Answer:
65°
Step-by-step explanation:
All triangles equal 180 degrees. So just subtract the other values.
Not sure what alive by graphing means, but these are the equations on a graph. Red is y=4x+7 and blue is y=-3x.

Answer:
x ≥ 1 (how to graph is listed below)
Step-by-step explanation:
To find where we need to plot the line, we first need to solve the inequality for x:
-2x - 3 ≤ -5
(Add three to both sides)
-2x ≤ -2
(Divide both sides by -2, but we can't forget that whenever we multiple or divide by a negative number, the sign flips!)
x ≥ 1
To graph this on the number line, you would put a dot on the 1 and fill it in completely (you fill in the dot for a "___ and equal to" sign. ex. ≥, ≤)
Then you would make an arrow from the dot to the right on the number line (this is because x must be greater than or equal to 1, so it must be facing in that direction)
Step-by-step explanation:
here is the answer for your question
AB=6 but DE=2(AB) so DE=2(6)=12
I’m guessing
