Step-by-step explanation:

as -1×-1=+1 (positive 1)

which is different from the answer in step 1 because you needs to get -1 for the correct answer.

-1(x-1)= -x+1  

the real answer is -1(x+1)= -x-1    

Julian factored -1 incorrectly in the second step. The correct option is B.

What is a polynomial?

A polynomial in mathematics is an expression made up of coefficients and indeterminates and involves only the operations of multiplication, addition, subtraction, and non-negative integer exponentiation of variables.

Given polynomial 2x⁴ + 2x³ - x² - x will be solved as below:-

P = 2x⁴ + 2x³ - x² - x

P = x ( 2x³ + 2x - x - 1 )

P = x ( 2x² [ x + 1 ] -1 ( x + 1 )

P = x ( 2x² - 1 ) ( x + 1 )

Therefore, Julian factored -1 incorrectly in the second step. The correct option is B.

a conference hall has 33 rows.the last row contains 80 seats each row has two fewer seats than the row behind it.how many seats are there second to the last row?​

Answers

Answer:

there are 84 seats in the  second to the last row

Step-by-step explanation:

Given that

each row has two fewer seats than the row behind it

It means that

if first row has x seats then

no of seat in second row has (x-2) seats.

and similarly

no of seat in third  row =no of seat in second row - 2seats.

no of seat in third  row = (x-2) seat - 2 seats = x - 4 seats

_____________________________________________

Given that

last row has 80 seats

let the number of seat in first to the last row be x

then number of seat in last row = x-2

we know number of seat in last row = 80

thus

x - 2 = 80

x = 82

Thus,

the number of seat in first to the last row is 82

Similarly let the number of seat in second to the last row be y

then number of seat in first to the  last row = y-2

since number of seat in first to the last row is 82

thus

y-2 = 82

y = 82 + 2 = 84

Thus, there are 84 seats in the  second to the last row.

How would you find the quadratic that goes through the point (4,0), the axis of symmetry is x=7, and it also goes through the point (1,5)?

Answers

9514 1404 393

Answer:

  y = (5/27)(x -7)^2 -5/3

Step-by-step explanation:

Use the given points to find the unknowns in the equation.

If the axis of symmetry is x=7, then the equation can be written in the form ...

  y = a(x -7)^2 +b

Filling in the two point values, we have two equations:

  0 = a(4 -7)^2 +b   ⇒   9a +b = 0

  5 = a(1 -7)^2 +b   ⇒   36a +b = 5

__

Subtracting the first equation from the second, we have ...

  (36a +b) -(9a +b) = (5) -(0)

  27a = 5

  a = 5/27

Substituting that value into the first equation gives ...

  9(5/27) +b = 0

  5/3 +b = 0

  b = -5/3

So, the quadratic can be written in vertex form as ...

  y = (5/27)(x -7)^2 -5/3

What is the slope(m) and the y-intercept (b)

Answers

Answer:

x=6.0

Step-by-step explanation:

the slope (m) is -4, indicating a downward slope, and the y-intercept (b) is -12,

In the equation y = -4x - 12, the coefficient of x, -4, represents the slope of the line. The slope (m) is the ratio of the vertical change to the horizontal change between any two points on the line. In this case, the slope is -4, indicating that for every unit increase in x, the y-value decreases by 4.

The constant term, -12, represents the y-intercept (b). The y-intercept is the point where the line intersects the y-axis. In this equation, the y-intercept is -12, which means that the line crosses the y-axis at the point (0, -12).

To summarize, the slope (m) is -4, indicating a downward slope, and the y-intercept (b) is -12, representing the point where the line crosses the y-axis.

The double number line shows that 4 pounds of tomatoes cost $14. Draw tick marks and write labels to show the prices of 1, 2, and 3 pounds of tomatoes.

Answers

Answer:

every tick is 3.50

Step-by-step explanation:

14/4=3.5

The price of one, two, and three pounds of tomatoes is $10.5. Each quantity is represented by its own number line in a double number line, with corresponding pairs of values lined up.

How are double number lines created?Equal ratios are represented by two parallel number lines in a double number line diagram. The tick marks are in the same places on both number lines.Despite the fact that the other numbers change frequently, the tick marks labeled with 0 always line up.Diagrams with a double number line can show you how two quantities are related in terms of their ratios.They work best when the quantities have different units. (The unit rate is represented by the number 1) Students can more easily "see" that the same ratio can take many different comparable shapes when using double number line diagrams.

Therefore,

Given,

4 pounds of tomatoes cost  = $14

We find  the prices of 1, 2, and 3 pounds of tomatoes

14/4 = 3.5

So,

1 lb = 3.5

2 lbs = 2× 3.5 = 7

3 lbs= 3 × 3.5 = 10.5

Hence, The price of one, two, and three pounds of tomatoes is $10.5.
