Answer:

-1=41

0=-8

1=-15

2=-22

so these are the answers

Step-by-step explanation:

it must have 2 solutions, as the absolute value makes negative and positive values equal.

so, 2 approaches : positive and negative.

1. positive

(x + 2) + 4 = 11

x + 6 = 11

x = 5

2. negative

-(x + 2) + 4 = 11

-x - 2 + 4 = 11

-x + 2 = 11

-x = 9

x = -9

so, the third answer (x = 5, -9) is correct.

Step-by-step explanation:

Hope that helps!

Step-by-step explanation:

for a function every valid x value must have exactly 1 y value. several x values can have the same y value assigned but never can a x value have multiple y values assigned.

the valid x values for m are -3. -2, -1, 1, 2, 3.

and indeed, every one of these values has exactly one y value out of the possible 1, 4, 9 values.

so, m is a function.

but the inverse function turns the meaning of x and y upside-down. x becomes y and y becomes x.

and now we see that for the inverse the x value of 1 has two assigned y values (-1, 1).

the same for 4 (-2, 2) and 9 (-3, 3).

so, the inverse is NOT a function.

Answer:

Step-by-step explanation:

Let the cupcake cost = c

Let the milkshake cost = m

4c + 3 m = 23

2c + 4m = 24        multiply this equation by 2

2(2c + 4m = 24)

4c + 8m =     48        Now put the first equation underneath this one

4c + 3m = 23       Subtract

       5m = 25         Divide by 5

        m = 25/5

         m = 5

Use 2c + 4m = 24

m = 5

2c + 4*5 = 24            Combine

2c + 20 = 24             Subtract 20 from both sides

2c = 24 - 20

2c = 4                        Divide by 2

c = 4/2

c = 2

Answer:

Area = 1/10

Step-by-step explanation:

Since the Area of Triangle = 0.5*Base*Height

So, for our Problem

Base=3/5 km  ,  Height=1/3 km

Area =  0.5*Base*Height =   [tex]\frac{1}{2} *\frac{3}{5} *\frac{1}{3}[/tex]

Area = [tex]\frac{1}{2} *\frac{1}{5}=\frac{1}{10}[/tex] Square Kilometers

Answer:

−11c4+5c2+3c−6  degree is 4

Step-by-step explanation:

The purchase price of Wynona’s boots is 85.5% of the original price.

It is given that

The marked price of boots = $85.79

The percentage is a relative value indicating the hundredth parts of any quantity.

Price after a discount of 10% = [tex]85.79 - 85.79*10/100 = 77.211[/tex]

Price after another discount of 5% = [tex]77.211-77.211*5/100 = 73.35[/tex]

[tex]\frac{PurchasePrice}{OriginalPrice}*100 =\frac{73.35}{85.79}*100 = 85.5[/tex]

Therefore, The purchase price of Wynona’s boots is 85.5% of the original price.

Step-by-step explanation:

Answer:

20%

Step-by-step explanation:

$34 - $27.20 = $6.80

[tex]\frac{6.80}{34} = 0.2[/tex]

0.2 x 100 = 20%

:]

The percent of discount in the tag is, 20%.

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

The price on the tag was $34, but Mia paid $27.20 before tax.

Here, The discount price = $34 - $27.20

                                       = $6.8

Hence, The percent discount = 6.8 / 34 × 100

                                              = 20%
