Which linear equations does the graph show the solution to? Select all that apply. y = 2x + 13 y = –x – 2 y = 3x – 5 y = negativ
salantis [7]

Answer:

y = 2x + 13

y = –x – 2

Step-by-step explanation:

The options are:

y = 2x + 13

y = -x - 2

y = 3x - 5

y= -(1/2)x + 6

y = -2x - 2

The graph is shown in the figure attached. There, point (-5, 3) is shown. Replacing it into the equations we get:

y = 2(-5) + 13  = 3    (so, it is a solution)

y = -(-5) - 2 = 3     (so, it is a solution)

y = 3(-5) - 5  = -20 ≠ 3   (so, it isn't a solution)

y= -(1/2)(-5) + 6  = 8.5 ≠ 3     (so, it isn't a solution)

y = -2(-5) - 2 = 8 ≠ 3     (so, it isn't a solution)

pentagon [3]
I'm kinda guessing but I think it's 4.5 square feet because each triangle has 108 inches of area when you multiply by 6 you get 648 then from there you turn that into square feet

Given a = 4 and b = -2, evaluate -|b - a|. Please help!
Sergeeva-Olga [200]
The answer is:  - 6 .
_____________________________________________

Evaluate the value INSIDE the "bars". 
  b - a  =  -2  -  4  = -6 .  The absolute value of the value inside inside the bars is the "positive" number of that value.  The value is negative 6; so, the absolute value, or "magnitude", of "-6", is "6";  Then, then "-" (6) = -6.  So the answer is: -6 .
