Answer:
x=2 y=8 ---> (2;8)
Step-by-step explanation:
2x+5y=44
6x-4=y
1.
2x+5(6x-4)=44
2x+30x-20=44
32x=64
x=2
2.
6x-4=y
6*2-4=y
12-4=y
y=8
11/12 for the first one and 1/3 on the second. I’m 100% sure but I’m sorry if it’s wrong. Have a great day!
The answer is D). 125 = 1.28f. This accounts for both sales tax and the cost of food.
Expand (x+2)^2: x^2 + 4x + 4 : remember that (a+b)^2 = a^2 + 2ab + b^2
So: x^2 + 4x + 4 - x^2 = 60
