elimination of x:

-6x +5y = 1

6x + 4y = -10

___________+

9y = -9

y = -9/9 = -1

elimination of y:

-24x +20y = 4

30x + 20y = -50

_____________-

-54x = 54

x = 54/-54 = -1

\huge{ \mathcal{  \underline{ Answer }\:  \:  ✓ }}

The given equations are :

\longrightarrow - 6x + 5y = 1

\longrightarrow6x + 4y =  - 10

let's add the equations

\longrightarrow\small{ - 6x + 5y +6x + 4y =  1  + ( - 10)}

\longrightarrow9y =  - 9

\longrightarrow y =  - 1

now, let's plug the value of y in first equation :

\longrightarrow - 6x + (5 \times  - 1) = 1

\longrightarrow - 6x  - 5 = 1

\longrightarrow - 6x = 6

\longrightarrow x =  - 1

An oil tank has to be drained for maintenance. The tank is shaped like a cylinder that is 4 ft long with a diameter of 2.2 ft. S
gavmur [86]

Answer:

8\:\mathrm{minutes}

Step-by-step explanation:

The volume of a cylinder is given as:

r^2\cdot\pi\cdot h

Since the diameter is 2.2, the radius is \frac{2.2}{2}=1.1.

Therefore, the volume of this cylinder is:

1.1^2\cdot 3.14\cdot 4=15.1976\:\mathrm{ft^3}, using \pi=3.14 as requested in the problem.

Since the tank is emptied at a constant rate of 1.5\:\mathrm{ft^3\:per\:minute}, it will take

\frac{15.1976}{1.5}=7.5988=\fbox{$8\:\mathrm{minutes}$} to empty the tank.

What is the rate of change for 2y+3=3x
Elenna [48]
The rate of change in z at (4,9) as we change x but hold y fixed is = 3/[2sqrt(3x+2y)] put x = 4 , y = 9 = 3/[2sqrt(12+18) = 3/[2sqrt(30)] The rate of change in z at (4,9) as we change y but hold x fixed is = 1/sqrt(3x+2y) put x = 4, y =9 = 1/sqrt(30)
