3x + 4y= 16 solve for y

1 answer:

5 0

3x + 4y = 16
<u>- 3x -3x</u>
4y = -3x + 16 (divide each side by 4)
$\frac{4y}{4} = \frac{-3x+16}{4}$
y = -3/4x + 16/4

The answer is $y =- \frac{3}{4}x +4$

Complete Question

A cylindrical vase has a diameter of 6 inches. At the bottom of the vase, there are 7 marbles, each of diameter 3 inches. The vase is filled with water up to a height of 12 inches.Which of the Following could be used to calculate the volume of water in the vase?

Answer:

$V_w= \pi (3)^2(12) - 8(4/3) \pi(1.5)^3$

Step-by-step explanation:

From the question we are told that:

Diameter of vase $d=6$

Number of marbles $n_m=7$

Diameter of marbles $d_m=3 inch$

Height of water $h_w=12$

Generally the equation for Volume of water in cylindrical vase $V_w$ is mathematically given by

$V_w= \pi r^2h - Volume \, of \, the\, balls$

Where Volume of the balls $V_b$ is

$V_b= 7(4/3) \pi r^3\\\\V_b= 7(4/3) \pi (1.5)^3$

Therefore

$V_w= \pi r^2h - Volume \, of \, the\, balls$

$V_w= \pi (3)^2(12) - 8(4/3) \pi(1.5)^3$

There is more than 1 way to do this but the way i use is to go back to zero and move that amount of spaces to left if the original integer is positive or to the right if the original integer is a negative
