Y = mx + b
m is the slope, therefore the slope of y=-3x+2 would be -3
Hope this helps you, and good luck on the rest of the problems!
Answer:
Step-by-step explanation:
Left hand side is a positive number. Right hand side is positive. The equation should have real roots. (worst case, the root would be complex, but let's not open that can of worm)
Let's start noticing that and then take the square root of both sides, remembering that we need to take a plus or minus sign ( both a and -a squared give the same result!)
Step-by-step explanation:
1) -5x<35
we divide both sides by 5
-5x/5<35/5
-x<7
we divide both sides by-1 to remove the negative sign
-x/-1<7/-1
x<7/-1
2) 2x>-42
we divide both sides by 2
2x/2>-42/2
x>-21
3) x/3≤-7
we multiply by 3 and we cancel 3
3(x/3)≤3(-7) we cancel the 3
x≤-21
4) x/-4≥-4
we do the same thing
x≥1
1044 is divisible by 2, 3, 6, and 9. You're welcome. ;)
