Help please! Figure JKLM is a parallelogram. The measures of line segments MT and TK are shown. What is the value of MT? A.) 7 B
Zinaida [17]

Hey there! :)

Answer:

C) 74 units.

Step-by-step explanation:

MT is congruent to KT because the diagonals of a quadrilateral bisect each other. Therefore:

8y + 18 = 12y - 10

Subtract 8y from both sides:

18 = 4y - 10

Add 10 to both sides:

28 = 4y

Divide both sides by 4:

28/4 = 4y/4

y = 7 units. Plug this into the equation for MT:

8(7) + 18 = 74 units.

ANSWER FAST PLSSSS!!
Art [367]

Rotating counterclockwise 270 degrees would make the original Y value the new X value and the original x value would become the new Y value with the opposite sign.

So the new location would be (-9, 8)

Plzzzzzzzzzzzzzzzzzz need help
vlada-n [284]

Answer: A

Step-by-step explanation:

4x+4y=20

We need to get this form: y=mx+b

we need to begin by isolating y on the left side. To do this, we must subtract 4x.

4y=20-4x

Rewrite it so that we get this form: y=mx+b

4y=-4x+20

Since y needs to be completely isolated, divide by 4.

y=-\frac{4x}{4} +\frac{20}{5}

Divide;

y=-x+5
