Answer:

  • No

Step-by-step explanation:

<u>Given equation:</u>

  • y^2-x^2=16

  • y = ± \sqrt{x^2 + 16}

As we see each x-coordinate has two y-values referenced, it doesn't pass the vertical line test, this is not a function.

Write an explicit formula for an arithmetic sequence whose common difference is -4.5
vovikov84 [41]

For this case we have:


The general formula of the arithmetic sequence is given by:


a_n = a_1 + (n-1) d\\

Where


a_n: Last term


a_1: First term


n: Number of terms


d: Difference


Rewriting according to the given common difference, we have:


a_n = a_1 + (n-1) (- 4.5)

Answer:


a_n = a_1 + (n-1) (- 4.5)

His parents pay Tyler $ 0.75 to do the laundry and $ 1.75 to mow the lawn. In one month, he does the laundry 6 more times than h
zhuklara [117]

Answer: Tyler mowed the lawn 4 times

Step-by-step explanation:

Let x = number of times that he does laundry

Let y = number of times that he mows the lawn

In one month, he does the laundry 6 more times than he mows the lawn. This means

x = 6 +y

Tyler's parents pay him $ 0.75 to do the laundry and $ 1.75 to mow the lawn. If his parents pay him $ 14.50 that month, it means that

0.75x + 1.75y = 14.5 - - - - - - -1

Substituting x = 6+y into equation 1, it becomes

0.75(6 + y) + 1.75y = 14.5

4.5 + 0.75y + 1.75y = 14.5

0.75y + 1.75y = 14.5 - 4.5

2.5y = 10

y = 10/2.5 = 4

x = 6 + y = 6 + 4

x = 10
