Answer: A

Step-by-step explanation:

I had this question on my test yesterday lol

The system of equation will be ". a + c = 90 8a + 5c = 525"

Let the number of adults tickets be represented by a

Let the number of children tickets be represented by c.

Since 90 total tickets were sold, this can be represented by the equation:

a + c = 90

Since adult movie tickets cost $8 each while the children pay $5 for a ticket, and total cost spent is $525, this will be:

8a + 5c = 525

Therefore, the correct option is A.

The value of x is equal to 8.

Given the following equation;

[tex]x + y = 12[/tex]  .....equation 1

[tex]x = 2y[/tex]       .....equation 2

To find the value of x, we would solve the system of equations by using the substitution method to determine the value of y;

Substituting eqn 2 into eqn 1, we have;

[tex]2y + y = 12[/tex]

[tex]3y = 12\\\\y = \frac{12}{3}[/tex]

y = 4

Next, we would solve for the value of x;

From equation 2;

[tex]x = 2y\\\\x = 2(4)[/tex]

x = 8

Therefore, the value of x is equal to 8.

Answer:

$330,000

Step-by-step explanation:

The selling price per unit is $15

The variable cost per unit is $5

Units sold is $33,000

The contribution margin can be calculated as follows

(15-5)×33000

= 10 × 33000

= 330,000

Hence the contribution margin is $330,000

Answer:

Step-by-step explanation:

4). This is an exponential function.

5). Let the equation of this function is,

    f(x) = a(b)ˣ

    Since, two points (-1, 4) and (0, 6) are lying on the graph of the function,

    For (-1, 4),

    4 = a(b)⁻¹

    4 = [tex]\frac{a}{b}[/tex] --------(1)

    For (0, 6),

    6 = a(b)⁰

    a = 6

    From equation (1),

    4 = [tex]\frac{6}{b}[/tex]

    b = [tex]\frac{6}{4}[/tex] = 1.5

    Therefore, equation of the function will be,

    f(x) = 6(1.5)ˣ

6). Now the value of f(-4) will be,

    f(-4) = 6(1.5)⁻⁴

           = 1.185

Step-by-step explanation:

x + 3 = 0

x = - 3

f(x) = 2x³ - 4x² - 28x + 6

f(- 3) = 2(- 3)³ - 4(- 3)² - 28 x (- 3) + 6

= 2 x (- 27) - (4 x 9) + 84 + 6

= - 54 - 36 + 90

= - 90 + 90

= 0

Therefore,

x + 3 is factor of 2x³ - 4x² - 28x + 6

Answer:

4 1/2 tiles are needed to cover this area

Step-by-step explanation:

Mathematically, the area of a parallelogram is the product of the base and the height

We have this as;

24 * 10 = 240 cm^2

So the area of a tile is this

The number of tiles that will cover the given area will be;

1080/240 = 4.5 tiles

Answer:

y = 5x + 1

Step-by-step explanation:

Hello There!

Equations that have no solutions are parallel

So the line we are going to create an equation for has the same slope as the line drawn  

To find the slope we do change in y divided by change in x

as y goes 5 x goes up 1

so the slope is 5/1 or 5

The requirements for the equation is it has to go through the points (0,1)

The ordered pair listed is the y intercept so the equation would be

y = 5x + 1

Answer:

Undefined slope
