Most of the graphing resources used shows that the graph is translated up by 3.25 (3 + 1/4). If you add the 3 and the 1/4, you get the equation of a line:
f(x) = x + 3.25,
which means that the graph of f(x)= x now has a y intercept of 3.25.
The graphs are below. The red line represents f(x) = x, and the green line represents (x+3)+1/4. Hope this helps!
Im sorry wish i could help but the equation is a little confusing give me a few moments and i will figure out the answer okay?
Okay, i don't want to give you the direct answer because i want you to know how to do it ... First you multuply $4.30 x .4 and you will get a number... remember that number in your head and subtract it from the original amount of $4.30... then once you get the number from subtracting the discount, multiply that number by .6..... then with that number, add the sales tax and there is your answer!
Answer:
The first one is the answer to the question
equation has infinitely many solutions has the same number on both sides of the equal sign
-3x -21 + x + 5 = -20x -16
-2x -16 = -20x -16
so either you have -18x on the left or +18x in the right
