for each equation, find the ordered pair whose x-coordinate is -4.

1. y=18-5x 2. 2x + 3y=4 3. -7 + 6y=10

Answers

Final answer:

To find the ordered pairs with an x-coordinate of -4 for the given equations, substitute -4 for x in the first two equations and solve for y. The resulting ordered pairs are (-4, 38) and (-4, 4). The third equation does not contain x, so no ordered pair can be found for it.

Explanation:

To find the ordered pair whose x-coordinate is -4 for each given equation, we will substitute x with -4 and solve for y.

Equation 1: y = 18 - 5x

Substitute x with -4:

y = 18 - 5(-4) = 18 + 20 = 38

The ordered pair is (-4, 38).

Equation 2: 2x + 3y = 4

Substitute x with -4:

2(-4) + 3y = 4

-8 + 3y = 4

3y = 4 + 8

3y = 12

y = 12 / 3

y = 4

The ordered pair is (-4, 4).

Equation 3: -7 + 6y = 10

This equation does not contain x, therefore we cannot find an ordered pair with x-coordinate -4.

Final answer:

The ordered pairs with an x-coordinate of -4 for each equation are: (-4, 38) for y=18-5x, (-4, 4) for 2x+3y=4, and there is no ordered pair possible for -7+6y=10, as the equation does not contain an x-variable.

Explanation:

To find the ordered pair whose x-coordinate is -4 for each given equation, we substitute x with -4 and solve for y:

For y = 18 - 5x, when x = -4:
y = 18 - 5(-4)
y = 18 + 20
y = 38
The ordered pair is (-4, 38).

For 2x + 3y = 4, when x = -4:
2(-4) + 3y = 4
-8 + 3y = 4
3y = 4 + 8
3y = 12
y = 12 / 3
y = 4
The ordered pair is (-4, 4).

For -7 + 6y = 10, we do not need to substitute x here because it is not present in the equation and no x-coordinate is needed to solve for y. This equation can be solved directly for y by isolating it:
-7 + 6y = 10
6y = 10 + 7
6y = 17
y = 17 / 6
y ≈ 2.83
The value of y is approximately 2.83, but since no x-coordinate is provided we cannot create an ordered pair.

Two factors are multiplied and their product it 34.44. One factor is a whole number. What is the least number of decimal places in the other factor. Explain.

Answers

The answer is 2, because if a number is a whole number, for example 2, you must multiply it by a number with 2 decimals, in this case 17.77, to get 34.44 based on this example.

*There are some cases where this doesn't apply, I think, but it does apply for your question.

The number of decimal places is the count of numbers after the decimal point in a decimal number. The least number of decimal places of the decimal factor is 2.

Let the factors be x and y; where:

[tex]x \to[/tex] whole number

[tex]y \to[/tex] number with decimal

The possible products that give 34.44 are represented as:

[tex]x \times y = 34.44[/tex]

So, we have:

[tex]2 \times 17.22 = 34.44[/tex]

[tex]3 \times 11.48 = 34.44[/tex]

[tex]4 \times 8.61 = 34.44[/tex]

[tex]5 \times 6.888 = 34.44[/tex]

[tex]6 \times 5.74 = 34.44[/tex]

And so on....

From the above computation, we have the decimal places of factors that represent y to be:

2 decimal places; i.e. numbers like 17.22, 11.483 decimal places; i.e. numbers like 6.888

By comparing the decimal places of these two factors, we can conclude that the least number of decimal places is 2.

47/21 can be written as decimal rounded to the nearest tenth as 2.2.

What is Decimals numbers?

Decimal numbers are numbers which has basically a whole number part and a fractional or decimal part after a point called decimal point.

Decimal number system describes the base 10 number system.

The given number is 47/21

This is in the fractional form.

We have to make it in the decimal form.

The actual quotient got when we divide 47 by 21 is,

47/21 = 2.238095

But we need it in the rounded form which is rounded to the nearest tenth.

The tenth place value digit is 2.

The next digit is 3 which is less than 5.

So rounded to the nearest tenth is 2.2.

Hence 47/21 can be written as decimal rounded to the nearest tenth as 2.2.

Answers

friend = -12°C
you = -54°C

difference = 54 - 12

12 degrees below zero tells you we have a negative number, -12. The word "Difference" means we are subtracting. So your equation will be 54 - (-12). Two minuses/negatives back-to-back turn into a plus so the equation is now 54 + 12 = 66.

A single cell can either die, with probability .1, or split into two cells, with probability .9, producing a new generation of cells. Each cell in the new generation dies or splits into two cells independently with the same probabilities as the initial cell. Find the probability distribution for the number of cells in the next generation.

Answers

Final answer:

The probability distribution for the number of cells in the next generation is that there is a 0.1 probability of having zero cells if the original cell dies and a 0.9 probability of having two cells if the original cell splits and both daughter cells survive.

Explanation:

To find the probability distribution for the number of cells in the next generation, we analyze the outcomes of a single cell which can either die with a probability of 0.1 or split into two cells with a probability of 0.9. Since each cell behaves independently, we use the product rule of probability for each scenario.

There are two possible outcomes for a single cell:

The cell dies (probability 0.1)The cell splits into two cells (probability 0.9).

If the initial single cell splits, the next generation will consist of two cells. These two cells will then independently either die or split with the same probabilities as mentioned above. The probability distribution for the number of cells in the next generation is therefore:

Zero cells: This only happens if the initial cell dies, which has a probability of 0.1.One cell: This cannot happen because a cell either dies or splits into exactly two cells.Two cells: This occurs if the initial cell splits and neither of the two new cells dies, which has a probability of 0.9 (since we assume that the probability of both of the daughter cells surviving and splitting is included in the 0.9 probability).

Here, the sum of these probabilities adds to 1, meaning no other outcomes are possible within the scope of this single-generation model.

A square pond is to be built in a park. The pond is 50 meters long and 50 meters wide. There should be a tile sidewalk 5 meters wide all around the pond. The tile is sold in crates of 45 square meters of tile. What will the tile cost if the cost of each box of tile is $74?

Answers

area of the pond is 50*50 = 2500 square meters

the walkway is 5 meters wide so the outside dimensions would be 60 meters by 60 meters

area of walkway is 3600 - 2500 = 1100 square feet

Suppose the pattern 8, 16, 24, 32, ... is continued forever. Will the number 174 appear in the pattern? Why or why not?

Answers

no, because 32 * 2 = 64 and 64 * 2 = 128.
8 * 5 = 40
40 + 128 = 168
168 + 8 = 176

174 will not appear in the pattern 8, 16, 24, 32,

The given pattern 8, 16, 24, 32, ... is an arithmetic sequence where the first term (a) is 8 and the common difference (d) is 8.

We can use the formula for the nth term of an arithmetic sequence, which is:

an = a + (n-1)d

To find out if 174 is in the sequence, we set an to 174 and solve for n:

174 = 8 + (n-1)8

174 = 8 + 8n - 8
174 = 8n
n = 174 / 8
n = 21.75

Since n must be an integer for 174 to appear in the sequence, and 21.75 is not an integer, 174 will not appear in the pattern.
