Answer:
45+10x = y
Step-by-step explanation:
$45 -- stays the same no matter what so that's constant.
$10 -- this varies dependent on the number of vaccinations your dog needs, so you'd use a variable to represent the number of vaccinations (in this case I'm using variable "x").
So, for example if your dog needed 7 vaccinations, it would be: 45+10(7) = y -- answer being $115.

Answer:
x=6
Step-by-step explanation:
2 (x-4) +3 =7
Subtract 3 from each side
2 (x-4) +3-3 =7-3
2(x-4) =4
Divide each side by 2
2(x-4)/2 = 4/2
x-4 = 2
Add 4 to each side
x-4+4 =2+4
x=6
We know that for √x to be meaningful, we must have x ≥ 0.
If we square both sides of the inequality, we have
x < 4²
x < 16
Thus the whole solution is
0 ≤ x < 16
The following choices are valid solutions to the inequality:
B. 12
C. 2
E. 5
Answer:
43.5 % decrease
Step-by-step explanation:
Take the original price and subtract the new price
850-480
370
Divide by the original price
370/850
.435294118
Change to percent form by multiplying by 100
43.5294118 % decrease
43.5 % decrease
