Find the equation of the perpendicular line to 2x-5y-10=0 and containing point (-1,5)

Answers

Answer 1

Answer:

y = -2.5x + 2.5

Step-by-step explanation:

Put the equation into y = mx + b form by isolating y:

2x - 5y - 10 = 0

2x - 5y = 10

-5y = -2x + 10

y = 2/5x - 2

Perpendicular lines have opposite reciprocal slopes, so the line's slope will be -5/2, or -2.5

Plug in the slope and given point into y = mx + b, and solve for b:

y = mx + b

5 = -2.5(-1) + b

5 = 2.5 + b

2.5 = b

Plug in the slope and y intercept:

y = mx + b

y = -2.5x + 2.5 is the equation of the perpendicular line

Alia has a AED 20 gift card for an online music store. All songs at the store have the same price. After Alia buys 3 songs, the balance on the card is AED 16.25. What will be the remaining balance on the card after he buys 5 more songs

Answers

Answer:

Remaining balance = AED 13.75

Step-by-step explanation:

Given that:

Amount of gift card = AED 20

Amount left after buying 3 songs = AED 16.25

Cost of 3 songs = 20 - 16.25 = AED 3.75

Cost per song = [tex]\frac{3.75}{3}[/tex]

Cost per song = AED 1.25

Cost of 5 songs = 5(1.25) = AED 6.25

Remaining balance = 20 - 6.25 = AED 13.75

Hence,

Remaining balance = AED 13.75

3 .912+s=5.313 evaluate

Answers

Answer:

s= 1.401

Step-by-step explanation:

subtract 5.313 from 3.912 :D

The evaluation of the equation 3 .912+s=5.313 yields; s = 1.401

Evaluation of one variable equation

According to the questions;

We are required to evaluate the equation; 3 .912+s=5.313

Hence, we must subtract 3.912 from both sides of the equation as follows;

3 .912+s -3.912 = 5.313 - 3.912.

s = 1.401

Trigonometric Ratios

The ratios of the sides of a right triangle are called trigonometric ratios.

The longest side of the triangle is called the hypotenuse and the other two sides are the legs.

The sine ratio relates the opposite side of an angle of the triangle with the hypotenuse:

[tex]\displaystyle \sin B=\frac{\text{opposite leg}}{\text{hypotenuse}}[/tex]

Here, the opposite leg to angle B is the side CA=2, and the hypotenuse is the side AB=3, thus:

[tex]\displaystyle \sin \angle B=\frac{2}{3}=0.667[/tex]

Calculating the inverse sine function:

[tex]\angle B=\arcsin (0.667)[/tex]

[tex]\boxed{\angle B=41.81^\circ}[/tex]

an account executive earns 600 per month plus 3% commission on sales. the executive's goal is to earn $2400 this month. how much must she sell to achieve this goal?

Answers

Answer:

$60,000

Step-by-step explanation:

Given :

Monthly earning = $600

Commission = 3%

Month's goal = $2400

Let total sales for the month = x

Hence,

Monthly earning + (commission * total sales) = monthly goal

600 + (0.03 * x) = 2400

600 + 0.03x = 2400

0.03x = 2400 - 600

0.03x = 1800

x = 1800 / 0.03

x = $60,000

Answer:

  (x, y) = (1, 8)

Step-by-step explanation:

A graphing calculator quickly tells you the point of intersection.

You can equate the y-values and solve for x.

  3x +5 = -2x +10

  5x = 5 . . . . . . . . . add 2x-5

  x = 1 . . . . . . . divide by 5

  3·1 +5 = y = 8 . . . . substitute for x in the first equation
