Janice receives $.40 per pound for 1 to 99 pounds of aluminum cans he recycles. he receives $.50 per pound if you are cycles mor
Ilya [14]

Answer:

M=\left\{\begin{matrix}0.4x &x\leq99 \\ 0.5x &x>100 \\ \end{matrix}\right.

Step-by-step explanation:

<u>Function modeling</u>

Real-life situations often require the help of mathematics to model numerically what happens when the variables involved can change. It could even be used to predict some expected outcomes from those models.

The problem states Janice receives $.40 per pound when he recycles less or equal than 99 pounds of aluminum. If x is the number of recycled pounds, then the amount of money he receives is

M=0.4x

We also know that if he recycles more than 100 pounds of aluminum, the pay increases to $0.5 per pound. In that case, the amount of money is

M=0.5x

This is a case where the function is defined differently depending on the conditions of the input variable x. It's called a piecewise function. The function can be written as

M=\left\{\begin{matrix}0.4x &x\leq99 \\ 0.5x &x>100 \\ \end{matrix}\right.

Note the function is not well constructed because there is a gap for x=100 where M is not defined. If we establish that for 100 pounds the payment is $0.5, then the second piece would include x=100

Sum of x and it’s square is equal to y times z
ludmilkaskok [199]

The algebraic representation of the statement is x + x² - yz = 0

<h3>What are algebraic expressions?</h3>

Algebraic expressions brings the idea of creating or expressing numbers using letters or alphabets without specifying their actual values.

From the information given , we have that;

  • sum of x and it's square = x + x²
  • Equal to y × z

Now, let's equate the expressions;

x + x² = y × z

x + x ² = yz

Let's make into quadratic form

x + x² - yz = 0

Thus, the algebraic representation of the statement is x + x² - yz = 0

Rewrite the equation y – 4x = –9 in slope-intercept form.
Vera_Pavlovna [14]
The answer to your question is A. Y= -4x-9 because is you look at the pre written equation it shows that 4x is negative and that 9 is negative too. Also, if you rewrite an equation you have to isolate Y. Therefore A is the correct answer

Uni made a model of a 1970 Ford Mustang using a scale of .5 inches = 9 in. If the actual car is 15 ft long, how long is the mode
kykrilka [37]

Answer:

The model car is 10 inches long

Step-by-step explanation:

To solve this question, we use conversion of units

Feet to inches.

Each feet has 12 inches.

The car is 15ft long.

So the car has 15*12 = 180 inches.

.5 inches = 9 in.

Rule of three

.5 inches - 9 inches

x inches - 180 inches

9x = 180*0.5

9x = 90

x = \frac{90}{9}

x = 10

The model car is 10 inches long
