Answer:
The difference of the polynomials (5x3 + 4x2) – (6x2 – 2x – 9) is 5x3 – 2x2 + 2x + 9.
Step-by-step explanation:
Answer:
5x3−2x2+2x+9
Step-by-step explanation:
Distribute the Negative Sign:
=5x3+4x2+−1(6x2−2x−9)
=5x3+4x2+−1(6x2)+−1(−2x)+(−1)(−9)
=5x3+4x2+−6x2+2x+9
Combine Like Terms:
=5x3+4x2+−6x2+2x+9
=(5x3)+(4x2+−6x2)+(2x)+(9)
=5x3+−2x2+2x+9

hector's bag contains three kinds of marbles. he is 2 times more likely to randomly select a white marble than a striped marble. he is equally likely to select a white marble as a dotted marble. of the original bag of 10 marbles is tripled, keeping the ratios of striped, dotted, and white marbles the same, how many of each type of marble are in the bag?
Answer: 12 white, 12 dotted and 6 striped
Step-by-step explanation:
There are 10 marbles. There are twice as many white marbles than striped marbles, and there are the same amount of white marbles and dotted marbles.
Trial and error concludes that there are 4 white marbles, 4 dotted marbles and 2 striped. Then, you have to triple them (multiply by 3)
4x3=12
4x3=12
2x3=6
12 white, 12 dotted and 6 striped

Use the Distributive Property to simply each expression.
6(11+x)
Answer:
66 + 6x
Step-by-step explanation:
Because the 6 is outside the parenthesis, that means you need to multiply everything in the parenthesis by 6.
6 x 11 is 66 and 6 x X is 6x. So the simplified expression would be 66 + 6x.

When Connor was 16, he bought his first car. It had 1.67 x 10^5 miles on it. Connor is now 55 and wants to buy his dream car. He wants a
new car or a used one with low miles. The car he ends up buying has 4.35 x 10^3 miles.
How many times greater were the miles on his old car than his new car? Round to the nearest whole number.
explanation too please!
Answer:
4350
Step-by-step explanation:
First,we do 10^3
10 x 10 x 10
100 x 10
1000
Then we bring down
4.35 and we multiply it by 1000
And Last, we get
4350 as the answer
The miles on Connor's old car were 39 times greater than the miles on his new car.
What is the distance?A mathematical number known as distance measures "how much ground an object has traveled" while moving. Distance is defined as the product of speed and time.
To solve this problem, we need to divide the number of miles on Connor's old car by the number of miles on his new car and round the result to the nearest whole number.
The number of miles on Connor's old car is 1.67 x 10⁵ miles and the number of miles on his new car is 4.35 x 10³ miles, so the number of times greater the miles on his old car are than his new car is:
(1.67 x 10⁵ miles) / (4.35 x 10³ miles) = 38.6
Rounded to the nearest whole number, this is 39.
Therefore, the miles on Connor's old car were 39 times greater than the miles on his new car.

A figure is graphed on a coordinate grid as shown.
The figure is rotated 180° clockwise with the origin as the center of rotation to create a new figure. Which rule describes this transformation?
(x, y) → (−x, −y)
(x, y) → (x, −y)
(x, y) → (−y , −x)
(x, y) → (−x, y)
Answer:
It’s the first one trust me
Step-by-step explanation:
The rule for the transformation of the figure is rotated 180° clockwise with the origin as the center of rotation to create a new figure is,
⇒ (x, y) → (- x, - y)
What is Translation?A transformation that occurs when a figure is moved from one location to another location without changing its size or shape is called translation.
Given that;
The figure is rotated 180° clockwise with the origin as the center of rotation to create a new figure.
Now,
We know that;
The rule for the transformation of the figure is rotated 180° clockwise with the origin as the center of rotation is,
⇒ (x, y) → (- x, - y)
Therefore, The rule for the transformation of the figure is rotated 180° clockwise with the origin as the center of rotation to create a new figure is,

A time line is a useful way to represent important dates and events throughout history. It's common to divide a historical time line into events that occurred either BC (to the left of zero) or AD (to the right of zero). The year you're living in right now takes place in AD. BC AD 0 When performing mathematical operations involving dates, we can think of a historical time line as a number line. On the number line, the years increase from left to right. If zero represents the origin, the years to the right of zero are considered positive numbers and the years to the left of zero are considered negative numbers. Using this analogy, here are some events that might appear on a historical number line:
Event Historical Time Line Number Line
(The first ancient games take place in Olympia, Greece. 776 BC -776)
(Construction begins on the Great Wall of China. 221 )
(BC -221 World War I begins in central Europe. AD 1914 1,914 (or 1914)
Use these ideas about time lines and number lines to answer the questions that follow.
