Given a polynomial f(x), if (x − 4) is a factor, what else must be true? f(0) = 4 f(0) = −4 f(4) = 0 f(−4) = 0

Answers

Question:

Given a polynomial f(x), if (x − 4) is a factor, what else must be true?

f(0) = 4 f(0) = −4 f(4) = 0 f(−4) = 0

_______________________________________

Solution:

f(x) is a polynomial.

(x - 4) is a polynomial of f(x).

By converse of factor theorem: If (x - a) is a factor of f(x), then, f(a) = 0.

On comparing (x - 4) with (x - a), we get,

a = 4

So,

f(a) = 0

=> f(4) = 0

Answer:

s + a = 2503s + 5a = 1050

Step-by-step explanation:

Let s and a represent the numbers of student and adult tickets sold. The system of equations that can be written from the given information is ...

  s + a = 250 . . . . . . total of tickets sold

  3s +5a = 1050 . . . dollar value of tickets sold

_____

The solution is (s, a) = (100, 150). 100 student tickets and 150 adult tickets were sold.

∠ABC = 54°

Step-by-step explanation:

an inscribed angle is 1/2 the size of an incenter angle.

so:

∠AMC = 2(∠ABC)

10x - 12 = 2(4x + 6)

10x - 12 = 8x + 12

simplify:

2x = 24

x = 12

Irene offered answer equivalent to the original expression

Given :

Mrs. Crosland asked students to factor the expression 28x - 8

The student are given some expression . To find correct expression , we need to factor the given expression

[tex]28x-8[/tex]

Both 28 and 8 are divisible by 4

Lets factor out 4 from the given expression.

When we factor out 4, then we divide each term by 4

[tex]28x-8\\4(\frac{28}{4} -\frac{8}{4} )\\4(7x-2)[/tex]

The students offered the answers shown

Carlos: 2(14x - 4)

Answer:

  J  3/4 cup

Step-by-step explanation:

Step 1: read and understand the question.

  The question is giving you amounts of flour and 2 types of sugar.

  The question is asking for a difference between two quantities:

the amount of flour (2 1/4 cups)the combined amount of sugar (3/4 cup white, 3/4 cup brown)

Step 2: determine the relations you need to use to solve the problem

   You need the combined amount of sugar, which you find by adding the quantities of each of the kinds.

  3/4 cup white + 3/4 cup brown = 6/4 cup sugar combined

 You need the difference of that quantity from the quantity of flour, which you find by performing subtraction:

  flour - sugar = (2 1/4) - (6/4) . . . . cups

Step 3: Use your knowledge of arithmetic.

  (2 1/4) -(6/4) = 9/4 -6/4 = (9 -6)/4 = 3/4

Step 4: Answer the question that was asked.

  The difference between the flour and sugar amounts is 3/4 cup.

thabo rounded the number of marbles to the nearest 5. His answer was 340. write down 2 possible numbers for the actual number of marbles.​

Answers

Answer:

338 or 335 they both get rounded of to the nearest 5

2 possible numbers for the actual number of marbles 338 and 335, are rounded to the nearest 5.

What is rounding off of numbers?

We round off numbers to make them easier to remember and it also keeps their value approximately to the place it has been rounded off.

To round off any number to any place we'll look for the digit next to that place and if it is equal to or greater than 5 we'll add one to the previous digit and make all the digits after it zeroes and if the digit is less than 5 we do not add one to the preceding digit and simply make all the digit after it to zeroes.

Given, Thabo rounded the number of marbles to the nearest 5 and his answer was 340.

Therefore, 2 possible numbers for the actual number of marbles could be

Whether it's 338 or 335, both numbers are rounded to the nearest 5.

The new patio at Tonya's house is 5 yards long by 10 feet wide. She is going to cover the patio with square bricks that measure 1 foot on each side. If each brick costs $4, how much will Tonya pay for the bricks? A rectangle that is five yards long and ten feet wide A. $600 B. $120 C. $150 D. $200

Answers

Answer:

A

Step-by-step explanation:

Steps to take to determine the answer

Because the length is in yards, it has to be converted to footFind the area of the patio using the length and width measured in footDetermine the area of the square brickMultiply the cost of the brick by the area

1 yards = 3 foot

5 x 3 = 15 foot

Area of a rectangle = length x breadth

15 x 10 = 150 ft^2

Cost = 150 x 4 = $600

Answer:

y = -1/5x - 1

Step-by-step explanation:

The line crosses the y axis at -1, making it the y-intercept.

Since the line is going downwards from left to right, we know that it is a negative slope.

The line goes down one and 5 right. That makes the slope -1/5.

The equation is y = -1/5x - 1
