Take 2 points :-
if x = 0 y = -0-21 = -21 , point A = (0,-21)

if y = 0 0 = -x - 21 so x = -21, point B = (-21,0)

Plot points A and B and draw a line through these 2 points.

You would put -21 on bottom right on the x axis and -x on the top left on the y axis

-x - 9 $\geq 5$

You want to get x by itself.

First subtract 9 from both sides of the equation.

-x - 9 $\geq 5$
+9 +9

-x $\geq 14$

Then divide -1 on both sides.

-x/-1 $\geq 14/-1$

I'm pretty sure when you divide a negative number when solving inequalities, you switch the sign.

x $\leq 5$

8 ft 6 inches is greater or less than 100 inches?

Romashka [77]

It would be greater, because 1 foot is equal to 12 inches. 8 times 12 is 96. Then 96 plus 6 inches in 102. So it would be greater.

What is -6 multiplied by 1/2

kirill115 [55]

Turn the fraction into a decimal,so 1/2 would be .5 and then multiply that into -6 which would be -3
