−4x+18>2x+12
−4x​+18−18>2x+12−18
−​4x−2x>2x−6−2x

−​6x>−6
Multiply both sides by −1 and reverse the inequality
(​−6x)(−1)<(−6)(−1)
6x<6
x<1
In interval notation (-∞, 1)

Why does.the equation y=3x+5 NOT represent a proportional relationship
sergiy2304 [10]

Answer:

The equation not represent a proportional relationship because the line don't passes through the origin

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form k=\frac{y}{x} or y=kx

In a proportional relationship the constant of proportionality k is equal to the slope m of the line <u><em>and the line passes through the origin</em></u>

so

In this problem we have

y=3x+5

This is the equation of the line in slope intercept form

where

the slope is m=5

the y-intercept is b=5

Remember that in a proportional relationship the value of b must be equal to zero (because the line passes through the origin)

therefore

The equation not represent a proportional relationship because the line don't passes through the origin

NEED HELP FAST!!!! will mark u as brainliest
Shalnov [3]
Obviously, it's not rational, because it's the sum of two square roots, so cancel out A and B right away.

If we solve it
 
sqrt (18) + sqrt (2)
= sqrt (9*2) + sqrt (2)
= 3 sqrt (2) + sqrt (2)
= 4 sqrt (2)
