-3.75+2(-4x+6.1)-3.25

Pani-rosa [81]

The value of x is 0.65

Step-by-step explanation:

This solution is given by solving the given problem using BODMAS rule.

This means that the steps to be followed to find the solution should be in the order of BODMAS rule.

B- Bracket, O- of, D- Division, M- Multiplication, A- Addition, S- Subtraction.

This rule states that the 1st operation must be done for Brackets.

⇒ -3.75+2(-4x+6.1)-3.25 = 0

⇒ -3.75 -8x + 12.2 -3.25 = 0

The addition operation should be performed next and then followed by subtraction.

⇒ -8x -7+ 12.2 = 0

To find the value of x :

Keeping the x term alone on one side and moving the constants on other side,

⇒ -8x = -12.2 + 7

⇒ -8x = -5.2

⇒ x = 5.2/8

⇒ x = 0.65

Question 6 Find the slope of the line passing through the points (11,-5) and (11,6)

zimovet [89]

There are two ways to approach this.

Option #1:

Use the slope formula $m = \dfrac{y_2-y_1}{x_2-x_1}$ .

$m= \dfrac{6-(-5)}{11-11} = \dfrac{11}{0}$

That value is undefined, so the slope is undefined.

Option #2:

Because the two points have the same x-value, they will be vertically above/below one another. This means your line is a vertical line and the slope of a vertical line is undefined.

Either way, your slope is undefined.
