Answer:

Let x be the rent for a movie and y is the rent for a video game

The following system of equations:

5x + 2y = 31 (1)

3x + 8y = 56 (2)

Solving the system of equations above we have:

x = (31-2y) / 5 (1) => replace x in (2) 3 ((31-2y) / 5) + 8y = 56 => y = $ 5.5

Replace y = $ 5.5 for (1) => x = ((11 - 11) / 5) = 4

So the rent for a movie is $ 5.5 and the price for renting a video games is $ 4

Does the table represent a linear function? Explain why or why not
OlgaM077 [116]

The table doesn't represent linear function

Step-by-step explanation:

We need to identify if the table represent a linear function or not.

<u>Linear Function </u>

A linear function is defined as a straight line with an x and y intercept and the same slope through the whole line.

Finding the slope of elements in the table:

x      y

0     0

1      1

2     8

3     27

Slope= y/x

Slope = 0/0=0

slope = 1/1 = 1

slope = 8/2 = 2

slope = 27/3 = 9

The function represented is: y=x^3

Since the slope of points x and y in the table is not same, and its graph is not linear.

So, the table doesn't represent linear function

Show all work to factor x4 − 10x2 + 9 completely.
leva [86]

Answer:

(x+1)(x-1)(x+3)(x-3)

Step-by-step explanation:

x4-10x^2+9

Group expression so that the coefficients of the x^2 terms add up to +9.

= x^4 -9x^2   - x^2+9

match coefficients in both groups

= x^4 -9x^2   - (x^2-9)

factor each group

= x^2 (x^2-9) - 1(x^2-9)

now factor out the common factor (x^2-9)

= (x^2-1)(x^2-9)

Finally, factor each quadratic factor

= (x+1)(x-1)(x+3)(x-3)

A menu has three meat choices,
wolverine [178]

Answer:

18 ways

Step-by-step explanation:

Number of Meat choices = 3

Number of Vegetable choices = 3

Number of Desserts = 2

Number of ways dinner can be chosen :

Number of meat choices * Number of vegetable choices * number of desserts

3 * 3 * 2

= 18

Hence, dinner can be chosen in 18 different choices.

Solve the following multiplication problem.<br><br> 11 cu. yd. 17 cu. in. × 135
Gekata [30.6K]

Answer:

69,286,455 cu inches

Step-by-step explanation:

<u>Step 1: Convert yards to inches</u>

1 cu yard = 46656 cu inches

11 cu yard = y cu inches

<em>Cross multiply</em>

y = 11 x 46656

y = 513216 cu inches

<u>Step 2: Find total inches</u>

513216 + 17 = 513233 cu inches

<u>Step 3: Multiply total inches by 135</u>

513233 x 135 = 69,286,455 cu inches

The base of a solid in the xy-plane is the circle x2 + y2 = 16. Cross sections of the solid perpendicular to the y-axis are semi
Alexus [3.1K]

Answer:

The volume of the solid will be = 134.1 cubic units.

Step-by-step explanation:

The base of a solid has the equation of a circle x² + y² = 16 in the xy-plane. Cross-sections perpendicular to the y-axis of the solid are semicircles.

Therefore, the solid will be the shape of a hemisphere.

Now, the radius of the hemisphere will be 4 units.

{Since the base of the hemisphere is on the xy-plane and have equation

x² + y² = 4²}

Therefore, the volume of the solid will be = \frac{2}{3}\pi  r^{3} = (\frac{2}{3})\times (\frac{22}{7}) \times (4^{3}) = 134.1 cubic units. (Answer)
