Distance Formula: $d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

<u>Step 1: Define</u>

Point A (2, 4)

Point B (3, 6)

<u>Step 2: Find distance </u><em><u>d</u></em>

Substitute: $d = \sqrt{(3-2)^2+(6-4)^2}$
Subtract: $d = \sqrt{(1)^2+(2)^2}$
Exponents: $d = \sqrt{1+4}$

Joshua currently does a total of 8 pushups each day. He plans to increase the number of pushups he does each day by 2 pushups un

Maslowich

Answer:

x=12

Step-by-step explanation:

Let y equal number of pushups a day. When x = 1, y = 8. When x = 2, y = 10. 10 is a factor of 30. Multiply y by 3. However, since x increases by 1 when y increases by 2, multiply x by 6 (2*3). That equals 12. Therefore, when x = 12, y = 30.
