Answer:

x = – 2 —> y = 4.5

x = -1 —> y = 4

x= 0 —> y = 3.5

x =1—> y = 3

x=2 —> y=2.5

x=3 —> y= 2

Step-by-step explanation:

x = -2 —> x + 2y = 7 —> -2 + 2y = 7 —> 2y=7+2—> 2y = 9

y= 9/ 2 —> y = 4.5

x = -1 —> -1+2y =7 —> 2y =7+1 —> 2y=8 —> y=8/2 —> y= 4

x= 0 —> 0+2y=7 —> 2y=7 —> y =7/2 = 3.5

x= 1—> 1+2y=7—>2y =7-1—> 2y=6 —> y = 3

x =2—> 2+2y=7 —> 2y= 7-2—> 2y = 5 —> y=5/2=2.5

x=3—> 3+2y=7 —> 2y=7-3—> 2y=4 —> y=2

I need help ASAP , so what’s the answer
aivan3 [116]

The answer would be A.) 1

To find this answer you solve for x. Subtract 3/2 from both sides. This will give you 1/2x = 1/2^x. Then, divide by 1/2 on both sides to get x = 1.

To check this fill in x with 1. Then solve.

  • 1/2 * 1/1 + 3/2 = 2^1
  • 1/2 + 3/2 = 2
  • 4/2 = 2
  • 2 = 2

Thus making 1 the answer. Here's an image to show how I got this. I hope this helps!
