: Y = 1/3x - 1
:
M = y2 - y1/ x2-x1
M = 6 - (-3) / 1 - (-2)
Y = 1/3x + b
Then substitute one of the points into the equation
-2= 1/3(-3) + b
-2 + 2 + b = 1/3(-3) +b - b + 2
-b = 1/3(-3) + 2
-b = 1
b = -1
Y = 1/3x - 1
Then i plugged it into

Notice that v points into the third quadrant since both of its components are negative. If you want a vector to point in the same direction, it would need to have the same sign on its components. So C is the correct choice.
The factor of 1/√80 comes from normalizing the vector v. Its norm/magnitude is
|v| = √((-4)² + (-8)²) = √(16 + 64) = √80
so the unit vector that points in the same direction as v is simply v / |v|.

The cost of an article including 15% for taxes is ghc ghc138. What is the cost of the article without taxes
Answer:
Cost of article before tax is 120.
Step-by-step explanation:
It says cost of an article including 15% tax is 138.
So, let the cost of article without tax as 'x'
So, we can set up equation as
x+15%(x)=138
Simplify it
x+0.15x=138
1.15x=138
Divide both sides by 1.15
x=120
So, cost of article before tax is 120.
Troy has an album that has 400 hockey cards. Each page of the album holds 4 hockey cards. If 19% of the album is empty, how many pages are filled with hockey cards?
Answer:
81 pages
Step-by-step explanation:
From the information given :
Total hockey cards = 400
Cards per page = 4
Number of pages = 400 /4
Number of pages in album = 100
% of album which is empty = 19%
% filled = 100 - 19 = 81%
81% of 100
0.81 * 100 = 81 pages

1. A scientist is growing cell cultures and examining the effects of various substances on them as part of his research. The culture in one petri dish increases according to the expression +47 + 4 for timet in minutes. Another increases according to 12 + 2t+4. He needs to feed all the cells equally, so he needs to know the expression for the total number of cells in both dishes because the food is proportional to the total number of cells. Find the expression.

A single die is rolled one time What is the probability of rolling an even number or a 5?
Answer: 4/6 or 2/3
Step-by-step explanation:
Step-by-step explanation:
Total sample space , n(s) = 6
Favourable cases of rolling even number,
n(e) = 3
Favourable cases of rolling 5 , n(f) = 1
Probability of rolling an even number or a 5 is
= p(e) + p(f)
= n(e) / n(s) + n(f) / n(s)
= 3 / 6 + 1 / 6
= 4 / 6
= 2/3

9 1/2 yards x 19 1/4 yards
Answer:
(9 1/2) * (19 1/4) = 1463/8 = 182 7/8
Step-by-step explanation:
Conversion a mixed number 9 1/2
to a improper fraction: 9 1/2 = 9 1/2
= 9 · 2 + 1/2
= 18 + 1/2
= 19/2
To find a new numerator:
a) Multiply the whole number 9 by the denominator 2. Whole number 9 equally 9 * 2/2
= 18/2
b) Add the answer from previous step 18 to the numerator 1. New numerator is 18 + 1 = 19
c) Write a previous answer (new numerator 19) over the denominator 2.
Nine and one half is nineteen halves
Conversion a mixed number 19 1/4
to a improper fraction: 19 1/4 = 19 1/4
= 19 · 4 + 1/4
= 76 + 1/4
= 77/4
To find new numerator:
a) Multiply the whole number 19 by the denominator 4. Whole number 19 equally 19 * 4/4
= 76/4
b) Add the answer from previous step 76 to the numerator 1. New numerator is 76 + 1 = 77
c) Write a previous answer (new numerator 77) over the denominator 4.
Nineteen and one quarter is seventy-seven quarters
Multiple: 19/2
* 77/4
= 19 · 77/2.4
= 1463/8
