Both slopes have the same value which is 7.5.
To compute for the slope we will use this formula:
m = y^2 - y^1 over x^2 - x^1
For the first slope, the points are<span> (4, 30) and (12, 90). Substitute and simplify.
m = (90 - 30) over (12 - 4)
m = 7.5
For the second slope, the points are </span><span>(4, 30) and (10, 75). Same with the above computation.
m = (75 - 30) over (10 - 4)
m = 7.5
Since the relationship is linear, the slope does not change. </span>
Answer:
$178.3
Step-by-step explanation:
The value of a car is $20,000
The car loses 10.7% of its value yearly
Since there are 12 months in a year then 10.7% can be represented as
10.7%/12
= 0.8916%
Therefore the approximate monthly decrease in value can be calculated as follows
= $20,000×0.8916/100
= $20,000×0.008916
= $178.3
Hence the approximate monthly decrease in value is $178.3
Given:
Henrietta budget: 120
Original Price of the bike : 150
discount: 20%
sales tax: 6%
150 * 20% = 30
150 - 30 = 120 discounted price
120 * 6% = 7.2 sales tax
120 + 7.2 = 127.20 total cost of the bike
Since Henrietta only has 120, A.) Henrietta has enough before the tax, but not enough after the tax.
AD = 6·3 = 18 in.
AM = AB/2 = 6/2 = 3 in.
DN = CD/2 = 6/2 = 3in.
MN = AD - (AM+DN) = 18 - (3+3) =
12 in.
