Step-by-step explanation:

Answer:C->-4<=X<=6

Second answer:A -4<=y<=4

Third answer: yes

According to the given graph, the domain of the function is -4 to 6, So Option C is correct

Function is a relation between a set of inputs and a set of outputs which are permissible. In a function, for particular values of x we will get only a single image in y. It is denoted by f(x).

Vertical line test:-

Whenever we want to check whether a given expression is a function or not we can apply a vertical line test, in this test we check for a single image of x , we are getting a single image or more.

If we get more images then it will not be a function.

For example, let us take, y² = 4ax

y = ±√4ax

For single value of x we get two values of y

Hence, it will not be a function.

Given that,

The graph,

Which has values of x in the interval of -4 to 6

And the value of y in the interval of -4 to 4

So, for any function all the values of x for which function is defined

that interval is a domain of a function

And, for input of values of x all the output values of y are known as range of a function

Domain:  -4 ≤ X ≤ 6

Range:   -4 ≤ Y ≤  4

Hence, the domain is -4 ≤ X ≤ 6

Answer:

He paid $2.35 for each pair of socks.

An equation using the variable S is

$77.99 = 9S + (3 × $8.28) + $32

Step-by-step explanation:

Let S be the cost of a pair of socks

From the question, Mark purchase nine pairs of socks, that is, the total cost of the pairs of socks is 9S

He purchase three packages of undershirts for $8.28 each; the total cost of the three packages of shirt will be 3 × $8.28 = $24.84

and he also purchase a pair of pants for $32

Since he spent a total of $77.99, we can write that

$77.99 = 9S + (3 × $8.28) + $32

Now, we can determine S, the cost of a pair of socks

$77.99 = 9S + (3 × $8.28) + $32

$77.99 = 9S + $24.84 + $32

$77.99 = 9S + $56.84

9S = $77.99 - $56.84

9S = $21.15

S = $21.15/9

S = $2.35

Hence, he paid $2.35 for each pair of socks.

Answer:

x = 1

Step-by-step explanation:

4x+7(3x-3) = 9-5x (equation)

4x+21x-21 = 9-5x (simplify)

25x-21 = 9-5x (combine like terms)

30x-21 = 9 (add 5x to each side)

30x = 30 (add 21 to each side)

x = 1 (divide each side by 30)

The factors of -24 which should be used to factorize the given quadratic equation are -8 and 3.

It is required to factorize the quadratic equation [tex]x^2-5x - 24[/tex] using the factors of -24.

The required combination of factors should be -8 and 3 because,

[tex]-8+3=-5\\-8\times3=-24[/tex]

Now, factorize the quadratic equation as,

[tex]x^2-5x - 24=x^2-8x+3x-24\\=x(x-8)+3(x-8)\\=(x-8)(x+3)[/tex]

Therefore, the factors of -24 which should be used to factorize the given quadratic equation are -8 and 3.

Answer:

Step-by-step explanation:

Correct steps to find the value of 'a' should be,

Braulio's synthetic division should be,

-1  |     1       5         a          -3           11

               -1        -4        (4 - a)     (a - 1)  

         1      4     (a - 4)     (1 - a)     (a + 10)

Here remainder is (a + 10).

So (a + 10) = 17 ⇒ a = 7

Braulio Incorrectly found a value of 'a' because he should have used (-1) instead of 1.

Zahra's calculation by remainder theorem should be,

p(x) = x⁴ + 5x³ + ax² - 3x + 11

p(-1) = (-1)⁴ + 5(-1)³ + a(-1)² - 3(-1) + 11

      = 1 - 5 + a + 3 + 11

      = (a + 10)

Since, remainder of the solution is 17,

(a + 10) = 17 ⇒ a = 7

Zahra incorrectly found the value of 'a' because she incorrectly solved the powers to (-1).

Answer: incorrectly, should have used -1 instead of 1

incorrectly, incorrectly applied the powers to -1

Answer:

8!

Step-by-step explanation:

I'm sure you're still really smart, you just don't understand it :)

Those two bars mean the absolute value of whatever's inside of them. Absolute value is always positive, so if you had 34 inside of the bars, it would still be positive 34.

Now that we know what those bars mean, the expression is really this:

1 + 7

I'm sure you can solve that :)

Answer:

y = -4x - 3

Step-by-step explanation:

y = -4x + 2

Substitue Y and X and turn 2 into b(or y intercept)

5 = -4(-2) + b

Solve for b

5 = 8 + b: subtract 8 from both sides

-3 = b

substitute for 2 with same slope(to keep parrallel)

y = -4x - 3
