m =( Y2 - Y1)/ (X2-X1)

m =( 3-(-5))/ (-6-3)

m = - 8/9

I am assuming you meant a slope of 9/8 in your original question, so the points perpendicular to I are answer D.

Perpendicular means the slope is opposite reciprocal of your first slope given.

An exercise class costs $9 per class. Seven students are planning to take 12 classes. How much will the students pay in all.

lions [1.4K]

Answer:

Let's assume

Ms.Meyer used to bring x students for the cost $9 per student

so, total cost = 9x

now, we are given

For ticket cost $6 , she can brings 47 more students

so, total students =x+47

total cost =6*(x+47)

now, we are given total costs are same for both

we get

we can solve for x

Subtract both sides by 6x

Divide both sides by 3

so, Ms. Meyer brings 94 students to theater.........Answer

The stock of Company A gained 2% today to $27.03. What was the opening price of the stock in the beginning of the day?

Luden [163]

Answer:

The price of the stock in the beginning of the day was $26.5.

Step-by-step explanation:

This question can be solved using a rule of three.

The initial stock of the company, that we want to find, was 100% = 1.

$27.03 is an increase of 2%, so it is 100+2 = 102% = 1.02%. So

$27.03 - 1.02

$x - 1

$1.02x = 27.03$

$x = \frac{27.03}{1.02}$

$x = 26.5$

The price of the stock in the beginning of the day was $26.5.
