Answers

Answer:

Solution

First identify the input values. The input value is the first coordinate in an ordered pair. There are no restrictions, as the ordered pairs are simply listed. The domain is the set of the first coordinates of the ordered pairs.

D={2,3,4,5,6}

Next identify the output values. The output value is the second coordinate in an ordered pair. The range is the set of the second coordinates of the ordered pairs. Do not list the same output twice.

The second coordinate in an ordered pair is the output value. The range is the collection of the ordered pairs' second coordinates. Never list the same output more than once.

What is a domain?

The domain of the function is defined as the set of all the possible values of the function. A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values.

Determine the input values first. The first coordinate in an ordered pair makes up the input value. Since the ordered pairs are just listed, there are no restrictions. The set of the ordered pairs' initial coordinates is known as the domain.

D={2,3,4,5,6}

Next, identify the output values. The output value is the second coordinate in an ordered pair. The range is the set of the second coordinates of the ordered pairs. Do not list the same output twice.

Which two expressions are equivalent?
A.
(d + 9) • 3 and d + (9 • 3)
B.
(d − 8) • 2 and (8 − d) • 2
C.
3(4d − 2) and 7d − 5
D.
5(3d + 6) and 15d + 30

Answers

Step-by-step explanation:

We are doing to replace d with 14

(14 + 9 equals 23) times 3 (equals 69) and 14 plus (9 times 3 equals 27) equals 41

(14 -8 equals 6) times 2 equals 12 and 8 -14 equals 6  (times 2) equals -12

3(4 times 14  equals 56-2 equals 54) times 3 equals 162 and 7 times 14 equals 98 -5 equals 93

5(3 times 14 equals 42 plus 6 equals 48) times 5 equals 240 and 15 times d equals 210 plus 30 equals 240

If you multiply this number by any other number, the answer will always be the same. What is this number?

- First right answer will get brainliest! ( Pretty easy once you get it)

Answers

Answer:

1?

Step-by-step explanation:

The number that when multiplied by any other number, the answer will always be the same is 1.

What is multiplication?

Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression some number of times.

Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.

When you multiply any number by 1, the product is always the same as the original number.

For example, 5 times 1 is 5, and 100 times 1 is 100.

So 1 is known as the multiplicative identity because it has the special property that when it is multiplied by any number, the result is always the same as that number.

The number of gallons of white paint mixed with 1 gallon of blue paint is ______.

--I think it could be 4, but it already says 2 gallons of blue paint equals 4 gallons of white paint, so maybe 2...?

Answers

Answer:

2

Step-by-step explanation:

because it is 2 parts white paint one part blue paint

The number of gallons of white paint mixed with 1 gallon of blue paint is 2.

The graph shows the number of gallons of white paint mixed with gallons of blue paint in different ratios.

It is given that 2 gallons of blue paint can be mixed with 4 gallons of white paint.

Since 2 gallons of blue paint can be mixed with 4 gallons of white paint, we can divide both sides by 2 to find the ratio of white paint to blue paint when using 1 gallon of blue paint.

2 gallons of blue paint / 2 = 4 gallons of white paint / 2

1 gallon of blue paint equals 2 gallons of white paint.

So, the number of gallons of white paint mixed with 1 gallon of blue paint is 2.

Use an algebraic approach and show your work in order to earn full credit.

Answers

Answer:

y = -4x - 9

Step-by-step explanation:

First, I plotted the dots (0, -9) and (-1, -5). I then drew a line connecting these two points. Since -9 touches the y-axis that is the y-intercept. Starting at the point (-1, -5), I went down four and one square to the right. This means that my slope is -4, thus the equation y = -4x - 9

Help fast Please!!!!! What is the vertical distance between
(-3, -2.5) and (-3, 5)?

Answers

What I can tell is that they both share the same x coordinate. To help you understand, the horizontal line is from left to right, think of "The sun setting in the horizon.", it is often in the distance as a "left to right" line. So, I hope that helps, this leaves the vertical line as up or down.

With that out of the way, the x-axis lies on the horizontal line, whereas the y-axis lies on the vertical line.

Point coordinates are typically listed as (x, y), so... with that said, to find the distance we'll have to count downwards. As we know, negative x is to the left, negative y is further down, so... -3 to -12 is 9 points away.

Simple method: -3 - 9 = -12, or... -12 - -3 = -12 + 3 = -9.
In other words you get the basic idea, you can also just count, but whatever.

I hope that helps, have a great rest of your day! ^ ^
