Part A: What Is The Initial Value Of The Function? What Does It Mean In The Context Of The Situation?part

Answers

Answer 1

Answer:

Initial value = 10, slope = 4

Step-by-step explanation:

Initial value is the point where x takes its lowest value. In this case it is x = 0 and y = 10. Rate of change is the slope at a given point. Because this is a first order equation graph the slope is always the same. And in this case it is 4 as for every 1 unit of x the y goes 4.

What two numbers multiply to -24 and add to -5?

Answers

-8 and 3
(-8 * 3 = -24)
(-8 + 3 = -5 )

The two numbers that multiply to -24 and add to -5 are 3 and -8

How to determine the numbers

From the question, we have the following parameters that can be used in our computation:

Product = -24

Sum = -5

Let the numbers be x and y

So, we have

xy = -24

x + y = -5

Let x be 3 and y be -8

So, we have

3 * -8 = -24

3 - 8 = 5

The above equations are true

Hence, the numbers are 3 and -8

Answer:

Step-by-step explanation:

Simplify the left side.

Multiply both numerator and denominator by the conjugate of the denominator:

(√3 - 1)/(√3 + 1) = (√3 - 1)(√3 - 1)/(√3 - 1)(√3 + 1) =(√3² - 2√3 + 1)/(3 - 1) =(10 - 2√3)/2 = 5 - √3

You want to rent a television Company A charges $50 per week plus a one-time fee of $15. Company B charges 130 per week plus a one time fee of $55. After
how many wears are the total costs the same at the companies?

Answers

Company A: y = 50x + 15
Company B: y = 130x + 55

Set the equations equal to each other and solve for x (number of weeks).
50x + 15 = 130x + 55

Subtract 50x from both sides:
15 = 80x + 55

Subtract 55 from both sides:
-40 = 80x

Did you have a typo? The companies will never have the same cost because company B costs so much more and weeks cannot be negative.
