I am sure you are getting it now just do the following:

     1.Subtract 4 from both sides of the equation.

     2.Simplify.

     3.Subtract  x from both sides of the equation.

     4.Then Simplify.

    5.Multiply all terms by the same value to eliminate fraction denominators.

    6.Simplify agiain

    7.Divide both sides of the equation by the same term

    8.Simplify again

    9. And finally we made it ...Solution

Hope this really does help!

Answer:

1

Step-by-step explanation:

The y-coordinate is 4, so we count 4 units up the y-axis from the x-axis. You can also look at it as counting 4 units up from the origin. Then, we look at graph C. When y=4, when we're 4 units above the x-axis, x=1 since the point on the line falls 1 unit to the right of the y-axis.

You would have to divide 195 by both 15 and 12 to get both hours mowing and hours babysitting.

195 / 15 = 13

195 / 12 = 16 1/4

now if you put the answers in place of b and m you would get (15*13) + (12*16.25) = 195

Answer: 195

Conclusion: Sophia gets over payed

Step-by-step explanation:

One hour of babysitting costs $15          One hour of mowing costs $12

Let the of hours babysitting be x,            Let the hours of mowing be y,

                                                                   $195÷2=$97.5

$195-$49.5 = $145.5                                 $97.5 - 12 X 4 =$49.5

∴ Total money Sophia got for                     ∴ Total money Sophia got

    baby sitting is $145.5.                                         mowing is $49.5.

Now,                                                            Now,      

15 X x = $145.5                                           $12 X y = $49.5

       x = [tex]\frac{145.5}{15}[/tex]                                                          y = [tex]\frac{49.5}{12}[/tex]

       x = 9.7                                                            y = 4.125

∴ Sophie babysitted for                        ∴ Sophia mowed for 4.125 hours.

     9.7 hours.

Note:

You can check if your answer is correct like this:

Multiply 9.7 by $15 ( you will get $145.5 as the answer)

Then, multiply 4.125  by $12 (you will get $49.5 as the answer)

Lastly, add the answers together.($145.5 + $49.5 which will give the answer

                                                                                                            as $195)

And boom you got the same answer as written in the question.

It's just a small trick to check if your answer is correct.

I hope this will help you!!!

Step-by-step explanation:

because a positive times a negative will always equal a negative.

Answer: b

Step-by-step explanation:

1. mean) 4+10+3+1=18 18÷4=4.5 median) 1x,3,4,10x 3+4=7 7+1=8 8÷2=4 mode) there is no mode in the list as no values are repeated

2. mean before) 25+25+22+30=102 102÷4=25.5 mean after) 25+25+22+30+15=117 117÷4=29.25 median before) 22x,25,25,30x 25+25=50 50÷2=25 median after) 15x,22x,25,25x,30x

HOPE THIS HELPS

-Todo <3

Step-by-step explanation:

9/4=2.25

180/2.25=80

Answer:

48

Step-by-step explanation:

for this we need to figure out the rate of change and the price for one notebook, we can take any point on the graph like 12 notebooks for $27

first divide the price by the amount of books

27 / 12 = 2.25

and BOOM step one is done, we now know the cost for one notebook, not to find out how many notebooks $108.00 will give you, we will divide again, this time we divide the goal cost by the unit cost

108.00 / 2.25 = 48

and that is the amount of notebooks that $108.00 will get ya, please comment if you have questions about the process or how it can be used in similar situations

take care mah m8s :D

Answer:

42<h<60

H is greater than 42 but less than 60, 42 is less that h and h is less than 60

(I don’t understand what the question is asking for so just correct me if I answered it incorrectly)

According to this inequality, the H must be at least 60 inches taller than 42 inches.

According to the mathematical definition of inequality, neither side is equal. In mathematics, inequality occurs when a non-equal comparison between two expressions or numbers results from the relationship. In this expression, the equal sign "=" can be substituted for any of the inequality symbols greater than (>), less than (<), greater than or equal to (≥), less than or equal to (≤), or not equal to (≠). Mathematically can take many forms, including polynomial inequality, rational inequality, and absolute value inequality.

Given h > 42 and h < 60,

where h is height in inches,

the equation for inequality is,

42 < h < 60

which says that the height of a person should be more than 42 inches and less than 60 inches.

Hence the equation is 42 < h < 60, height should more than 42 inches and less than 60 inches.

1. Linear

2.Linear

3. Not a function

4. Exponential

5. Exponential

6. Quadratic Function

7. Absolute Value

8. Quadratic Function

For starters, the basic of a function is that for every input there is it's own [nonrepeating] output.

In mathematics, the term linear function refers to two distinct but related notions. We usually describe this as y=mx+b.

Exponential functions are a function of the form {f(x)=ab^{x}} where b is a positive real number, and the argument x occurs as an exponent.

Quadratic function, a quadratic polynomial, a polynomial of degree 2, or simply a quadratic numeral.

An absolute value function contains an algebraic expression within absolute value symbols (the value of a number is its distance from 0 on the number line.) To graph an absolute value function, choose several values of x and find some ordered pairs.

Functions -as stated before have one output for every input. They cannot repeat the same output as the horizontal line would.

Answer:D. n = 9

Step-by-step explanation:

n/12 = 3/4 // - 3/4

n/12-3/4 = 0

1/12*n-3/4 = 0 // + 3/4

1/12*n = 3/4 // : 1/12

n = 3/4/1/12

Answer:

25 yd = L

Step-by-step explanation:

The formula for the area of a parallelogram of length L and width W is

A = L * W.

Here we know that A = 125 yd^2, which (from the formula) equals (L)(5 yd).

                                                            125 yd^2

Solving for the length, L, we get L = --------------- = 25 yd = L

                                                                  5 yd

The speed is faster of Diego is 5.5m/sec

We have the following information available from the question is:

Lin and Diego both ran for 10 seconds, each at their own constant speed. Lin ran 40 meters

and, Diego ran 55 meters.

We have to find the Who was moving faster?

Now, According to the question:

We use the formula:

Speed = distance/time

We have :

Speed of Lin is = 40/10 = 4m/sec

Speed of Diego = 55/10 = 5.5 m/sec

So, The speed is faster of Diego.
