-x-3y=-1 -x-3y=2 what do the two equations represent

Mathematics
1 answer:
murzikaleks [220]3 years ago
8 0

Answer:

Step-by-step explanation:

-x - 3y = -1

-3y = x - 1

y = -1/3x + 1/3.....slope here is -1/3 and y int is 1/3

-x - 3y = 2

-3y = x + 2

y = -1/3x - 2/3...slope here is -1/3 and y int is -2/3

these two equations represent parallel lines. Equations that have the same slope and different y intercepts mean the lines are parallel and never cross each others path.

If pr = 4x – 2 and rs = 3x – 5, which expression represents ps?
slamgirl [31]
This is from simple math knowledge of lines, segments and points. From the given data, pr and rs are line segments in the line ps. Thus, we add segments pr and rs together to solve for the line ps. 

pr + rs = ps
4x - 2 + 3x - 5 
(Add like terms) = 7x -7
(Further simplify) = 7(x-1)

Therefore, the final answer or expression of ps = 7(x-1).

Gemiola [76]

Answer:

The y-intercept refers to the y-coordinate of a point where a curve or a line, intersects the y-axis.

In the given equation, the y-intercept is ( 0, 9.5).

Step-by-step explanation:

We have been given the equation;

y=0.10x+9.50

The y-intercept is simply the y-coordinate of a point where the line intersects the y-axis. At this point, the value of x is usually zero.

y = 0.10 (0) + 9.50

y = 0 + 9.50

y = 9.50

is our y-intercept

A frozen dinner is divided into 3 sections on a circular plate with a 12-inch diameter. The central angle formed by the peach co
Vsevolod [243]

Answer:

D. 5 inches

Step-by-step explanation:

Given:

A frozen dinner is divided into 3 sections on a circular plate with a 12-inch diameter.

That means complete angle having 360° is divided into 3 section.

The central angle formed by the peach cobbler is 105 degrees.

The central angle formed by the pasta is 203 degrees.

<u>Question asked:</u>

What is the approximate length of the arc of the section containing the peas?

<u>Solution:</u>

The central angle formed by the peas = 360° - 105° - 203°

                                                                = 52°

Ridius,r=\frac{Dameter}{2} =\frac{12}{2} =6\ inches

As we know:

Length\ of\ arc=2\pi r\times\frac{\Theta }{360}

                        =2\times\frac{22}{7} \times6\times\frac{52}{360} \\ \\ =\frac{13728}{2520} \\ \\ =5.44\ inches

Therefore, the approximate length of the arc of the section containing the peas are 5 inches.
