Answer:

-88x + 10y

Step-by-step explanation:

-5x+3y= -93x+7y=23

we cannot do anything to numbers with unlike signs so we will do this

23=-5x+3y=-93x+7y

now we will take the numbers with like signs to one place like this

23=-5x+93x+3y+7y

now we can solve this

- x + = -

+ x+=+

-x-=-

23= 88x+10y ANSWER

Good morning

Answer:

B: (1, 5)

Step-by-step explanation:

This graph shows the solutions to the inequality: y > (1/3)x - 2

Since, 5 > (1/3)×1 - 2 then the point (1 ,5) is a solution to the inequality.

Help? I'm pretty confuse on both of these? Please explain?

MAVERICK [17]

35 is the first answer (BAE ~ DAC)
36. We must divide 20 by 2 to get 10 because all the other sides are 2x the size. 3x-5=10 (Add 5) 3x=15 (Divide by 3) x=5 so the last answer choice is correct.
