Answer:

The slope is 3.

Step-by-step explanation:

A direct variation function will always go through the origin point (0, 0).

Therefore, we have the two points (0, 0) and (-2, -6).

We can use the slope formula to find the slope:

$\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Substitute and evaluate:

$\displaystyle m=\frac{0-(-6)}{0-(-2)}=\frac{6}{2}=3$

Therefore, the slope of the function is 3.

To graph, simply plot (0, 0) and (-2, -6) and draw a line connecting them. This is shown below.

Answer:

y = 2/3x - 3

Slope: 2/3x

Step-by-step explanation:

Slope: 2/3x

y- intercept: (0,-3)

once it goes down it'll be -2/-3x which will go to through (-2,-6) as soon as it goes down from the y-intercept.

equation: y = 2/3x - 3

Kevin Hill deposited 15,483 pennies. He put 50 pennies in each penny roll. How many full rolls did he have?

Flauer [41]

Answer:

309 full rolls

Step-by-step explanation:

Find how many full rolls he had by dividing 15,483 by 50:

15,483/50

= 309.66

Since the question asks for full rolls, the answer has to be a full number.

So, the answer is 309 full rolls

The equation p=100-10t represents the percent p of battery power remaining in a cell phone after t hours

Fantom [35]

Answer:

We have the equation:

P(t) = 100 - 10*t

where t is the number of hours.

at t = 0, we have:

P(0) = 100 - 0 = 100

so at the initial time, we have 100% of the battery power.

Now with this equation we can find the numbers of hours that we have left in our phone, this is finding the time t at which the power left is equal to zero:

P(t) = 0 = 100 - 10*t

10*t = 100

t = 100/10 = 10

So the battery power will last for 10 hours.

To rent a certain meeting room, a college charges a reservation fee of $37 and an additional fee of $5.70 per hour. The chemistr

gulaghasi [49]

Answer: t < 4 hours

Step-by-step explanation:

Renting = $37 + t x $5.70

If $37 + t$5.70 < $59.80

t$5.70 < $59.80 - $37

t$5.70 < $22.80

t < $22.80/$5.70

t < 4 hours

Find the surface area of<br> the prism.

Anton [14]

Answer:

$\text{D. }464\:\mathrm{ft^2}$

Step-by-step explanation:

The surface area of the prism consists of four rectangles and two trapezoids. The sum of the areas of these polygons will give the total surface area of the prism:

Rectangle 1 (top base): $12\cdot 14=168$

Rectangle 2 (bottom base): $6\cdot 14 = 84$

Trapezoids 1 and 2 (lateral): $2\cdot 9 \cdot 4=72$

Rectangles 3 and 4 (lateral): $2\cdot 14\cdot 5=140$

Thus the total surface area is equal to

$168+84+72+140=\boxed{\text{D. }464\:\mathrm{ft^2}}$
