Answer:

Yes; 2/3

Step-by-step explanation:

The rate of change is 2/3 because from the first dot to the next, it moves up two and to the right 3. This is a linear relationship because the rate of change is constant, meaning it never changes.

Find the value of x<br><br>urgent!! plz help me! will give the brainliest

Answer:

x = 2

Step-by-step explanation:

$\frac{1}{2} (x - 1) - \frac{1}{6} (x+1) = 0$

In an equation our aim is to find the value of what we are looking for as well as keeping the equation balanced. For example if we divided by 2 only from one side then the equation would change so it's an important rule to keep in mind when solving equations, that you need to keep both sides of the equation the same.

$\frac{1}{2} (x - 1) - \frac{1}{6} (x+1) = 0$

→ Expand the brackets

$\frac{1}{2} x- \frac{1}{2}-\frac{1}{6}x -\frac{1}{6} =0$

→ Multiply everything by 12 to make solving the equation easier

6x - 6 - 2x - 2 = 0

→ Simplify equation

4x - 8 = 0

→ Add 8 to both sides to isolate 4x

4x = 8

→ Divide by 4 on both sides to isolate x

x = 2

⇒ We can substitute x = 2 back into the equation to see if the solution is correct, if we get 0 on both sides then x = 2 is correct

$\frac{1}{2} (x - 1) - \frac{1}{6} (x+1) = 0$

⇒ Substitute in the values

$\frac{1}{2} (2-1)-\frac{1}{6} (2+1) = 0$

⇒ Simplify

$\frac{1}{2} (1)-\frac{1}{6} (3) = 0$

⇒ Simplify further

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

0 = 0

The solution x = 2 is correct

Which is equivalent?

olga_2 [115]

Answer:

Step-by-step explanation:

Given

$\frac{x}{\sqrt{2} }$

Multiply numerator/ denominator by $\sqrt{2}$ to rationalise the denominator

= $\frac{x\sqrt{2} }{\sqrt{2}(\sqrt{2}) }$

= $\frac{x\sqrt{2} }{2}$ → A

The merry-go-round in the elementary playground can hold no more than 12 students at a time. Write the inequality for this scena

gulaghasi [49]

If x=students, the equation would be x=12 (x is less than of equal to twelve). I don’t know what you mean by constraints; perhaps if you explain more, I could help?

HELP PLEASEEEEEE!!!! CAN YOU GIVE ME STEPS TOO??<br> I'd really appreciate some help.

Neko [114]

This line has an undefined slope. This means that there is only a rise not a run

The x values stay the same no matter the y value.

This means that the equation is:

x = 3

Hope this helped!
