Need answers and work shown anyone know how to do this

1) C. Because it says the number of years SINCE 2000.

2) The negative integers are -4, -3, -2, -1 because these are the only negative numbers between -5 and 5.

3) Put the point, which should be shaded in on -6 and color the rest of the line to the left because it claims that -6 is LESS THAN or equal to x. Tip: If you have a variable alone on the left side EX: x<5, then you have to shade the way the arrow, or sign is pointing. Remember, this does not include variables with numbers in from of them EX: 3x>8. In this situation, you would have to divide 8 by 3 and then you can work with it.

the f

last graph i believe

step-by-step explanation:

worked it out i believe

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130
