Answer is b. ( -1, -5)
Answer is b. (-1, -5)
Step by step
Substitute the x and y values into both equations to find equality
Answer b. Makes both equations equal
2x + y = -7
2(-1) + (-5) = -7
-2 -5 = -7
-7 = -7
it equals now let’s do the 2nd one
x - y = 4
-1 -(-5) = 4
4 = 4
This one equals too. I did the math on the other three answers and they did not equal.

Answer: 24 cm^2
explanation: the area of the triangle would be 6 because (3*4)/2=6. the area of the larger rectangle would be 12 because 4*3=12. the missing side is found by subtracting 8 by 4. the smaller rectangle’s area would be 6 because 4*1.5=6. add 6, 12, and 6 together and you get 24. i hope this helps!!
