Absolute Value Equation | -4 + 5x |= 16 Please show how to do the problem.

1 answer:

4 0

If you have |a|=b, solve a=b and a=-b

so
|-4+5x|=16
so solve
-4+5x=16 and -4+5x=-16
add 4 to both sides
5x=20 and 5x=-12
divide both sides by 5
x=4 and x=-12/5

the 2 solutions are x=-12/5 and x=4

If < A and < B form a linear pair, and < A = x - 13 degrees, and < B = x + 7 degrees, then find x. Select one: a. 12

Andreas93 [3]

The correct value of "x" will be "93".

According to the question,

A linear pair of sum to 180°,

then

→ $x-13+x+7=180$

→ $2x -6=180$

By adding "6" both sides of the equation, we get

→ $2x-6+6=180-6$

→ $2x=186$

→ $x = \frac{186}{2}$

→ $x = 93$

Thus "option d" is the right answer.

$m= \frac{y_1-y_2}{x_1-x_2} \\ m= \frac{2-(-2)}{-4-(-1) } \\ m= \frac{4}{-3} \\ m=- \frac{4}{3}$
