i had a test with the same question, i promise its right :)
I think if 10% and $8 off an item together would be good for an more expensive item life $ 20-50 I think 15% off would be better for an less expensive item like $1-10
We all are familiar with (x,y) coordinate plane where some lines or curves are drawn. These curves are drawn or made up using some (x,y) points. These values of (x,y) points satisfy the equation of curves.
The equation of x and y variables is called a Relationship. Now, a Function is a "special relationship of x and y variables" where each input x has a single answer for output y.
In other words, we can say any relation y=f(x) would be a "Function" if and only if each value of x input give us a unique value of y output from the equation. No two values of y can be output of same x-value input.
For example:- y = f(x) = 2x is a Function because each value of x would give unique answer for y. x=4 gives y=8.
Another example is:- y = f(x) = √x is "not a function" because one-value of x would give two answers of y. x=4 gives y= -2 and y=2.
Answer:
a. 70 miles per hour
b. 840 miles
Step-by-step explanation:
280/4 = 70 miles per hour
70*12 = 840 miles
