Answer:
hope it helps...
Step-by-step explanation:
The ratio of a number x and four added to two:
= 4x + 2 = 0
= 4x = -2
= 4x/4 = -2/4
= x = -2/4
= x = -1/2
What exactly do you need to find? Does it need simplified?
Answer:
Infinite many solutions - all are correct
Step-by-step explanation:
Since f(x) and g(x) are the same function, their graphs will be the same and all points on the line are solutions. All x values will be solutions. This means there are infinitely many.
You can see it algebraically too:
-2x-6 = -2x-6
-2x+2x-6 = -2x +2x -6
0-6 = 0-6
-6=-6 True. Infinite solutions.
Answer:
$5.40
Step-by-step explanation:
First, figure out the cost of the items with tax; for Tommy we have 20*0.08 = 1.6, add that 1.6 to the 20 and his purchase is $21.6, for John we have 25*0.08 = 2, add 2 to his 25 and his purchase is $27. To find the difference we subtract 27-21.6 = 5.4 or $5.40
