I WILL MARK BRAINS!!! 10 POINTS

1 answer:

5 0

A line with undefined slope is a vertical line parallel to the y-axis, passing through all points with the same x-coordinate.

For this reason it's equation is x = c

where c is the value of the x-coordinate the line passes through

For (- 3, 5 ) the x-coordinate is - 3, hence

x = - 3 → is the equation of the line

Which expression shows the area of the base of each pyramid? (One-fourth x) squared in.2 (One-third x) squared in.2 (One-half x)

777dan777 [17]

Answer:

(a) $Area = (\frac{x}{4})^2$

Step-by-step explanation:

The question is incomplete. (See comment for complete question).

From the completed question, we have:

$Total\ base\ length = x$

$n = 8$ --- number of pyramids

Required

An expression for the area of the base

The total base length of the pyramid represents the perimeter of the base.

And since the base is a square, then the following relationship exist.

$Total\ base\ length = 4L$

Where L represents the length of each side.

This gives

$4L = x$

Make L the subject

$L = \frac{x}{4}$

The area of the base is then calculated as:

$Area = L^2$

$Area = (\frac{x}{4})^2$

The first painter can finish a paint job in 2 hours. The second painter can finish the same job in 8 hours. How long would it ta

vampirchik [111]

Answer: $1\frac{3}{5}$ hrs

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

1st painter: $\frac{1}{2}$

2nd painter: $\frac{1}{8}$

1st + 2nd = Together

$\frac{1}{2}$ + $\frac{1}{8}$ = $\frac{1}{x}$

$\frac{1}{2}(8x)$ + $\frac{1}{8}(8x)$ = $\frac{1}{x}(8x)$

4x + x = 8

5x = 8

x = $\frac{8}{5}$

= $1\frac{3}{5}$

meriva

Okay, all we need to do is divide 8 from both sides:

-104/8=-13

So x=-13
