Answer:

y=2x+2

Step-by-step explanation:

The y-intercept, or b, is 2 because the line intersects on the y-axis at (0,2)

To figure out slope, or m, it is the change in y over the change in x or rise over run.

You subtract the y-coordinates

-6-6 = -12

Then you subtract the x-coordinates

-4-2 = -6

You divide the two (the change in y over the change in x)

-12/-6 = 2

Your slope, or m, is 2 or 2/1

You then plug the slope and y-intercept into slope-intercept form (y=mx+b) to receive

y=2x+2 or y=(2/1)x+2

2(x-3)=3/4(8x-12)<br> step by step please
Umnica [9.8K]

Answer:

x = \frac{3}{4}

Step-by-step explanation:

2(x-3)=\frac{3}{4} (8x-12)

2x-6 = \frac{3}{4}8x- \frac{3}{4} 12

2x-6 = 6x - 9

-6+9 = 6x - 2x

3 = 4x

x = \frac{3}{4}

The cost of painting the total outside surface of a closed cylindrical tank at 60 paise per meter squae is Rs237.60. The height
valkas [14]

Answer:

volume=509.25 dm^{3}

Step-by-step explanation:

Curved surface area=\frac {237.6}{0.6}=396 dm^{2}=2\pi R(R+H) where R is radius and H is height

Since H=6R then curved surface area=2\pi R(R+6R)=14\pi R^{2}

Therefore,  

396 dm^{2}=14\pi R^{2} and making R the subject

R=\sqrt {\frac {396}{14\pi}}=\sqrt {(9.003622)}= 3.000604 m

Therefore, H=6R=6*3.000604=18.00362 m

Volume=\pi R^{2}H=\pi*3.000604^{2}*18.00362=509.2453 dm^{3}

Therefore, volume=509.25 dm^{3}
