Answer:

1 solution.

Step-by-step explanation:

1/2(x + 12) = 4x - 1

Expand the brackets.

1/2x + 6 = 4x - 1

Subtract 6 and 4x and both sides.

1/2x - 4x = -1 - 6

-7/2x = -7

Multiply -7/2 on both sides.

x = -7 × -2/7

x = 14/7

x = 2

What is the distance between the following points?

GaryK [48]

Point are

(2,-3)
(8,-9)

Using distance formula

$\\ \sf\longmapsto \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

$\\ \sf\longmapsto \sqrt{(8-2)^2+(-9+3)^2}$

$\\ \sf\longmapsto \sqrt{6^2+(-6)^2}$

$\\ \sf\longmapsto \sqrt{36+36}$

$\\ \sf\longmapsto \sqrt{72}$

$\\ \sf\longmapsto 8.2units$
