Write the equation of the line parallel to 3x-y=7 that passes through point (-5, -3)
IceJOKER [234]
<h2>Answer:</h2>

\boxed{y=3x+12}

<h2>Step-by-step explanation:</h2>

In this problem we know the equation of a line, which is:

3x-y=7

We also can write this equation as:

y=3x-7

This line has a slope m=3 which is also the slope of the line we are looking for because they're parallel. We also have a point (-5,-3). Therefore, we can write this equation as follows:

y-y_{0}=m(x-x_{0}) \\ \\ y-(-3)=3(x-(-5)) \\ \\ y+3=3(x+5) \\ \\ y+3=3x+15 \\ \\ \boxed{y=3x+12}

From the figures below, the line in red is 3x-y=7 while the line in blue is y=3x+12 and this line passes through the point (-5, -3)!

What is a linear equation ?
dusya [7]

A linear equation is an equation that represents a line. A linear equation has a variable raised to the 1st power.

For example, Y = 2x, Y = x + 1, Y = 8x - 3 are examples of linear equations.

However, something like Y =\frac{4}{x} and Y = 6^{x} seem to have a variable raised to the 1st power, but they're not linear.

A sports ball has a diameter of 15 cm. Find the volume of the ball and select the correct units. Round your answer to 2 decimal
Setler79 [48]

The volume of the ball has a diameter of 15 centimeters around 2 decimal places is 1767.15 cubic centimeters.

<h3>What is Geometry?</h3>

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

A sports ball has a diameter of 15 cm.

Then the radius of the ball will be

r = d/2

r = 15/2

r = 7.5 cm

Then the volume of the ball will be

\rm Volume = \dfrac{4}{3} \times \pi \times r^3\\\\Volume = \dfrac{4}{3} \times \pi \times 7.5^3\\\\Volume = \dfrac{4}{3} \times \pi \times 421.875\\\\Volume = 1767.15\ cm^3
