The function represented by the table is linear function
and pass with (0,0)
so it is in the form
f(x) = m x
where m is the slope
m = [ f(x₂) - f (x₁) ] / [ x₂ -x₁]
(4-0)/(1-0) =4
so
f(x) = 4 x
Answer:
A, B, D are equations representing a linear function
Step-by-step explanation:
All linear functions have an equation like the following: y=mx+b, where m is the slope and b is an offset.
A. y=x-4, m=1 and b=-4
B. y=x+4, m=1 and b=4
D. y=x+7, m=1 and b=7
The third eq dont behave like a linear function since there is quadratic term on one side of the equation, this is not a linear function
<span><u><em>The correct answer is:</em></u>
$42.
<u><em>Explanation:</em></u>
The best way to find a total bill including tip (or tax if that is what you are looking for - it is found the same way), is to multiply the original total by 1 + the percentage of the tip.
Since the percentage is 20%, we add 0.20 to 1 to get 1.20.
Now we multiply that by the original cost to get the final answer.
1.20*35 = 42</span>
Well if you make $7.25 an hour and work four hours then multiply
7.25 x 4 = 29
so you make $29 a day and you work fro 5 days multiply the amount and the days which is
29 x 5 = 125
so you make $125 dollars after working 4 hours a day for 5 days
