The line passes by the points (2,-3) , (-2,5)
so the equation of a line passes by 2 points is (y-y1)/(x-x1) = slope
slope = (y2-y1)/ (x2-x1)
= (5-(-3)) / ( -2-2)
= 8/-4
= -2
then subs. in the 1st equation of the line
(y-(-3)) / ( x-2) =-2
so,, (y+3) = -2(x -2)
so the answer is the 1st one
to make sure ur equation is right subs in the equation by the point (0,1)
if R.H.S = L.H.S
then ur equation is right

-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 $\leq 5$

Evaluate.

aleksandrvk [35]

Answer: -2 4/15

Step-by-step explanation: To properly subtract, we need to find a common denominator. We can list the multiples of 3 and 5 to find the common denominator:

3: 3, 6, 9, 12, 15

5: 5, 10, 15

The first common multiple we see is 15.

Calculation:

3 · 3 = 9

9 + 1 = 10

3 1/3 = 10/3

5 x 5 = 25

25 + 3 = 28

-5 3/5 = -28/5

Now to convert into fifteen as the denominator:

-28/5 = -28 x 3/5 x 3 = -84/15

10/3 = 10 x 5/3 x 5 = 50/15

Now to subtract accordingly:

50/15 - 84/15 = -34/15

Final answer: -34/15 (can be reduced to -2 4/15).
