Answer:

C. x > -1

Step-by-step explanation:

The line intersects on the x-axis at -1 and is shaded towards the right, which are all numbers greater than -1. The inequality that matches this is x > -1.

If the variable was y, then the line would be horizontal on the y-axis. If the inequality was x > 1, then the line would intersect on the x-axis on positive 1. This is why the other options are incorrect.

hope this helps!

Answer: x>-1

Step-by-step explanation:

Dotted line on the axis is covering y infinitely, so theres an inequality on x, and the line is at -1, so x should be > - 1

For ABC:

The interior angle of C is 180 - 142 = 38
The three interior angles add up to 180°
(2x - 15) + (x - 5) + 38 = 180
3x - 20 + 38 = 180
3x + 18 = 180
3x = 162
x = 54

The measure of angle ABC = x - 5 = 54 - 5 = 49

For JKL:
The interior angle of L is 180 - 100 = 80°
The 3 interior angles add up to 180°
(2x + 27) + (2x - 11) + 80 = 180
4x + 16 + 80 = 180
4x + 96 = 180
4x = 84
x = 21

The measure of angle JKL is 2x - 11 = 2(21) - 11 = 42 - 11 = 31°

25 — 3x = 40<br> x =<br><br> Please answer quick thanks

Answer:

x=-5

Step-by-step explanation:

-3x+25=40. You want to isolate x so you have to subtract 25 from both sides. -3x=15. We then want x to be isolated so we have to divide both sides by -3 to make x by itself. x=-5. Therefore, x=-5.
