Answer:
x = 7 is your answer.
Step-by-step explanation:
Here is what you do:
<em>x + 16 = 4x - 5</em>
<em>-3x + 16 = -5</em>
<em>-3x = -21</em>
x = 7 is your answer.

Answer:
Step-by-step explanation:
We can start by finding the third side of the triangle/the side of the square using the Pythagorean Theorem:
In this case the side length of the square would be represented by the variable "c" as it is the hypotenuse:
Since the area of a square is the side length square then...
The square root and the squared cancel out giving us...
3(18 - x/3 = -7)
54-x = -21
-x = -75
x = 75
Answer:
y = -1x -4
Step-by-step explanation:
The point slope equation is y - y1 = m(x -x1).
You will have to plug in the points (-3, -1) and (2, -6).
y - (-1) = m (x - (-3))
To find "m", find y over x.
m = (y2 - y1) / ( x2 - x1)
m = (-6 + 1)/(2 + 3)
m = -5/5
m = -1
Then plug in "m"
y + 1 = -1(x + 3)
then distribute the "m" into the parenthesis and isolate y or subtract 1 from both sides.
y + 1 = -1x - 3
y = -1x -4
