Answer:

EF = 10

Step-by-step explanation:

DE + EF = DF

5x + x + 8 = 20

6x = 20 - 8

6x = 12

x = 12/6

x = 2

EF = x + 8 = 2 + 8 = 10

Fone the slope of a line that is perpendicular x = -12
Vinvika [58]

Answer:

m [slope] = 1/12

Step-by-step explanation:

If a line is perpendicular (90 degrees, forms a right angle) to another, the slope of the line must be an opposite reciprocal of the other. The opposite reciprocal of m is -1/m.

An opposite reciprocal is created by flipping the numerator and denominator, and making it negative.

Therefore, if m is -12 it's opposite reciprocal is -1/-12 = <u>1/12</u>.

Write and solve an equation based off the verbal phrase: 6 more than x is equal to 33
kenny6666 [7]

Answer:

x + 6 = 33

Step-by-step explanation:

6 more than x means there's an increment in the value of x by addition of 6

x + 6 = 33

This leads to an algebraic linear equation. x is an unknown variable and can be solved for

we subtract 6 from both sides of the equation

x + 6 - 6 = 33 - 6

x = 27

Therefore, we can say 6 more than 27 is 33
