Answer:for the first one, you should probably do a table of values then answer the question, i usually find that helpful
Step-by-step explanation:
In order to arrive at the answer, take the total (251) and subract it by 148. J = 103
-x - y = -5
y = x + 1
-x -(x + 1) = -5
-x - x - 1 = -5
-2x = -5 + 1
-2x = -4
x = -4/-2
x = 2
y = x + 1
y = 2 + 1
y = 3
solution is : (2,3)
Answer:
n - (-4) ≥ 10
4(n+5) ≥ 48
Step-by-step explanation:
n - (-4) ≥ 10
n + 4 ≥ 10
n ≥ 6
4(n+5) ≥ 48
4n + 20 ≥ 48
4n ≥ 28
n ≥ 7
For this case we have the following expression:
Rewriting the expression we have:
We apply distributive property to the terms of parentheses:
