Write the equation of the line shown (3,6) (3,-4)
lozanna [386]

Answer:

The equation of line is given as  x=3

Step-by-step explanation:

Point on the line given :

(3,6),(3,-4)

We can find the slope of the line first from the given points.

Slope(m)=\frac{y_2-y_1}{x_2-x_1} = \frac{-4-6}{3-3}=\frac{-10}{0}== Undefined.

The slope of the line is undefined which means that the line is parallel to y-axis.

From the points known to us we can tell that the line passes through x=3

∴ The equation of line is given as  x=3

Diameter of wheel of car is 35 cm . how much distance will it cover in 1000 revolution.
kirill115 [55]

Answer: 35000π cm.

Step-by-step explanation:

First find circumference

Circumference = 2 × π × radius

Circumference = 2 × π × ( diameter / 2 )

Circumference = 2 × π × ( 35 / 2 )

Circumference = 35 × π cm

Now,

1 revolution = 1 circumference

1000 revolution = 1000 circumference

1000 revolution = 1000 × (35 × π)

1000 revolution = 35000π cm.

Simplify the difference. (4w^2 – 4w – 8) – (2w^2 + 3w – 6)
Blababa [14]

Answer:

  2w^2 -7w-2

Step-by-step explanation:

(4w^2 – 4w – 8) – (2w^2 + 3w – 6)

Distribute the minus sign

(4w^2 – 4w – 8) – 2w^2 - 3w + 6

I like to line them up vertically

  4w^2 – 4w – 8

– 2w^2 - 3w + 6

-----------------------------

  2w^2 -7w-2
