Answer:
x= 0 , y= -8
Step-by-step explanation:
Add the 2 equations together, you would get:
9x = 0
Divide both sides by 9:
x = 0/9
x=0
Substitute the value of x in one of the equations to get the value of y, I picked the first one (5x+2y = -16)
5(0) +2y = -16
0+2y = -16
2y = -16
Divide both sides by 2:
y = -8
To answer this question we need to add 39.95+1.95=41.9
Then just subtract: 90.75-41.9=48.85
The answer is 48.85.

2*9 = 19
18*3 = 54
54*45 = 2430

</span>a^2<span> – b^</span>2<span> = (a + b)(a – b)
</span>in this case
<span>(–7x + 4)(–7x – 4)
answer
</span><span>(–7x + 4)(–7x – 4)</span>
-6x + y= -7
Add 6x on both sides to isolate y
Y= 6x-7
The slope is 6 and the y-intercept is -7
Hope this helps!
Please mark me as brainliest if you can, I really appreciate it!
