Answer:
x = - 3/7
y = - 8/7
Step-by-step explanation:
(2x - 6y = 6)/2 =
x - 3y = 3
x = 3y + 3
Substitution:
6 (3y +3) - 4y = 2
18y + 18 - 4y = 2
14y = -18+2
y = -16/14
y = - 8/7
Substitution:
x = 3(-8/7)+3
x = -24/7 + 3
x = -3/7

Answer:
13/17
Step-by-step explanation:
Since we have 30 total students and 17 girls you would subtract 30-17 to get 13 and that would be boys, so the ration from boys to girls would be 13/17.
Answer:
g(x) = x^2 - 7
Step-by-step explanation:
gf(x) = x^2 + 6x + 2
Converting to vertex form:-
g(fx) = (x + 3)^2 - 9 + 2
= (x + 3)^2 - 7.
As you replace the x in g(x) with f(x) in order to get g(f(x) then,
since f(x) = (x + 3), g(x) is x^2 - 7 (answer)
