One example of a mathematical model is an equation that describes the relationship between two quantities.

a. True
b. False

Answers

Answer 1

Answer:

True

Step-by-step explanation:

Linear equations are often used to model the relationship between the dependent variable that is affected by changes in the independent variable.  

For instance, the linear function: f(x) = 2x + 3, where f(x) is the output (dependent variable) depends on the value of the input, x (independent variable).  

Therefore, the correct answer is True.

Answer:

Slope = -4

Step-by-step explanation:

Perpendicular lines have negative reciprocal slopes, which means that multiplying their slopes result in a product of -1. Given the equation, x - 4y = - 12:

Transform the equation into its slope-intercept form, y = mx + b:

x - 4y  = - 12

x - x - 4y = - x - 12

-4y = -x - 12

Divide both sides by -4:

[tex]\frac{-4y}{-4} = \frac{-x - 12}{-4}[/tex]

y =  ¼x + 3  ⇒ (This is the slope-intercept form of the given standard equation, x - 4y  = - 12).

Since the slope of the given equation is ¼, then it means that its negative reciprocal must be - 4:

(¼) (-4) = -1

Therefore, the slope of the line perpendicular to x - 4y = - 12 is - 4.

it’s 1/4 because if you apply the formula you just get that so m=1/4

solve the mystery. it is between 25 and 40.the sum of the digit is 8.the mystery number is not 26​

Answers

Answer:

35

Step-by-step explanation:

Numbers that add up to 8 and number combinations

0 and 8: 80, 08

1 and 7: 17, 71

2 and 6: 26, 62

3 and 5: 35, 53

4 and 4: 44

Since the number must be between 25 and 40, the only possible numbers are 26 and 35

Since 26 is not the answer, the number is 35

There's a big soccer game next month, and Juan has purchased 3 tickets for himself and his siblings. He spent 53 dollars.

Rosie wants to take her family also, but knows her parents and some cousins will want to attend as well. She knows she will have to purchase 9 tickets. Estimate approximately how much money Rosie will likely have to spend on the tickets. Explain your reasoning below.

Answers

Answer:

53 divided by 3 would be $17.66

so 17.66 times 9 would be $158.94

Answer:

158.4 dollars

Step-by-step explanation:

so first of all the three tickets were 53 dollars so we divide the dollars and the no of tickets like this 53÷3 = 17.6 dollars

so since each ticket is 17.6 dollars now we know that Rosie wants to purchase 9 tickets so we will multiply the no of tickets by dollars per ticket like this

9×17.6= 158.4 dollars

and 158.4 is your answer

Jaylo bought a television priced at $349. She received a 20% discount and paid a 7% sales tax. What is the total price of the television? A. $74.69 B. $298.74 C. $348.87 D. $448.12

Answers

Answer:

B

Step-by-step explanation:

349 ---100%

x ------ 20%

x= (349×20)÷100

x=69.8

349-69.8=279.2

279.2 ---100%

x-----7%

x=(279.2×7)÷100

x=19.54

Final result

279.2+19.54=298.74

And final result is B

The total price of the television is B. $297.74

Given that,

Jaylo bought a television priced at $349. She received a 20% discount and paid a 7% sales tax.

Based on the above information, the calculation is as follows:

[tex]= (\$349 \times (1- 0.20) + \$349 \times (1- 0.20) \times 0.07)\\\\= \$279.20 + \$19.544[/tex]

= $297.74
