So when you are trying to find the solution to the system of equations make sure that you have it where y= -4/5x-6 and y= -30 are written like this:
-30=-4/5x-6
And then solve for x:
Add 6 on both sides.
-24=-4/5x
Then multiply by the reciprocal of -4/5.
-5/4*-24=-5/4*-4/5x
x=30
But then you are gonna want to plug 30 in for x in y=-4/5x-6 to make sure that it is the same as y=-30.
Try A:
6^(2*1.87) = 813.365
Try B:
6^(2*1.61) = 320.366
Try C:
6^(2*3.73) = 638275.725
Try D:
6^(2*1.13) = 57.362
Which one seems like the best answer?
