Answer:
f = -5, s = -6
Step-by-step explanation:
F= first number
S= second number
4f - s = -14
f + 3s = -23
3(4f - s = -14)
12f - 3s = -42
+ f + 3s = -23
13f = -65

13
f = -5
4f - s = -14
4(-5) - s = -14
-20 - s = -14
+20 +20
-s = 6

-1
s = -6
Answer:
Step-by-step explanation:
Order is impotant since you could easily make a positve number negative and vice versa. You switch the order of 5 subtracted by y to y-5.
It would be 4. in the equation y=mx+b, b is the y-intercept.
20
Formula for perimeter: length x 2 + width x 2
70x2 is 140 then subtract it from 180 and you’ll get 40, then you half it and get 20
