1. What is the solution to the system below? x+y=5 1x- y=3

Mathematics
1 answer:
Alika [10]3 years ago
5 0

Answer:

(4,1)

Step-by-step explanation:

x+y=5

x- y=3

Add the equations together to eliminate y

x+y=5

x- y=3

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

2x = 8

Divide each side by 2

2x/2 = 8/2

x = 4

Now we can find y

x+y = 5

4+y = 5

Subtract 4 from each side

4+y-4 = 5-4

y =1

Give the equation of the horizontal asymptote shown below.
Oxana [17]
Polynomial division yields

\dfrac{7x^2}{x^2+5}=7-\dfrac{35}{x^2+5}

As x\to\pm\infty, you have the remainder term approaching 0, so the horizontal asymptote is the line y=7.

Korvikt [17]
Equation: 450 = 128 + 150 + n

work:

128+150 = 278

2nd step:
450-278 = 172

answer: 172

3rd step (checking) :
450 = 128 + 150 + 172
450 = 278 + 172
450 = 450

Help with #1 so I can get the gist of it please?
Virty [35]

Answer:

so you graph at (0,2), and go up one, over two for every other point you graph.

Step-by-step explanation:

rise over run.

basically, the m is the slope, and b is the y intercept (where it intersects the y axis).

so when looking at how to graph the line based on 1/2 or any other number, I use rise/run, which is basically telling us tha we need to go up one and over 2 (1/2)

if that makes any sense, let me know if you have any further questions. you got this, youre doing your best!!

slope is the start of your endless pain.

If the relative frequency of getting a red on a spinner is 0.4 how many reds would you expect to get in 300spins?
Sauron [17]

This relative frequency is an experimental probability:  that of getting a red on a spinner.  In 300 spins, we'd expect to get 0.4(300), or 120, reds.
