Answers

Answer:

Step-by-step explanation:

Find the slope = -2/1

Find the y-intercept = 5

Go to graph

put a dot at (0,5)

since it's a negative slope you will go up 2 and left 1

draw your line

_________________________________________________

Find the slope = 3/1

Find the y-intercept = 0

go to graph

Put a dot at (0,0)

Since it is a positive slope you will go down 3 and left 1.

To find the slope and y-intercept use this formula=

y=mx+b

m=slope

b=y-intercept

If 15 mL of a solution contains 75 mg of medication, how many mg of medication are in 60 mL of solution?

Answers

Given:

15 mL of a solution contains 75 mg of medication.

To find:

How many mg of medication are in 60 mL of solution?

Solution:

We have,

Medication in 15 mL of a solution = 75 mg

Medication in 1 mL of a solution = [tex]\dfrac{75}{15}[/tex] mg

                                                     = [tex]5[/tex] mg

Medication in 60 mL of a solution = [tex]60\times 5[/tex] mg

                                                        = [tex]300[/tex] mg

Therefore, 60 mL of a solution contains 300 mg of medication.

Purplemath

First you learned (back in grammar school) that you can add, subtract, multiply, and divide numbers. Then you learned that you can add, subtract, multiply, and divide polynomials. Now you will learn that you can also add, subtract, multiply, and divide functions. Performing these operations on functions is no more complicated than the notation itself. For instance, when they give you the formulas for two functions and tell you to find the sum, all they're telling you to do is add the two formulas. There's nothing more to this topic than that, other than perhaps some simplification of the expressions involved.

Given f (x) = 3x + 2 and g(x) = 4 – 5x, find (f + g)(x), (f – g)(x), (f × g)(x), and (f / g)(x).

To find the answers, all I have to do is apply the operations (plus, minus, times, and divide) that they tell me to, in the order that they tell me to.

(f + g)(x) = f (x) + g(x)

= [3x + 2] + [4 – 5x]

= 3x + 2 + 4 – 5x

= 3x – 5x + 2 + 4

= –2x + 6

(f – g)(x) = f (x) – g(x)

= [3x + 2] – [4 – 5x]

= 3x + 2 – 4 + 5x

= 3x + 5x + 2 – 4

= 8x – 2

(f  × g)(x) = [f (x)][g(x)]

= (3x + 2)(4 – 5x)

= 12x + 8 – 15x2 – 10x

= –15x2 + 2x + 8

Answer:

b = 12

Step-by-step explanation:

Using the Pythagorean Theorem:

a² + b² = c²

You can identify that 12√12 is the hypotenuse, as it is opposite to the right angle.

So:

12² + b² = (12√2)²

144 + b² = [(12√2) (12√2)]

144 + b² = (12 × √2 × 12 × √2)

144 + b² = (144 × 2)

144 + b² = 288

b² = 144

√b² = √144

b = 12

Perla buys the star necklace that is originally $49.95 but is currently on sale for 62% off. If she gets an additional 20% off, what is the final price of the necklace?

Answers

Answer:

Step-by-step explanation:

Remark

It's not 82.

You have to take the 62% off and then follow it with 20% from the new price.

Solution

62%

If you get a reduction of 62%, it means that you pay 100% - 62% = 38% of the marked price of $49.95.

38% price =49.95 * 62/100

38% price = 3096.9 / 100

38% price = $30.97

20%  Reduction

20% more means that you pay 100% - 20% = 80%

20% more reduction = 30.97 * 80/100

20% more reduction = 2478/100

20% more reduction = 24.78

Conclusion.

Your final price before taxes is $24.78
