Answer:
your answer is 15.6
Step-by-step explanation:
5x divided by 3= 26
multiply 3 by each side
5x = 78
divide 5 by each side to get x by itself
x= 15.6
The only answers you can really use is the first and fifth ones.
The second one is not true because the point do not look random. they look like they might be a parabola
The third one is not a choice because plot does not have a linear (straight line) pattern. Linear means straight line.
The fourth one is not true. There is only 1 point below the x axis. The rest are above the x axis.
The 5th one is true.
The 6th one is not true. Those points do not have a straight line pattern.
Notice that both equations contain + 2y so if we subtract the first equation form the second we get:-
8x - 7x + 2y - 2y = 30 - 24
x = 6
Now to find the value of y we substitute for x in the first equation.
7(6) + 2y = 24
2y = 24 - 42
2y = -18
y = -9
So the solution to the system of equations is x = 6 , y = -9 (answer)
I found the answer to the same question you have.
