A parallelogram should have 2 sets of parallel lines. Let's find the slope of line PQ and RS to test.

PQ:
(4-2)/(1-(-3))
2/4
1/2

RS:
(2-0)/(3-1)
2/2
1

Because 1 does not equal 1/2 (the slopes are different) the lines are not parallel. Thus, the figure is not a parallelogram.

How do I solve -2m=16m-9
Brums [2.3K]
-2m = 16m - 9

First, take '16m' from both sides.
-2m - 16m = -9
Second, add '-2m - 16m' to get '-18m'.
-18m = -9
Third, divide both sides by '-18'.
m =  \frac{-9}{-18}
Fourth, change the fraction into a negative.
m =  \frac{9}{18}
Fifth, find the GCF of 9 and 18.
The GCF is 9.
Sixth,  divide the numerator by the GCF.
9 ÷ 9 = 1
Seventh, divide the denominator by the GCF.
18 ÷ 9 = 2
Eighth, rewrite the fraction in simplest form.
m =  \frac{1}{2}

Answer as fraction: m =  \frac{1}{2}
Answer as decimal: m = 0.5

A angles of an equilateral triangle are congruent. If x represents the measure of the third angle of the triangle, what is x?
Tatiana [17]

Answer:

D

Step-by-step explanation:

Since x is the measure of the third angle and all 3 angles are congruent then

All 3 angles have a measure of x

The sum of the 3 angles in a triangle = 180°, this

x + x + x = 180 ← is the required equation

3x = 180 ( divide both sides by 3 )

x = 60

Jlenok [28]

Answer:

Do you mean to round the number 653,500,653,500,653,500? Or do you mean to round the number 653,500? If so, for 653,500, the digit in the thousand's place is 5, so it's already rounded to the nearest thousands place.
