Based on the given data we could derive an equation that will express the statement as, Income (i) = 20h + 40. That was express that way since it says that thre is already a 40 dollars charge for inspection, so it is a constant variable. Then it will be added to the product of number of hours times 20 dollars per hour.
Answer:
x^2 + y^2 = 10.
Step-by-step explanation:
The square of the radius is (-1)^2 + (-3)^2 = 1 + 9
= 10.
The general form is x^2 + y^2 = r^2
so here it is x^2 + y^2 = 10.
Answer:
Length = 42, Width = 25
Step-by-step explanation:
You write out the equation for the length, which is L=2w-8 (Length is L and width is W) You substitute in the length in the original equation, 2L + 2W = 134 ( I got this equation from knowing that 2 lengths plus 2 widths equals the perimeter, 134.) Substitute 2w-8 for L, you're left with 2(2w-8) + 2w = 134. Simplify further, you have 4w-16+2w=134. Once you're done, you have W=25. Plug that back into the original equation, then solve. L = 2(25)-8, L=42.
For the 3 you multiply the equations of f(x) and g(x) by each other and you do that by foiling then you combine like terms. After that the terms A, B,C D, and E are in the answer which is...
s= original price of shoes
n= new price of shoes
s+0.05s=n
