Answer:
(7,2)
Step-by-step explanation:
5x + 3y = 41
3x - 6y = 9
Multiply the first equation by 2
2(5x + 3y) = 41 *2
10x +6y = 82
Add this to the second equation
10x +6y = 82
3x - 6y = 9
----------------------
13x = 91
Divide by 13
13x/13 = 91/13
x=7
Now we can find y
5x+3y = 41
5(7) +3y =51
35+3y=41
Subtract 35 from each side
35-35+3y=41-35
3y = 6
Divide by 3
3y/3 = 6/3
y=2
Answer:
9: 14
Step-by-step explanation:
Both terms are divisible by 4.
Answer:
20.
Step-by-step explanation:
When x = 2
f(x= 3(2)^3 + 2^2 - 8
= 24 + 4 - 8
= 20.
It’s C. I have to put more letters just ignore this
