Answer 2

thanks

Answer 3

wats 5>9+r and how would it look on a number line

Answer 4

The answer is y=18.

y=(-7)(-2)+4
y=14+4
y=18

Answer 5

is that the answer to the first or second question

Answer 6

y=18 is the correct answer, not y=10. when you multiply 2 negatives, it will become a positive, making it +14+4=18. For your second question, 5>9+r. Simply subtract 9 from both sides making it -4>r. Then to put it on a number line, just put an open circle on x=-4 and indicate that r is everything that is smaller than than -4, so shade the number line to the left for all negative numbers less than -4.
