Answer:

False!

Step-by-step explanation:

As C is not equal to -13 (number line)

So, your answer would be false.

hope it helps!

We can write an equation for the number line. The open circle means < or >. Since the open circle is at 0, that means c is going to be less than 0. The equation will look like this:

c < 0

The lines goes to left and since their is an arrow at the end of it, it never ends. This means that all negative numbers are solutions to the inequality. This means that -13 will be a solution to the inequality. It also satisfies the inequality we wrote above:

-13 < 0 (-13 is less than 0)

Therefore, the answer is [ True ]

Best of Luck!

Three vertices of parallelogram ABCD are A(2,-6),B(-1,2),C(5,3).find the coordinates of vertex D

Check the first picture below.

for a parallelogram, it has to have two pairs of parallel sides, so BC || AD and AB || CD.

if two lines are parallel, they have the same slope, namely the <u>same rise and run</u>.

notice, the line BC has a run of 6 and a rise of 1, <u>arrows in red</u>, therefore, AD must also have a run of 6 and a rise of 1, so if we move from A 6 units over and 1 up, we'd end up at point D.

now, for part atop

Check the 2nd picture, in a parallelogram, opposite sides are parallel and opposite angles are equal, so if WLP is 144°, then PNW is also 144°.

in a parallelogram, diagonals bisect each other, so each cut the other in halves, so if PM is 9 then MW is also 9 and thus PW is just 9+9=18.

now, about QRST.

notice what we said about a parallelogram above, thus

$\bf 8x+13=11x-23\implies 8x+36=11x\implies 36=3x \\\\\\ \cfrac{36}{3}=x\implies \boxed{12=x} \\\\[-0.35em] ~\dotfill\\\\ 2y+12=4y-4\implies 2y+16=4y\implies 16=2y \\\\\\ \cfrac{16}{2}=y\implies \boxed{8=y}$
