![4y + 3y](https://tex.z-dn.net/?f=4y%20%2B%203y)
<h3>Solution:</h3>
![4y + 3y \\ = 7y](https://tex.z-dn.net/?f=4y%20%2B%203y%20%5C%5C%20%20%3D%207y)
- Adding the numerical coefficient with the terms that have the same variables. Meaning they are like terms. Adding the base and then copy the variables.
<h3>> Therefore, the answer is 7y.</h3>
Answer:
y = 0.87x + 0.02
Step-by-step explanation:
Euros as a function of dollars means that euros is y and dollars are x.
We are given 2 points: (4, 3.5) and (10, 8.72)
slope = (8.72 - 3.5)/(10 - 4)
slope = 5.22/6 = 0.87
y = 0.87x + b
3.5 = 0.87(4) + b
b = 0.02
y = 0.87x + 0.02

mathematicallly error sentence!
Volume of the cylinder=area (circle) x height
area (circle)=πr²
r=radius=4 in.
area=π(4 in)²=16π in²
height=8 in
Volume of the cylinder=(16π in²)(8 in)=128π in³≈402.12 in³
Answer= 128π in³ or 402.12 in³
