First take x + 2y = 6 and isolate x:
x = 6 - 2y
Then substitute that for x in 2x + 3y = 4:
2(6 - 2y) + 3y = 4
12 - 4y + 3y = 4
12 - y = 4
-y = -8
y = 8
Substitute y = 8 into x + 2y = 6 and 2x + 3y = 4:
x + 2(8) = 6 --> x + 16 = 6 --> x = -10
2x + 3(8) = 4 --> 2x + 24 = 4 --> 2x = -20 --> x = -10
y = 8 and x = -10
Answer:
x would equal 3
Step-by-step explanation:
trust me it's right I'm just bad at using that
Answer:
y=3x-9
Step-by-step explanation:
put into slope formula y2-y1/x2-x1 and then after finding the slope you put on the points into the equation y=3x+b and you find the b giving you the equation
Answer: 
Step-by-step explanation:
I could show you how to solve it but it's a long process... basically calculate the area of the pyramid and the area of the rectangular prism individually and add them.
