If 3x - 8= -2, find the value of x - 6.

siniylev [52]

Answer:

x-6 = -4

Step-by-step explanation:

3x - 8= -2

Add 8 to each side

3x - 8+8= -2+8

3x = 6

Divide by 3

3x/3 = 6/2

x =2

We want to find x-6

2-6 = -4

Calculate the gradient of the line using rise/run method.

Lapatulllka [165]

Given:

The graph of line.

To find:

The gradient of the line using rise/run method.

Solution:

We know that the gradient of a line is also known as slope.

$Slope=\dfrac{Rise}{Run}$

Consider the two intercepts, then rise is distance between origin and y-intercept and run is the distance between origin and the x-intercept. But rise must be negative because the value of y decreased from 3 to 0.

$Rise=-3$

$Run=2$

Now,

$Slope=\dfrac{Rise}{Run}$

$Slope=\dfrac{-3}{2}$

The gradient of the line is $-\dfrac{3}{2}$ .

Therefore, the correct option is C.

What is x in this equation −4.5= −0.5(x − 7.1)

Umnica [9.8K]

Answer:

x=16.1

Step-by-step explanation:

$-4.5= -0.5(x -7.1)$

Divide both sides by -0.5

$9=x-7.1$

Add 7.1 to both sides

$16.1=x$

Hope this helps!

Which of these choices show a pair of equivalent expressions?

NISA [10]

Answer:

A. 6^2/7 and (√6)^7

Step-by-step explanation:

Because we can't get 6 out of root as a whole we need to use the power to show its value when we do so.

The power of (√6)^7 has is seven and degree of the root is 2 so we have to put 2/7 over 6 when we take it out of root.
