Answer:

You would graph a vertical line at (-49, 0)

Step-by-step explanation:

3x = -135

Divide both sides by 3

x = -45

You would graph a vertical line at (-49, 0)

P.S., that system acts strange sometimes so be sure to only do one square up once you press -45. :)

Answer:

see below

Step-by-step explanation:

first isolate x

3x = -135

divide both sides by 3

3x/3 = x

-135/3 = -45

x = -45

we can then graph it

x is gonna be equal to -45

so draw a point on the x intercept at -45 and draw a vertical line going up and down

it should look like the graph shown below

WHAT IS THE FORMULA FOR 1,OOO DOLLARS WITH 5% INTEREST COMPOUNDED FOR 8 YEARS

stellarik [79]

Answer:

Is it compounded monthly, weekly, yearly, or continuously?

Step-by-step explanation:

then the formula would be P=A/(1+r/n)^tn where r is interest rate as a decimal, A is the initial value, t is the time and n is the number of times compounded in a unit 't'. Plugging in the values, we would get 1000/(1+.05/1)^8(1)=$1477.46

What was the median number of posts made?

mariarad [96]

Using it's concept, it is found that the median number of posts made was of 8.5.

<h3>What is the median of a data-set?</h3>

The median of the data-set separates the bottom half from the upper half, that is, it is the 50th percentile.

In this problem, the total number of observations is the sum of the frequencies, hence:

T = 1 + 0 + 3 + 1 + 2 + 1 + 1 + 2 + 3 + 5 + 9 = 28

Even number, hence the median is the mean between the 14th and the 15th elements, of the ordered set, hence:

M = (8 + 9)/2 = 8.5.

To remind, the ordered set is: {0, 1, 1, 1, ..., 8, 8, 8, 9, 9, 9, 9, 9, 10, 10, 10, 10, 10, 10, 10, 10, 10}

The median number of posts made was of 8.5.

Suppose that the division N/5 leaves a remainder of 4, and the division N/2 leaves a remainder of 1, what is the ones digit on N

Tju [1.3M]

Since N/2 leaves a remainder, N must be odd and ends with 1, 3, 5, 7, or 9.

N/5 also leaves a remainder, so N is not divisible by 5, so it does not end in 5.

The only correct choice is then 9, since

1 = 0•5 + 1 and 1 = 0•2 + 1

3 = 0•5 + 3 and 3 = 1•2 + 1

7 = 1•5 + 2 and 7 = 3•2 + 1

9 = 1•5 + 4 and 9 = 4•2 + 1

Alternatively, the given information is equivalent to saying

$N\equiv 4\pmod5\\\\N\equiv1\pmod2$

Then you can use the Chinese remainder theorem to find N.
