Answer: (8,-7)

Step-by-step explanation: Since you are reflecting over the x-axis, the x coordinate stays the same, but the y coordinate does change. Instead of it being negative, the eight would become positive.

the cost of a candle varies directly with the volume of the candle. If a candle with a volume of 80cm^3 costs $12, what would be

ivanzaharov [21]

First, you need to find out how much will the candle cost per volume. If a candle with a volume of 80cm^3 costs $12, the price of the candle per cm^3 would be: $12/80cm^3= $0.15/cm^3

Then the price of a candle with 120 cm^3 volume would be:120cm^3* $0.15/cm^3= $18

Suppose y varies directly with x, and y = 12 when x = 2. What direct variation

neonofarm [45]

Answer:

$y=24$

Step-by-step explanation:

Given:

$y=kx$

Substitute:

$\left \{ {{y=12} \atop {x=2}} \right.$ into $y=kx$

$12=k\times2$

Swap the sides:

$k\times2=12$

Divide both sides of the equation by the coefficient of variable:

$k=\frac{12}{2}$

Cross out the common factor:

$k=6$

Find the equation of the function:

$y=6x$

Substitute:

$y=6\times4$

Calculate the product or quotient:

$y=24$

Sydney has a rectangular pool as shown in the figure. The pool is 6 feet deep throughout. mc017-1.jpg How much water is needed t

densk [106]

The amount of water that is needed to fill the pool is equal to the volume of the pool.

The pool is rectangular, with uniform depth so the volume of pool will be the product of its length , width and depth.

Thus,

Volume = 25 x 18 x 6 = 2700 ft³

This means, 2700 ft³ water is needed to fill the pool.
