Variable squared minus negative 2
<u>Answer</u>:
Jared is right.
<u>Explanation</u>:
proof 1:
10 - 4 = 6
6 = 6
second proof:
10-3 - 4 = 6 - 3
10 - 7 = 3
3 = 3
third proof:
10 - 4 - 3 = 6 - 3
10 - 7 = 3
3 = 3
Hence for all LHS = RHS proved and Jared is correct.
Answer:
y=1, x=2
Step-by-step explanation:
x+y=3
x-y=1
Using elimination method
x-x+y--y=3-1
2y= 2
y=1
Substitute y=1 into equation 2
x-1=1
x=1+1
x=2
Answer:
there is no gragh
Step-by-step explanation:
Answer:
y = -16.9
Step-by-step explanation:
<u>→Add 0.8y to both sides:</u>
-0.8y + 5.49 = -19.86 - 2.3y
5.49 = -19.86 - 1.5y
<u>→Add 19.86 to both sides:</u>
25.35 = -1.5y
<u>→Divide both sides by -1.5:</u>
-16.9 = y
