Hi there!
We are basically asked to solve each equation for x. Here...
A. 
2 + x = 5
-2        -2
x = 3
B.
x + 1 = 4
x = 3
C.
9 + x = 6
x = -3
D.
x + (-4) = 7
x - 4 = 7
x = 11
E.

Answer:

C. -3/2

Step-by-step explanation:

Perpendicular lines have negative reciprocal slopes.

We know that line <em>m </em>is perpendicular to line <em>l. </em>

Line <em>l </em>has a slope of 2/3. To find the slope of line <em>m, </em>find the negative reciprocal of 2/3.

Negative: switch the sign

2/3 --> -2/3

Reciprocal: switch the numerator (top number) and denominator (bottom number)

-2/3 --> -3/2

Line <em>m</em> has a slope of -3/2 and C is correct.

Geometric proofs. I just don’t understand it and my teacher isn’t helping.
pshichka [43]
The midpoint of a line can be represented by the point that is in the very center of the line. A line segment such as AT also represents half of the line. The symbol of the tilde with the equal sign underneath represents congruence meaning the two segments are the same. Therefore each equation shows the same true statement in a different form
