Answer:
O No. She used the wrong slopes when graphing the equations.
Step-by-step explanation:
2(3x+4y) = 2(24)
6x+8y = 48
Add both the equations
6x + 8y = 48
+ x - 8y = -20
—————————
7x = 28
x = 28/7
x = 4
Plug in this value in the second equation
(4) - 8y = -20
-8y = -24
y = -24/-8
y = 3
Therefore:
x = 4
y = 3
Answer: C
Step-by-step explanation: im sorry if its wrong creati deleted all my points and im at -92 points
0.25 represents the slope of the line. For every 1 unit it goes up, it goes 4 to the right.
(8*5*4) + (4*4*4)
8*5*4 for the prism at bottom
4*4*4 for the cube on the top
