Write in point-slope form the equation of the line that is parallel to the given line and passes through the given point.Your fi
SOVA2 [1]

Answer:

y = x

Step-by-step explanation:

The given equation is

y = x + 5

The slope of this line

m = 1

Since all parallel lines have the same slope, the slope of our line is also m=1.

We now use the point-slope formula

y-y_1=m(x-x_1)

Since the line passes through (-1,-1)

We gave

x_1=-1,y_1=-1

We substitute the slope and point to get

y -  - 1 = 1(x -  - 1)

y + 1 = x + 1

y = x

A ball has a volume of 4 cubic inches (in3). Use the fact that 1 inch is equal to 2.54 cm to convert this volume to cubic centim
Marina86 [1]

Answer:

V = 65.548 cm³

Step-by-step explanation:

We have,

Volume of a ball is 4 cubic inches or 4\ \text{inch}^3.

We know that, 1 inch = 2.54 cm

It is required to convert this volume to cubic centimetre or \text{cm}^3.

4\ \text{inch}^3=4\ \text{inch}^3\times (\dfrac{2.54\ \text{cm}}{1\ \text{inch}})^3\\\\V=65.548\ \text{cm}^3

So, the volume of the ball is 65.548 cm³.

1 - The value of p in the equation is p = 0.

2 - The simplified form of the equation is 3x = 1, the reason behind this is when you do the equation, you get x = 1/3. When you do the equation 3x = 1 you get x = 1/3 as well.

3 - The value of z in the equation is z = 13.

4 - In order to figure out what step he did something wrong on, we first need to solve the problem, the answer we will get is x = 2.
To do this the easy way, we can solve each step, and see what one wouldn't equal 2, which the step he did wrong is Step 2.
So, to do Step 2 correctly, it would be: Step 2 - 12x − 6 = 14 + 2x.
