30-60-90 triangle rule
x=16
Step-by-step explanation:
8 = given
8
= y
8*2= 16 = x
(2x)
Answer:
x=-7
Step-by-step explanation:
Simplifying
3(x + -2) = 5x + 8
Reorder the terms:
3(-2 + x) = 5x + 8
(-2 * 3 + x * 3) = 5x + 8
(-6 + 3x) = 5x + 8
Reorder the terms:
-6 + 3x = 8 + 5x
Solving
-6 + 3x = 8 + 5x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-5x' to each side of the equation.
-6 + 3x + -5x = 8 + 5x + -5x
Combine like terms: 3x + -5x = -2x
-6 + -2x = 8 + 5x + -5x
Combine like terms: 5x + -5x = 0
-6 + -2x = 8 + 0
-6 + -2x = 8
Add '6' to each side of the equation.
-6 + 6 + -2x = 8 + 6
Combine like terms: -6 + 6 = 0
0 + -2x = 8 + 6
-2x = 8 + 6
Combine like terms: 8 + 6 = 14
-2x = 14
Divide each side by '-2'.
x = -7
Simplifying
x = -7
Hey!
-------------------------------------------------
Point Slope Form: y - 7 = -5/2(x + 4)
Slope-intercept Form: y = mx + b
m = slope
b = y-intercept
We can automatically eliminate Option A and B because they are both written in point slope form when the questions asks for slope-intercept form.
We can also eliminate option C because the slope in the equation doesn't match the slope in the equation above.

Answer:
y = -5/2x - 3

Hope This Helped! Good Luck!
Let's set up this problem.
k+7=34
Subtract k from both sides.
k=27
