - 10c > 0 can some one explain how to solve this ?​
Jet001 [13]

Answer:

c < - 6

Step-by-step explanation:

Given

3(2c - 8) - 10c > 0 ← distribute and simplify left side

6c - 24 - 10c > 0

- 4c - 24 > 0 ( add 24 to both sides )

- 4c > 24

Divide both sides by - 4, reversing the inequality symbol as a consequence of dividing by a negative quantity.

c < - 6
