The y-intercept is found when x is set to 0.
Set x to equal 0 for both equations:


Divide both sides by -2:

The y-intercept of this equation is 3, so the first line does not have the y-intercept of -2.
-


Divide both sides by 2:

The y-intercept of this equation is -1, so the second line does not have the y-intercept of -2.
Neither line has a y-intercept of -2.
100% = 24000
50 % = 12000
10% = 2400
5 % = 1200
1 % = 240
Answer:
$2.04
Step-by-step explanation:
Note that: 1 yard = 3 feet.
First, change the amount of yard (6) to feet:
6 x 3 = 18
6 yard = 18 feet.
Note: 18 feet = $36.72
Find the cost per foot (1 feet). Note the equal sign, what you do to one side, you do to the other. Divide 18 from both sides.
(18 ft)/18 = ($36.72)/18
1 ft = 36.72/18
1 ft = 2.04/1
1 ft = $2.04

- sin∅ = opposite over hypotenuse
Step-by-step explanation:
<u>Step 1: Define</u>
∅ = 40°
opposite leg of angle = 50 ft
hypotenuse = x ft
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute: sin40° = 50/x
- Multiply <em>x </em>on both sides: xsin40° = 50
- Divide sin40° on both sides: x = 50/sin40°
- Evaluate: x = 77.7862
- Round: x = 77.8 ft
