Answer:
y = 2x - 8
Step-by-step explanation:
y = 2x + b
8 = 2(8) + b
8 = 16 + b
-8 = b
check work:
6 = 2(7) - 8

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

Last year Stevie was 281/4 inches tall. Since then he has grown 51/5
inches. How tall is Stevie now? Simplify your answer.
T
Answer:
80.45 inches
Step-by-step explanation:
Last year Stevie was 281/4 inches tall, which is: 70.25 inches (70 1/4)
He has grown 51/5 inches which is: 10.2 inches (10 1/5)
70.25 inches (last years height) + 10.2 inches (how many he has grown) = 80.45 inches
Stevie is 80.45 inches tall now.

Answer:
peri=3(3xsq-4x+9)
=9x^2-12x+27
4x - 1 = -13 show the work please
Answer:
x = -3
Step-by-step explanation:
4x - 1 = -13
add 1 to each side
4x = -12
x = -3
Answer:
x = -3
Step-by-step explanation:
Add 1 to both sides to, this gives you 4x = -12. then divide both sides by 4, which would give you x = -3.

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.

3. For each equation, determine if x=2 is a solution. Explain or show your reasoning. Select ALL of those where the x can equal 2. 2 points -2(x - 4) = 4 26/x = 13 - 3.8x = -7.4 4(x - 1) - 3(x - 2) = -8
Answer:
26/x = 13
x = 2
Step-by-step explanation:
2(x - 4) = 4
2x - 8 = 4
2x = 4 + 8
2x = 12
x = 12/2
x = 6
26/x = 13
Cross product
26 = x * 13
26 = 13x
x = 26/13
x = 2
- 3.8x = -7.4
x = -7.4 / -3.8
x = 1.95
4(x - 1) - 3(x - 2) = -8
4x - 4 - 3x + 6 = -8
x + 2 = -8
x = -8 - 2
x = -10

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|.

Answer:
3/4 cm^3
Step-by-step explanation:
Volume = base area * height. Where base area is 1/2*1/2 (As it is a square) and height = 3 cm, so times together get 3/4.
Step-by-step explanation:

Help me with this!!!
Answer:
z = 9
Step-by-step explanation:
JH is a perpendicular bisector of Δ IJK.
Thus the triangle is isosceles with
JK = JI , that is
7z = z + 54 ( subtract z from both sides )
6z = 54 ( divide both sides by 6 )
z = 9

Step-by-step explanation:
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.

Based on the data, how many of 650 ice cream eaters would be expected to prefer vanilla or cookie dough ice cream flavor Number of people vanilla 71 strawberry 22 cookie dough 27 chocolate 83
Answer: 305 people
Step-by-step explanation:
The total number of people sampled is:
= 71 + 22 + 27 + 83
= 209
Out of this 209, the number of people who prefer Vanilla and cookie dough ice cream is:
= 71 + 27
= 98 people
In a sample of 209 people, 98 people would prefer either vanilla or cookie dough. In 650 people, that number would therefore be:
= 98/ 209 * 650
= 305 people
