Answer:
28 degrees
Step-by-step explanation:
A triangle is always equal to 180 degrees so add the degrees together
40+2x+3x=180
40+5x=180
5x/5=140/5
x=28
The answer is clearly b makes the most sense
X=2
its x=2 because you have to divide -20x by -40 so the two negatives cancel out each other and then you get 2.
Answer:
B.
Step-by-step explanation:
Domain is the x-coordinate and the range is the y-coordinate.
B. Domain: {7}
Range: {-4, -2, 1, 4, 6}
<span>Slope of JK=((-1)-2)/(4-(-3)=-3/7
Slope of KL=((-5)-(-1)/(2-4=2
Slope of LM=((-2)-(-5))/(-5-2)=-3/7
Slope of MJ=(2-(-2))/((-3)-(-5))= 2
JK is parallel to LM and KL is parallel to MJ. Therefore JKLM is a parallelogram.</span>
