Step-by-step explanation:
<u>Equation of line k</u>
- y = mx + b
- m = Δy/Δx (ratio of change in y to change in x) = 2/3
- b = 3 (as y-intercept is [0,3])
- ⇒ y = 2/3x + 3
<u />
<u>a. parallel line</u>
- For parallel lines, slope (m) remains the same, but the y-intercept (b) changes
- ⇒ <u>y = 2/3x + 1</u>
<u></u>
<u>b. perpendicular line</u>
- For perpendicular lines, the slope (m) is the negative reciprocal of the original line and the value of b stays the same [it can be any point as long as it intersects the line]
- ⇒ <u>y = -3/2x + 1</u>
<span>We can represent the number of pies she makes to be x.
We also need to add $30 to the equation to take the baking supply cost into consideration.
The Cost can be represented by C.
C = 5x + 30 is the equation to use to determine the Cost! 5 times the number of pies she makes plus the $30 for baking supplies!
If we look at just the cost when she doesn't sell any pies, we can say x = 0
That means C = 5(0) + 30 or C = 30, it means that she has to pay $30 or the Cost is $30 when she sells no pies.
This makes sense since the baking supplies were $30.
Are you with me so far?</span>
6 feet * 7 feet = 42 feet²
18 feet * 21 feet = 378 feet²
42 feet² was painted for $52
1 feet² will be painted for $52/42
378 feet² will then be painted for: ($52/42) * 378
= $468
Hence 18 feet by 21 feet will be painted for $468
Hope this helps.
