-3 + 6x. Which expression shows the correct factorization?
Here are the ones to pick from
1. -2 + -2 +6 +x
2. 6(-2 +x)
3. 6(-2 +x)
4. -3 (1 - 2x)

Answers

Answer:

Option #4

Step-by-step explanation:

Expand option #4

=-3(1-2x)

=-3 -2x*-3

=-3+6x which is what your original equation was.

becoz it is a multiple choice, we can go by elimination, hence when we expand #4, we will get -3+6x

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?

Answers

To determine whether Keira's statement is correct, we need to analyze the information provided.

According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.

If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.

However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.

Therefore, without additional information, we cannot determine the accuracy of Keira's statement.
in order to know if Keira has two tickets left, we need to know the first number of tickets without that number there is no way to find the remainder

Answer:

B) 28 inches.

Step-by-step explanation:

After 1/8 of a ribbon is thrown away, the remaining part is cut into two pieces whose lengths are in the ratio 4 : 5.

And we want to find the length of the shorter ribbon from the two remaining pieces.

We are given that 9 inches of the original ribbon was thrown away. Since this is 1/8 of the total length, we can write that:

\(\displaystyle \frac{1}{8}L=9\)

Where L represents the total length of the ribbon.

Solve for the total length:

\(\displaystyle L=72\text{ inches}\)

So, the original length of the ribbon was 72 inches.

Since we threw away 9 inches of it, we now only have 63 inches.

This is then cut into two pieces in a ratio of 4 : 5. Let x represent the constant. Thus:

\((4x)+(5x)=63\)

Solve for x:

\(9x=63\Rightarrow x=7\)

Hence, the two remaining ribbons measure 28 inches and 35 inches.

Therefore, our answer is B.

Weather maps 1- WHAT DOES H AND L STAND FOR ON A WEATHER MAP?2- WHAT KIND OF WEATHER DO WE GET WHEN HIGH

Answers

Answer:

answer for 1: on weather maps, these readings are represented as a blue "H" for high pressure or a red "L" for low pressure.

answer for 2: A low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air. In general, areas that experience high atmospheric pressure also experience fairweather. Low pressure systems can cause the formation of clouds and storms.

answer for 3: A high pressure system is a whirling mass of cool, dry air that generally brings fair weatherand light winds. When viewed from above, winds spiral out of a high-pressure center in a clockwise rotation in the Northern Hemisphere. These bring sunny skies. A low pressure system is a whirling mass of warm, moist air that generallybrings stormy weather with strong winds. When viewed from above, winds spiral into a low-pressure center in a counterclockwise rotation in the Northern Hemisphere.

answer for 4: cold front is indicated on the line by blue triangles pointing away from the colder air and in the direction towards which the cold air is moving. A warm front is a front that is moving in the direction of the colder air. In this case, warm air is colliding with the cold air(warm air is "doing" the colliding).

answer for 5: A stationary front forms when a coldfront or warm front stops moving. Thishappens when two masses of air are pushing against each other, but neither is powerful enough to move the other. Winds blowing parallel to the frontinstead of perpendicular can help it stay in place. answer for 6: Many fronts cause weather events such as rain, thunderstorms, gusty winds, and tornadoes. At a cold front, there may be dramatic thunderstorms. At a warm front, there may be low stratus clouds. Usually, the skies clear once the fronthas passed. answer for 7: As the warm air mass rises, it condenses into a broad area of clouds. A warm front brings gentle rain or light snow, followed by warmer, milder weather. Stationaryfront Forms when warm and cold air meet and neither air mass has the forceto move the other

Find the slope of the line that passes through the points (−2/3, 3/4) and (5/6, −1/2).

Answers

Answer:

\(-\frac{5}{6}\)

Step-by-step explanation:

Use the slope formula :\(\frac{y2-y1}{x2-x1}\)

-1/2 is y2, 3/4 is y1, 5/6 is x2, and -2/3 is x1.

\(\frac{-1/2-3/4}{5/6-(-2/3)}\)

\(\frac{-5/4}{5/6+2/3}\)

\(\frac{-5/4}{9/6}\)

\(\frac{-5}{4}\) ÷ \(\frac{9}{6}\)

\(-\frac{5}{4}\) • \(\frac{6}{9}\)

\(-\frac{5}{2}\) • \(\frac{3}{9}\)

\(-\frac{15}{18}\)  

\(-\frac{5}{6}\)

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111

Answers

Here are the pairs matched with their products:

- (-5)(4.2) matches with -21

- (-7)(-3) matches with 21

- (2.5)(-9) matches with -22.5

Pairs (4) and (5) do not have corresponding products in the given options.

The products of the given pairs of numbers are:

(-5)(4.2) = -21

(-7)(-3) = 21

(4)(5) = 20

(2.5)(-9) = -22.5

So, the pairs of numbers and their products are as follows:

(-5)(4.2) = -21 matches with -21.

(-7)(-3) = 21 matches with 21.

(4)(5) = 20 matches with 20.

(2.5)(-9) = -22.5 matches with -22.5.

Answer:

1.      5 ( − 6 ) 2

2.     (−16)(+16)

3.     ( 7q-3r) ^2  

Step-by-step explanation:

5a^2 - 60a + 180   we factor 5 as multiple of a alone (outside of brackets)

Then we keep the common a with its number as 180 doesn't share a

Then we look solely for two numbers that add up to 60 and multiply to 180

We show in the first line what we found and then continue to factor the square of a in format of 5a^(2) and format of -6a-6a to find 5(a2−6a−6a+36) like below until its completed in factored form - 6 -6 would multiply to find +36 and -6-6 subtracts to find -12.

5a^2 - 60a + 180

5(  ^ 2 − 1 2 + 3 6)  

5 ( ^ 2 − 6 − 6 + 3 6 )

5(a^{2}-6a-6a+36)

5(a2−6a−6a+36)

5 ( ( − 6 ) − 6 ( − 6 ) )

5 ( − 6 ) ( − 6 )

(7q )^2 + (7 x 6 + qr) + 3r^2  like by like = 7q and 3r as 3+3 = 6 when squared is our factor outside of brackets and we notice that 6 is not squared in rule.

Answer:

Y= mx + b

so Y = 1/3x + 2

just substitute

Due to the answer requesting slope intercept form, one shall use the points (3,2) in order to substitute for b. Slope intercept form is formatted in y = mx + b, which m would be your slope, which in this particular problem was given; therefore, y = 1/3x +b.


Now, we shall use points (3,2) as the substitutes for the solution for b, which 3 would be the input and 2 would be y.


Therefore, 2 = 1/3(3) + b
2 = 1 + b, therefore, one would be subtracted from 2 which would give us the answer of b equaling to one. Thus, y = 1/3x + 1
