It's probably not right

Step-by-step explanation:

Simplifying

13x + 6y = 180

Solving

13x + 6y = 180

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-6y' to each side of the equation.

13x + 6y + -6y = 180 + -6y

Combine like terms: 6y + -6y = 0

13x + 0 = 180 + -6y

13x = 180 + -6y

Divide each side by '13'.

x = 13.84615385 + -0.4615384615y

Simplifying

x = 13.84615385 + -0.4615384615y

Answer:

  -10

Step-by-step explanation:

Solving for y gives ...

  20y = 2x +6

  y = 2/20x +6/20 = 1/10x +3/10

The slope of the given line is the coefficient of x: 1/10. The slope of the perpendicular line is the opposite reciprocal of this: -1/(1/10) = -10.

The perpendicular line has a slope of -10.

An appropriate cautious reading of a receipt entail making sure that the

items charged are the same as the items received and checking to see if all

of the discounts were applied properly,

When an item is bought, a receipt is usually issued which confirms that

payment has been made for the goods or services. Receipt however should

be properly checked to detect any error in the course of the transaction.

Making sure that the items charged are the same as the items received and

checking to see if all of the discounts were applied properly should be done

to avoid shortages of the resources of the parties involved.

Step-by-step explanation:

The value -105 is the coefficient of x.

The slope is most easily read from the equation when it is in slope-intercept form. In that form, the slope is the coefficient of x. You could say Kim forgot to write the equation in slope-intercept form.

When the equation is written in that form, it becomes ...

  165 -105x +3y = 0

  165 -105x = -3y . . . . subtract 3y

  -55 +35x = y . . . . . . divide by -3

  y = 35x -55 . . . . . . in slope-intercept form

The correct slope is 35.

Answer:

Step-by-step explanation:

I am un-sure of the answers. I apologize if this is incorrect.

Hoped this helped.

Here,

(-1, 4) = (x₁ , y₁)

(-6, -5) = (x₂ , y₂)

Slope = rise/run

Slope = y₂ - y₁/x₂ - x₁

Slope = -5 - 4/ -6 + 1

Slope = -9/-5

Slope = 9/5

  (c)  y -2 = 6/5(x -1)

Step-by-step explanation:

The equations are all in point-slope form with a slope of 6/5. The points used are (-1, -2), (-2, -1), and (1, 2). It seems point (1, 2) best matches a point on the graphed line. Choice C is the best. (In the attached graph, choice C is the red line.)

Answer:

[tex]\frac{5}{6}[/tex]

Step-by-step explanation:

In order to find the answer, you need to use the slope formula, substitute, subtract, and simplify if needed.

Slope formula = [tex]\frac{y^2-y^1}{x^2-x^1}[/tex]

[tex]\frac{y^2-y^1}{x^2-x^1}=\frac{8-3}{9-3}[/tex]

[tex]8-3 = 5[/tex]

[tex]9-3 = 6[/tex]

= [tex]\frac{5}{6}[/tex]

Answer:

y=24

Step-by-step explanation:

since the triangles are similar, their sides are all in proportion

meaning:

[tex] \frac{20}{15} = \frac{32}{y} [/tex]

simplify the fraction

[tex] \frac{4}{3} = \frac{32}{y} [/tex]

cross multiply once the fraction is simplified

[tex]96 = 4y[/tex]

y=24

Answer:

y = 24

Step-by-step explanation:

the first triangle 20 : x : 32

the 2nd triangle 15 : 21 : y

Solve the equation of two triangles by similarity

x = [tex]\frac{21 * 20}{15}[/tex] = 28

y = [tex]\frac{21 * 32}{28}[/tex] = 24

Step-by-step explanation:

Answer:

n = 20

Step-by-step explanation:

n + 1/5 n = 24

n + n/5 = 24

LCM = 5

5n/5 + n/5 = 24

( 5n + n )/5 = 24

5n + n = 5 x 24

6n = 120

n = 120 / 6

n = 20

Answer:

27.5

Step-by-step explanation:

Answer:

n = -5

Step-by-step explanation:

-6(-5n+3)+2=-166

distribute the -6

- 6 * -5n = 30n

-6 * 3 = - 18

30n - 18 + 2 = -166

combine like terms

30n - 16 = -166

add 16 to both sides

30n = -150

divide both sides by 30

30n/30=n

-150/30=-5

we're left with n = -5
