If f(x)=3x+2 and g(x)=x-1/3 what is the value of f{g(7)}

Mathematics

Answer:

f(g(7)) = 22

Step-by-step explanation:

First find the general form of the new equation, f(g(x)):

f(x)=3x + 2

g(x)=x - 1/3

f(g(x)) = 3(x - 1/3) + 2

You can simplify that, or alternatively just plug in 7 now and solve:

f(g(7)) = 3(7 - 1/3) + 2

f(g(7)) = 3(20/3) + 2

f(g(7)) = 20 + 2

f(g(7)) = 22

First figure out how many times 9 can go into 25 **do the highest amount of times it can go in-
<span><span>9x1=9 </span><span>9x2=18 </span><span>9x3=27 </span><span>9x4=<span>36
nine can go in 2 times because 3 times would be way to much
so you're mixed number would be 2
now to figure out you're numerator do 25-18=7
Now it would be 2 7/25
so you're mixed number,then the numerator,finally denomantor ALWAYS stays the same.

Answer:

<2 is 50º

Step-by-step explanation:

you first want to find what x is, so you would put the two equations in an (equation)=(equation) and get x and the number across from each other, that would be x=15º. you then plug in the 15 to the equation, and solve that, resulting in 130º. The angle is going to be 180 in total, so subtract the 130º from 180º and you would get 50º

Neko [114]
Jack must score 28 problems correct. To get a 92% he must answer 92% of the 30 questions right. which means 0.92*30=27.6, but it is not possible to score 0.6 of a problem right so you would round to 28, which guarantees Jack scores a 92 because if we round down, Jack would score less than a 92
