Hi Ella

|7x + 4| = 18
Solve absolute value
We know either 7x + 4 = 18 or 7x + 4 = -18
There are 2 possibilities but we gonna solve it one after another
Lets start with possibility 1
7x + 4 = 18
7x = 18 - 4
7x = 14
x= 14/7
x= 2
Now, lets solve for possibility 2
7x + 4 = -18
7x = -18 - 4
7x = -22
x= -22/7

Final answers : X = 2 or x = -22/7

I hope that's help !

Find the distance between (-7,-2) and (11,3)

jarptica [38.1K]

Answer:

The answer is

<h2> $\sqrt{349} \: \: units$ </h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

<h3> $d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\$ </h3>

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-7,-2) and (11,3)

The distance between the points is

<h3> $d = \sqrt{ ({ - 7 - 11})^{2} + ({ - 2 - 3})^{2} } \\ = \sqrt{ ({ - 18})^{2} + ({ - 5})^{2} } \\ = \sqrt{324 + 25} \\$ </h3>

We have the final answer as

<h3> $\sqrt{349} \: \: units$ </h3>

Hope this helps you
