Write the equation of a line that is perpendicular to y= 3x-2 and that passes through the point (-9,5)

Write The Equation Of A Line That Is Perpendicular To Y= 3x-2 And That Passes Through The Point (-9,5)

Answers

Answer 1

Answer:

Ans: y = (-1/3)x + 2

Step-by-step explanation:

Perpendicular lines have slopes whose product is -1.  The slope given in

y = 3x - 2

is -3.

The slope of the perpendicular line will be m, and m needs to satisfy the equation

3 * m = -1

Hence m = -1/3.

Our perpendicular line is thus

y = (-1/3)x + b

for some constant b.

We are told that the perpendicular line goes through the point (-9,5).  If so, then the following must hold:

5 = (-1/3)(-9) + b

= 3 + b

b = 2

Ans: y = (-1/3)x + 2

You are buying cupcakes for a school party. They are in a package of 6 for $8.50. You have budgeted no more than $40 to spend. If cost of the cupcakes is a function of the number of packages purchased, what is the largest element of the domain in this situation?

Answers

Answer: Largest element in the domain is 4

The largest number of packages you can buy is 4

======================================================

Explanation:

1 package costs 8.50*1 = 8.50 dollars

2 packages cost 8.50*2 = 17 dollars

3 packages cost 8.50*3 = 25.50 dollars

and so on. In general

x packages cost 8.50*x = 8.50x dollars

where x is a place holder for a positive whole number (1,2,3,...)

The total amount spent is 8.50x and the budget is $40

This means,

[tex]8.50x \le 40\\\\x \le \frac{40}{8.50}\\\\x \le 4.70588\\\\x \le 4\\\\[/tex]

We round down regardless of how close we are to 5.

If x = 4, then 8.50*x = 8.50*4 = 34

While if x = 5, then 8.50*x = 8.50*5 = 42.5

So we see we go over budget if we buy x = 5 packages.

This makes x = 4 the largest in the domain.

Recall the domain is the set of allowed x inputs. In this case, x is a positive whole number (since we can't buy half a package for instance).
