Answer:
Step-by-step explanation:
4/50 = 0.08
0.08(100) = 8%
if
for all x, then e is the Multiplicative Identity.
is this enough for you to get the answer?
First question: y = -2x - 1.
Second Question: y = -4x + 3
Third Question: y = -3x - 5
The work for the first problem is shown in the attachment. The 2nd and 3rd problems use different numbers.
3y = -1/2x + 2 . . . . . . . . (1)
y = -x + 9 . . . . . . . . (2)
substituting (2) into (1), we have
3(-x + 9) = -1/2x + 2
-3x + 27 = -1/2x + 2
-1/2x + 3x = 27 - 2
5/2x = 25
x = (2 x 25)/5
x = 10
From (2)
y = -10 + 9
y = -1
solution (10, -1)
2m - 6 = 8m
2m - 6 - 2m = 8m - 2m
2m - 2m - 6 = 8m - 2m
-6 = 6m
-6/6 = 6m/6
-1 = m
-1(3) = m(3)
-3 = 3m
3m = -3
