Answer:

y=-7x -2

Step-by-step explanation:

use formula to find the equation when you know slope and a point

it is: y-y1 = m(x-x1)

plug in values

y-(-30) = -7(x-4)

y+30 = -7x + 28

- 30 from both sides

y = -7x -2

When an article is sold for Rs 23, there is profit.
Svet_ta [14]

Answer:

Cost price = R.S 20

Sales price = R.S 22

Step-by-step explanation:

Given:

Sales price of an article = R.S 23

Profit = 15%

Find:

Cost price

Sales price if profit is 10%

Computation:

Profit% = [(Sales price - Cost price) / Cost price]100

15 = [(23-cp)/cp]100

15cp = 2,300 - 100cp

115cp = 2,300

Cost price = R.S 20

Sales price if profit is 10%

Sales price = Cost price + Profit

Sales price = 20 + 10%[20]

Sales price = 20 + 2

Sales price = R.S 22

A long string with a balloon at the end was tied to the ground. After a breeze came up, the balloon was 55 feet to the right of
Alexxx [7]

Answer:

<em>The slope is 0.55</em>

Step-by-step explanation:

<u>Right Triangles</u>

The string, the ground, and the height of the balloon form a right triangle where the trigonometric ratios are satisfied.

The image below shows the geometric construction. We are required to find the slope the string forms with the ground.

It can be found by using the tangent ratio:

\displaystyle \tan\theta=\frac{y}{x}

Substituting y=30 and x=55

\displaystyle \tan\theta=\frac{30}{55}

\displaystyle \tan\theta=0.55

The slope is 0.55

-2(3x-1)&lt;8 on a number line
Veronika [31]

Answer:

Checkout the image below the explanation.

Step-by-step explanation:

1. First, let's solve the inequality.

Step 1: Simplify both sides of the inequality.

  • -6x + 2 < 8

Step 2: Subtract 2 from both sides.

  • -6x + 2 - 2 < 8 - 2
  • -6x < 6

Step 3: Divide both sides by -6 and flip the sign.

  • \frac{-6x}{-6}  < \frac{6}{-6}
  • x > -1

2. Now that we solved the inequality and got x > -1, that means that all values of x are more than -1. It can be represented on the number-line as this:
