B)

14a2b + 42ab2 + 56abc

C)

–14a2b – 42ab2 + 56abc

D)

–14a2b – 42a2b2 + 56c

Answers

Answer 1

Answer:

-14 a^2 b - 42 a b^2 + 56 a b c    C. is the answer

Step-by-step explanation:

Expand the following:

-14 a b (a + 3 b - 4 c)

Hint: | Distribute -14 a b over a + 3 b - 4 c.

-14 a b (a + 3 b - 4 c) = -14 a b a - 14 a b×3 b - 14 a b (-4 c):

-14 a b a - 14×3 a b b - 14 (-4) a b c

Hint: | Combine products of like terms.

-14 a b a = -14 a^2 b:

-14 a^2 b - 14×3 a b b - 14 (-4) a b c

Hint: | Combine products of like terms.

-14 a b×3 b = -14 a b^2×3:

-14 a^2 b + -14×3 a b^2 - 14 (-4) a b c

Hint: | Multiply -14 and 3 together.

-14×3 = -42:

-14 a^2 b + -42 a b^2 - 14 (-4) a b c

Hint: | Multiply -14 and -4 together.

-14 (-4) = 56:

Answer: -14 a^2 b - 42 a b^2 + 56 a b c

Find two numbers such that five times the larger plus three times the smaller is 47, and four times the larger minus twice the smaller is 20.​

Answers

Let x and y be the larger and smaller numbers respectively.
Use the given fact "five times the larger plus three times the smaller is 47" to set up an equation:
5x + 3y = 47 ...................(1)
Use the given fact "four times the larger minus twice the smaller is 20" to set up another equation:
4x - 2y = 20 ...................(2)
Multiply both sides of (1) by 2, we have:
10x + 6y = 94 ............................(3)
Multiply both sides of (2) by 3, we have:
12x - 6y = 60 ............................(4)
Add (3) and (4), we have
22x = 154
x = 7
Substituting x = 7 into (1), we have
5*7 + 3y = 47
Solving for y, we have:
35 + 3y = 47
3y = 12
y = 4

In the last quarter of a high school football game, your team i s behind by 21 points. A field goal is worth 3 points and a touchdown (after the extra point is worth 7 points. Let x represent the number of field goals scored and y represent the number of touchdowns scored. Write an inequality that models the different number of field goals and touchdowns your team could score to win the game. (Assume the other team doesn't score any more points.)​

Answers

Answer:

3x + 7y > 21

Step-by-step explanation:

3x + 7y > 21

where:

x = number of field goals needed to win

y = number of touchdowns (plus extra point) needed to win

Since your team is 21 points behind and you want to win the game, not tie it, the number of field goals and touchdowns must result in a number higher than 21, not equal to or higher than.

Answer:

3x + 7y > 21

3x + 7y > 21

where:

x = number of field goals needed to win

y = number of touchdowns (plus extra point) needed to win

An independent study commissioned by the stadium showed that running a cable TV ad 5 times daily for a week generated 1,200 ticket sales. The stadium wants to sell out an upcoming show, which requires the sale of 13,200 tickets. How long should the stadium run the cable ad in order to reach this target?

Answers

Answer

I think 55 times

Step-by-step explanation:

13,200/1,200 = 11

5/1200 =  x/13,200

so if 1,200*11=13, 200 then 5*11= 55.

btw , could u give me the brainliest if i am right?

The total time the stadium runs the cable ad in order to reach this target is 11 days and this can be determined by using the unitary method.

Given :

Running a cable TV ad 5 times daily for a week generated 1,200 ticket sales. The stadium wants to sell out an upcoming show, which requires the sale of 13,200 tickets.

The following steps can be used in order to determine the total times the stadium run the cable ad in order to reach this target:

Step 1 - The unitary method can be used in order to determine the total times the stadium runs the cable ad in order to reach this target.

Step 2 - According to the given data, running a cable TV ad 5 times daily for a week generated 1,200 ticket sales.

Step 3 - If running TV ad 5 times daily sales 1200 tickets then to sell 13200 tickets the total times the ad is running is:

[tex]=\dfrac{13200}{1200}\times 5[/tex]

= 55 times

Step 4 - Now, if 5 times ad running in one day then 55 times ad running in:

[tex]=\dfrac{55}{5}\times 1[/tex]

= 11 days

How to graph the following function on the axes provided?

Function is a type of relation, or rule, that maps one input to specific single output.

The piecewise function is given as:

f(x) =  - 6  for  -6< x < 1

       -2x + 5 for  1< x < 6

The above means that we plot the function on their interval or domain.

i.e. we plot f(x) = - 6  on the interval x < 0 and f(x) = -2x + 5 on the interval x < -6

Next, we plot the graph of the piecewise function.

Thus, The graph of the piecewise function is attached below.

Find the equation of a straight line passing through the point (0,1) which is perpendicular to the line y=-2x+2

Answers

Answer:

y = [tex]\frac{1}{2}[/tex] x + 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 2x + 2 ← is in slope- intercept form

with slope m = - 2

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-2}[/tex] = [tex]\frac{1}{2}[/tex]

The line crosses the y- axis at (0, 1) ⇒ c = 1 , then

y = [tex]\frac{1}{2}[/tex] x + 1 ← equation of perpendicular line
