Answer:
x = 2.6, y = 2.2
Step-by-step explanation:
if 4y = 2 + 3x - 1 and
y = 2x - 3,
4y = 2 + 3x -1 and 4y = 8x - 12 so
8x - 12 = 2 + 3x - 1
so 5x - 12 = 1,
5x = 13,
x = 2.6
If x = 2.6,
y = 5.6 - 3
so y = 2.2

Answer:
100.5cm2
Step-by-step explanation:
v=pi(r)2(h)
v=3.14(2)2(8)
v=3.14(4)(8)
v=100.48
v=100.5cm2
Answer:
Hello There. ☆~\---___`:•€`___---/~☆ The correct answer is C. Both (1,3) and (-2,-4).
To check whether (-2,-4) is a solution of the equation let's substitute x= -2 and y= -4 into the equation:
-7x+3y=2
-7*(-2)+3*(-4)=2
14-12=2
2=2
Do the same thing with (1,3)
-7x + 3y = 2
-7 * 1 + 3 * 3 = 2
-7 + 9 = 2
2 = 2.
