At a store, a hat has a regular price of x dollars. During a sale, the price of the hat is discounted by 20%. The expression 0.8x describes the discounted price, in dollars, of the hat. Which expression also describes the discounted price, in dollars, of the hat?

Answers

Answer: D) x - 0.2x

Step-by-step explanation:

The hat has a regular price of x dollars.

This price is reduced by 20% so the relevant expression for the discount is; 20% * x or; 0.2x

The discounted price will be the price of the hat less the discount which means the formula will be;

= Price - discount

= x - 0.2x

You prepare 10 scoops of dog food for 5 dogs, and prepare 16 scoops of dog food for 8 dogs. What
is the constant of proportionality for the amount of dog food to the number of dogs? How many
scoops of dog food should you prepare for 6 dogs?

Answers

Answer:

12 scoops of dog food are needed for 6 dogs,

Step-by-step explanation:

Proportions

The number of scoops of dog foods and the number of dogs are proportional variables.

We are given that 10 scoops of dog foods are used for 5 dogs. This gives a proportion of 10/5=2 scoops per dog.

We also know that 16 scoops are used for 8 dogs. The proportion is also 16/8=2 scoops per dog.

Thus, the constant of proportionality is 2.

For 6 dogs, you need to prepare 2*6 = 12 scoops of dog food.

12 scoops of dog food are needed for 6 dogs,

Answers

Answer: The answer is: -2

Step-by-step explanation:

Here, suppose

(5,-2)=(x1, y1)

(-7,22)=(x2, y2)

Now, use the slope equation to find slope(m).

     y2-y1=m(x2-x1)

or,m=y2-y1/x2-x1

After this, just substitute the values from above.
