What is the domain of this function?

Answer:

The correct answer is option 2: -1

Step-by-step explanation:

In order to check if a number is zero of a function or not, the numer is put into the function in plave of variable. If the answer is zero thent he number is zero of the function and if the answer is not zero the given number is not a zero of the function.

Given function is:

[tex]x^3+x^2+x+1[/tex]

Putting x=1

[tex]=(1)^3+(1)^2+1+1\\=1+1+1+1\\=4[/tex]

1 is not zero of the function.

Putting x = -1

[tex]=(-1)^3+(-1)^2+(-1)+1\\=-1+1-1+1\\=0[/tex]

-1 is zero of the given function.

Hence,

The correct answer is option 2: -1

Answer:

When somethins is parallel it never crosses each other, this means the new equation has to have the same slope but, since y=-3 is a straight line we just have to make the new line also a straight line, maknig sure it passes through (2,5).

To do this make y equal the y-coordinate of the points it needs to pass through. This would make the answer y=5

Answer:

f(m) = 25-2m

Step-by-step explanation:

Let m be the number of maps Jan buys.

Let f(m) be the amount she has left after buying maps

f(m) = 25-2m

Equation to represent the amount she will have left of she buys maps is

f(m) = 25-2m

"An equation is a mathematical statement that is made up of two expressions connected by an equal signs."

Given

Cost of each map = $2

Total amount Jan have = $25

Let m be the number of maps Jan buys.

Let f(m) be the amount she has left after buying maps

f(m) = 25-2m

Thus, equation to represent the amount she will have left of she buys maps is f(m) = 25-2m.

Answer:

f(x) = (x + 4)² - 4

Step-by-step explanation:

Write the equation f(x) = x² + 8x + 12 in vertex form by completing the square:

f(x) = (x² + 8x + (8/2)²) + 12 - (8/2)²

Simplify:

f(x) = (x² + 8x + 16) + 12 - 16

Subtract to find the 'k' value:

f(x) = (x + 4)² - 4. This is the equation in vertex form.

Answer:

y=8x2+8x−12

Answer:

252

Step-by-step explanation:

because there are 14 chairs at each table => there are: 294/14= 21 (tables)

two chairs will be removed from each table => the number of chairs removed are: 21.2 = 42 (chairs)

the chairs  will be left in the cafeteria are: 294 - 42 = 252( chairs)

When two chairs will be removed from each table, then there would be 252 chairs left in the cafeteria.

Dividend = Divisor × Quotient + Remainder.

For given question,

total number of chairs = 294

there are 14 chairs at each table.

So, to find the number of tables in the cafeteria we need to divide total number chairs by 14.

The number of table would be,

= 294/14

= 21

This means, there are 21 tables.

If we remove two chairs from each table, then number of chairs at each table would be 14 - 2 = 12

So, the total number of chairs left in the cafeteria would be,

= 21 × 12

= 252

Hence, there will be 252 chairs left in the cafeteria.

Answer:

2. B) n > 2

4. B) -3

5. C) 1[tex]\frac{1}{2}[/tex]  (Which is equal to 1.5)

8. D) x > [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

2. -6n < -12

To solve for n, divide by -6. When divide by a negative, you flip the sign.

n > 2

4. 2(n + 5) [tex]\geq[/tex] 4 and 3(n - 1) < 3

Divide by 2 for the first inequality and divide by 3 for the second inequality.

n + 5 [tex]\geq[/tex] 2 and n - 1 < 1

Now subtract 5 and add 1

n [tex]\geq[/tex] -3 and n < 2

Since the inequality says and, both equations have to be true when n is plugged in. We can see that -3 works, since it is equal to -3 AND is less than 2.

5. 4x - 7 [tex]\geq[/tex] [tex]\frac{-12x+14}4}[/tex]

Multiply by 4 to both sides

16x - 28 [tex]\geq[/tex] -12x + 14

Now add 12x and add 28.

28x [tex]\geq[/tex] 42

Divide by 28 to get x.

x [tex]\geq[/tex] 1.5

So the answer is C.

8. 3(2x - 1) > 4x - 2

For this one, distribute the 3 to the numbers in the parentheses.

6x - 3 > 4x - 2

Add 3 and subtract 4x.

2x > 1

Divide by 2.

x > [tex]\frac{1}{2}[/tex]

Explanation;

A prime number is a positive integer that has exactly two positive integer factors, 1 and itself.

Note that the definition of a prime number doesn't allow 1 to be a prime number:

1 only has one factor, namely 1.

Prime numbers have exactly two factors, not "at most two" or anything like that. When a number has more than two factors it is called a composite number.

Prime Numbers between 1 and 200 are;

{2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103, 107, 109, 113, 127, 131, 137, 139, 149, 151, 157, 163, 167, 173, 179, 181, 191, 193, 197, 199}

So the above listed examples are prime numbers because they have only two factors.

The maximum difference will occur when the smallest 'a' value is subtracted from the largest 'b' value:

  9 -2 = 7

The minimum difference will occur when the largest 'a' value is subtracted from the smallest 'b' value:

  7 -4 = 3

So, the possible range of values of b-a is ...
