Answer:

y = 3x -5

Step-by-step explanation:

y = mx + b

for (5, 10)

b = y - mx = 10 - 3 x 5 = - 5

y = 3x -5

Answer:

A) 113 m²

Step-by-step explanation:

Use the formula for area of a circle.

Area of a circle = πr²

π = pi = 3.14 (rounded)

r = radius

² = the power of 2, or the radius (in this case) multiplied by itself.

Note that the radius is given, and it is 6. Plug in 6 for the radius:

A (circle) = π(6)²

First, solve the power. Multiply 6²:

6² = 6 * 6 = 36

Next, multiply 36 with π (3.14):

36 x 3.14 = 113.04

A) 113 m² is your closest answer.

Two years ago, Sally had 5,000 dogs in her dog shelter. Now she has 24,575 dogs. The rate of change is 391.5 % increase

<em><u>Solution:</u></em>

Given that Two years ago, Sally had 5,000 dogs in her dog shelter

Now she has 24,575 dogs

To find: rate of change

A rate of change is a rate that describes how one quantity changes in relation to another quantity

<h3><u>Steps to follow:</u></h3>
  • First: work out the difference (increase) between the two numbers you are comparing.
  • Increase = New Number - Original Number.
  • Then: divide the increase by the original number and multiply the answer by 100.
  • % change = Increase ÷ Original Number x 100

\text {rate of change }=\frac{\text { new value }-\text {original value}}{\text {original value}} \times 100

\begin{array}{l}{\text { rate of change }=\frac{24,575-5000}{5000} \times 100} \\\\ {\text { rate of change }=\frac{19575}{5000} \times 100=391.5}\end{array}

Thus the rate of change is 391.5 % increase
