Answer:
x=8 ???
Step-by-step explanation:
??? not 100% sure but im pretty sure ;w;
the slope goes by several names
• average rate of change
• rate of change
• deltaY over deltaX
• Δy over Δx
• rise over run
• gradient
• constant of proportionality
however, is the same cat wearing different costumes.
and to get it, we simply need two points off of the straight line, hmm let's use the ones in the picture below.

Answer:
12
Step-by-step explanation:
the shapes are similar which means the sides are proportional, you can set up a ratio using the sides as 10/40 = 3/x
solving that gives you x =12

9e + -7 = 7e + -11
Reorder the terms:
-7 + 9e = 7e + -11
Reorder the terms:
-7 + 9e = -11 + 7e
Solving
-7 + 9e = -11 + 7e
Solving for variable 'e'.
Move all terms containing e to the left, all other terms to the right.
Add '-7e' to each side of the equation.
-7 + 9e + -7e = -11 + 7e + -7e
Combine like terms: 9e + -7e = 2e
-7 + 2e = -11 + 7e + -7e
Combine like terms: 7e + -7e = 0
-7 + 2e = -11 + 0
-7 + 2e = -11
Add '7' to each side of the equation.
</span><span>Combine like terms: -7 + 7 = 0
0 + 2e = -11 + 7
2e = -11 + 7
</span><span>Combine like terms: -11 + 7 = -4
2e = -4
Divide each side by '2'.
e = -2
Simplifying
e = -2</span>
