I need to solve for x and I’m confused it’s about angels please help me

likoan [24]

Both 52 and 5x-8 are equal to each other due to being parral.
SO 5x-8=52

Add both sides.
8+8 52+8= 60

5x 60
Now divide both sides by 5 and you get 12=x Hope this helps!

Write an inequality to represent the graph.

Goshia [24]

Answer:

$y \leq -\frac{3}{4}x+2$

y is less than or equal to negative three fourths times x plus 2

Step-by-step explanation:

step 1

Find the equation of the solid line

we have the coordinates (0,2) and (4,-1)

Find the slope m

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute

$m=\frac{-1-2}{4-0}$

$m=\frac{-3}{4}$

$m=-\frac{3}{4}$

Find the equation of the line in slope intercept form

$y=mx=b$

where

m is the slope

b is the y-intercept (value of y when the value of x is equal to zero)

we have

$m=-\frac{3}{4}$

$b=2$ ---> is given

substitute

$y=-\frac{3}{4}x+2$

Remember that

The shading area is below the line

therefore

The inequality is

$y \leq -\frac{3}{4}x+2$

y is less than or equal to negative three fourths times x plus 2

What is the step by step process of this problem? 6+2[-8-3(2x+4)]+10x

Romashka [77]

So with more than one pair of parentheses, you must start from the inside and make your way outside.

So firstly, distribute -3 to (2x + 4):

$6+2[-8-6x-12]+10x$

Next, combine like terms:

$6+2[-6x-20]+10x$

Next, distribute 2 to [-6x - 20]:

$6-12x-40+10x$

Lastly, combine like terms and your final answer will be $-2x-34$
