I'm not 100% sure what you want me to do with this but i hope this helps:

x < -3

or if you want me to flip the sign then the solution becomes

x > -3

$\text {Hi!}$

$\text {The Answer to this Problem Is:}$

$\fbox {True!}$

$\text {When we look at a number line with positive and negative numbers we see}$ $\text {that positives are to the right and negatives are to the left.}$

$\text {As you can see the number line on the image that all}$ $\text {the negative numbers are to the left and positive numbers are to the right.}$

$\text {\underline {Remember}}$

$\text {Positive to the Right.}$

$\text {Negative to the Left.}$

Express the following equation in slope-intercept form: 13x - 3y = 18 Select the best answer from the choices provided. A. y = 3

AveGali [126]

Answer:

The equation in the slope-intercept form is y = $\frac{13}{3}x$ + -6 ⇒ C

Step-by-step explanation:

The slope-intercept form of the linear equation is

y = m x + b, where

m is the slope of the line

b is the y-intercept

∵ The equation is 13x - 3y = 18

→ At first move x from the left side to the right side by subtracting 13x

from both sides

∴ 13x - 13x - 3y = 18 - 13x

∴ - 3y = 18 - 13x

→ Make the coefficient of y equal 1 by dividing both sides by -3

∵ $\frac{-3y}{-3}=\frac{18}{-3}-\frac{13x}{-3}$

∴ y = -6 - ( $-\frac{13}{3}x$ )

→ Remember (-)(-) = (+)

∴ y = -6 + $\frac{13}{3}x$

→ Switch the two terms of the right side

∴ y = $\frac{13}{3}x$ + - 6

∴ The equation in the slope-intercept form is y = $\frac{13}{3}x$ + -6

Determine if each set of ordered pairs represents a function. <br> (2,3), (6,-5), (-1,3)

docker41 [41]

Answer:

yes

Step-by-step explanation:

You can perform the "line test." If it is a function, there will not be two x's of the same value. In this case, x is 2,6,-1. No number repeats, thus making a function.

First one that gets it correctly gets branlyest

sasho [114]

Answer:

200 in2

Step-by-step explanation:

diameter= 15 in. so raduis = 15/2

area of circle = πr2

= 22/7 * 15/2 *15/2

= 176.79

rounding to the nearest 100, its 200 in2
