Answer:
B) −2
Explanation:
When x is positive then y is positive integer.
When x is negative then y is negative integer.
<u>For Option A</u>
- y = -1 [x is negative so is y]
<u>For Option B</u>
- y = 1 [<u>x is negative</u> but <u>y is positive</u>]
<u>For Option C</u>
- y = 7 [x is positive so is y]
<u>For Option D</u>
- y = 9 [x is positive so is y]
So k in the first problem would =1/2
and i guess in the second problem just put k in place of the first space and in the second space put 8 for x. y would then =4. Idk if I did this right, though, I'm honestly a little confused too.
Answer:
Add 10 to three times the value of x minus 7.
