= $118.50

To find the change

$200.00

- $118.50

= $81.50

Write in standard form: a line through the origin with slope 2/3

nordsb [41]

Answer:

y = 2/3x

Step-by-step explanation:

Slope-intercept formula: y = mx + b

m = 2/3 because the slope is 2/3.

b = 0 because the y value of the origin is 0, as the point is at (0, 0).

That makes y = 2/3x + 0, but adding zero does nothing so you take it out to get y = 2/3x.

Is (-5, 8)a solution for y-2x>17?

Gnoma [55]

You can plug in the numbers to check.
Y - 2x > 17
(8) -2(-5) > 17
8 + 10 > 17
18 > 17
This is true so
Final answer:
Yes, (-5,8) is a solution

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

Step-by-step explanation:

Step 1: Define

Point (-5, -2) → x₁ = -5, y₁ = -2

Point (-3, 4) → x₂ = -3, y₂ = 4

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(-3+5)^2+(4+2)^2}$
[√Radical] (Parenthesis) Add: $\displaystyle d = \sqrt{(2)^2+(6)^2}$
[√Radical] Evaluate exponents: $\displaystyle d = \sqrt{4+36}$
[√Radical] Add: $\displaystyle d = \sqrt{40}$
[√Radical] Simplify: $\displaystyle d = 2\sqrt{10}$
