Y + 3 = 4(x - 5)
y + 3 = 4x - 20
y = 4x - 20 - 3
y = 4x - 23
Answer:
Step-by-step explanation:
A) The dealer bought Birr 8000 at 7% tax.
Total amount to be paid = cost price (1 + r%)
r = 7% = 0.07
Total amount to be paid 
B) To find the VAT, it is the difference between the tax paid when the good was bought and the tax put on it after it was sold.
Tax paid when the shoes were bought = 7% of cost price
Tax paid when the shoes were sold = 9% of selling price
VAT = tax recovered on sale - Tax paid on purchase
Answer:

Step-by-step explanation:
20% times 5 = 100%
6 in every 20%
since there is 5 20%'s, multiply 6 times 5 and you get 30
Answer:
7/6
Step-by-step explanation:
In order to find slope when you have two ordered pairs, you use this equation: (y2-y1)/(x2-x1)
In this case, when you plug them in, you get (49-7)/(42-6), which is 42/36, which is 7/6.
Hope this helped :)
Inverse variation is of the form:
y=k/x, which we can express as:
yx=k we are given the point (2/3, 7) so we can solve for k
7(2/3)=k
14/3=k
y=14/(3x), so when x=7/3
y=(14/3)/(7/3)
y=(14/3)(3/7)
y=2
