Answer:
1. Even - B
2. Even - B
3. Odd - A
Step-by-step explanation:
Example 1: 7+7 = 14
7 is odd, 14 is even.
Example 2: 4 + 4 = 8
4 is even, and 8 is even.
Example 3: 4 + 5 = 9
4 is even, 5 is odd, 9 is odd.

Answer:
x=−2 and y=−1
Step-by-step explanation:
<u>Problem:</u>
Solve y=x2;y=−x−3
<u>Steps:</u>
I will solve your system by substitution.
y=1/2x;y=−x−3
Step: Solve y= 1/2x for y:
Step: Substitute 1/2 x for y in y=−x−3:
y=−x−3
1/2x= =−x−3
1/2x+x=−x−3+x(Add x to both sides)
3/2x = -3
3/2x/3/2 = -3/3/2 (Divide both sides by 3/2)
x=−2
Step: Substitute −2 for x in y=1/2x:
y=1/2x
y=1/2(-2)
y=−1(Simplify both sides of the equation)
<u>Answer:</u>
x=−2 and y=−1
