Answer:

The pool manager pay for each item is $60.6.

Step-by-step explanation:

Given:

A pool manager balances the ph level of a pool.

The price of a bucket of chlorine tablets is $90, and the price of a ph test kit is $11.

The manager uses a coupon that applies a 40% discount to the total cost of the two items.

Now, to find the money the pool manager pay for each item.

The price of a bucket of  chlorine tablets is = $90.

The price of a ph test kit = $11.

So, to get the total price of both items we add both prices:

Total cost of two items = $101.

As, given a coupon that applies a 40% discount to the total cost of the two items.

Now, to get the total cost by applying discount:

Thus, the pool manager pay = $60.6.

Therefore, the pool manager pay for each item is $60.6.

Answer:

equation: y = -3x + 10

Step-by-step explanation:

y = -3x + 11

comparing the formula, y = mx + b

We can determine the slope is -3 and y-intercept is 11.

if the line passes (2,4)

use the formula:

y - y1 = m(x - x1)

y - 4 = -3(x - 2)

y = -3x + 6 +4

y = -3x + 10

Answer:

$6.75 per pound

Step-by-step explanation:

$54 ÷ 8lb = $6.75/lb

or a 1:6.75 ratio/rate

The model to write the rate for this situation is 54 / 8 and the rate is $6.75.

Unit rate is the amount of one quantity for a unit amount of the other quantity.

In other words it compares 1 unit of some quantity with different amount of another quantity.

Given that,

A catering company sells an 8 lb container of food for $54.

We have to find the unit rate for the given situation.

Price for 8 lb container of food = $54

Price for 1 lb container of food = 54 / 8

                                                   = $6.75

This is the required rate, which means that price for 1 lb container of food is $6.75.

Hence, the unit price for the food sold by catering company is $6.75.

Answer:

y = -4x + 14

Step-by-step explanation:

We'll use the slope intercept form: y = mx + b

It is given that the slope of -4, so m will be -4 like this: y = -4x + b

We are also given the coordinates where x = 3 and y =2

2 = -4(3) + b

2 = -12 + b

Add 12 to both sides

2 = -12 + b

+ 12  + 12

b = 14

We end up with y = -4x + 14

Answer:

(-4(x-2))/((x+2)|(x-4)|)

Step-by-step explanation:

You were so close. I stared at your problem for a

long time when you first posted it. I used a graphing utility to experiment. Your denominator was perfect for getting the vertical asymptotes in the right place. The y-intercept worked. The x-intercept was exactly right. I couldn't get the far right piece of the curve to reflect down in the fourth quadrant.

Hours later...suddenly BAM! ABSOLUTE VALUE pops into my head.

I always thought the numerator should be negative, so that middle portion of the curve that looks like a cubic would start "up to the left" and end "down to the right" But those left and right curves should be like mirror images of each other sort of. So I tried the absolute value and it worked! Good luck with your work. Hope this helps a little.

Answer:

1/x+2

Step-by-step explanation:

1/x−2 + 4/4-X^2

​

Factor 4−x^2

1/x−2  +  4/(x−2)(−x−2)

To add or subtract expressions, expand them to make their denominators the same. Least common multiple of x−2 and (x−2)(−x−2) is (x−2)(−x−2).

Multiply :  1/x−2 TIMES −x−2/−x−2

−x−2/(x−2)(−x−2)  +  4/(x−2)(−x−2)

​Since  −x−2/(x−2)(−x−2) and  4/(x−2)(−x−2)  have the same denominator, add them by adding their numerators.

−x−2+4​/(x−2)(−x−2)

Combine like terms in −x−2+4.

−x+2/(x−2)(−x−2)

Extract the negative sign in −x+2.

−(x−2)/(x−2)(−x−2)

Cancel out x−2 in both numerator and denominator.
