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

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! ^ ^

The graph shows the number of gallons of white paint that were mixed with gallons of blue paint in various different ratios:

(look below)

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.

In slope-intercept form, write the equation of the line that passes through points (0, -9) and (-1, -5).

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

y = -4x - 9

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.

He had collected a quantity of rice by begging, and after having dined off it, he filled a pot with what was left over. He hung the pot on a peg on the wall, placed his couch beneath, and looking intently at it all the night, he thought, "Ah, that pot is indeed brimful of rice. Now, if there should be a famine, I should certainly make a hundred rupees by it. With this I shall buy a couple of goats. They will have young ones every six months, and thus I shall have a whole herd of goats. Then, with the goats, I shall buy cows. As soon as they have calved, I shall sell the calves. Then, with the calves, I shall buy buffaloes; with the buffaloes, mares. When the mares have foaled, I shall have plenty of horses; and when I sell them, plenty of gold. With that gold I shall get a house with four wings. And then a Brahman will come to my house, and will give me his beautiful daughter, with a large dowry. She will have a son. When he is old enough to be danced on his father's knee, I shall sit with a book at the back of the stable, and while I am reading, the boy will see me, jump from his mother's lap, and run towards me to be danced on my knee. He will come too near the horse's hoof, and, full of anger, I shall call to my wife, 'Take the baby; take him!' But she, distracted by some domestic work, does not hear me.
