Answer:
The watermelon costs $4.45
Step-by-step explanation:
Hi there!
Let´s define the variables:
x = cost of the watermelon.
y = cost of the napkins.
z = cost of the paper plates.
We know that the sum of the 3 items costs 8.25 without taxes. Then:
x + y + z = 8.25
We also know that he paid 0.19 in total taxes and that the only items taxed at 5% are the napkins (y) and the paper plates (z). Then, 5% of the cost of the napkins plus 5% of the cost of the plates is 0.19:
0.05 y + 0.05 z = 0.19
If we divide both sides of this equation by 0.05, we will obtain:
y + z = 0.19/0.05
y + z = 3.8
Then, let´s replace y + z = 3.8 in the first equation and solve it for x:
x + y + z = 8.25 (y + z = 3.8)
x + 3.8 = 8.25
subtract 3.8 to both sides of the equation:
x = 4.45
The watermelon costs $4.45
Have a nice day!

Answer:
2 if x=0
Step-by-step explanation:
A function is an equation that has only one answer for y for every x. A function assigns exactly one output to each input of a specified type.
f(x) = 10x + 2
Replacing f(x) with y
y = 10x + 2
If x = 2,
y = 10(0)+2
y=2
