Answer:
(4, 0), (-4, 0), (0, -2), (0, 8)
Step-by-step explanation:
Alison can make 4. Because 1/2 of 8/1 = 4 if you cross out 2 and 8 so it would be 1/1 of 4/1
Answer:
J
Step-by-step explanation:
| -24x + 120| > 48
-24x + 120 > 48
-24x > 48 - 120
-24x > - 72
x < -72/-24
x < 3
-24x + 120 < -48
-24x < -48 - 120
-24x < - 168
x > -168/-24
x > 7
solution is : x < 3 or x > 7...answer B
Answer:
x = -2 and y = 0
Explanation:
You just put the value of one variable in terms of the other in one of the two equations. Then, solve it and BOOM you'll have your solution.
x + y = -2 ........... (a)
y = x + 2 ............ (b)
Put (b) in (a),
x + (x + 2) = -2
2x = -4 => x = -2
Put x = -2 in (b),
y = x + 2 = -2+2 = 0
Thus, x=-2 and y=0
