Answer:
So standard form is 2x-3y=6
Slope intercept form is y=2/3x-2
What is the slope of a line perpendicular to the line whose equation is 2x-10y=100
Answer:
-5
Step-by-step explanation:
To find the perpendicular line, first rearrange this into slope intercept form.
y= mx + b
2x - 10y = 100
-10y = -2x +100
y = 1/5x - 10
The slope of a perpendicular line has a slope that is the receipt I’ll of and opposite of this line. The slope here is 1/5 so flip it and you have 5/1. It will also be negative since that slope was positive.
1/5 —> 5/1 —> -5

A bike is on sale for 45% off of the regular price. If the sale price is $299.75, what was the original price?
Answer:
the original price is 545$
Step-by-step explanation:
299.75$ : 55$ = x : 100
55x = 299.75 x 100
55x : 29975

a) Solve 3(x – 5) = 18
Answer:
x = 11
Step-by-step explanation:
3(x-5) = 18
Step one: Distrubute 3 to the numbers in the parenthesis.
3x - 15 = 18
Step two: Add 15 on both sides
3x = 33
Step three: Divide by 3 on both sides
x = 11

Answer:
$324.37
Step-by-step explanation:
First question already answered in other post.
Second Question:
Original price before discount and tax: $354
Discount: 15%
100% - 15% = 85% = 0.85
0.85 * $354 = $300.90
Tax: 7.8%
100% + 7.8% = 107.8% = 1.078
1.078 * $300.90 = $323.37
Answer: $324.37

You have two identical boxes which an interior dimensions of 8.0x8.0x8.0. You completely fill one of the boxes with wooden spheres that are 1.6 in diameter. The other box gets filled with wooden cubes that are 1.6 cm on each edge. After putting the lid on the filled boxes, you then measure the density of each. Which one is more dense?
Answer: The one filled with wooden cubes.
Step-by-step explanation:
First, the box filled with spheres will have empty space, this is for how spheres are, so independent of the radius of the sphere, we will always have some empty space inside the box.
In the case of the cubes, this does not happen. Furthermore, the dimension of the box are 8cm by 8cm by 8cm, and the cubes have a sidelength of 1.6cm
We know that:
1.6cm*5 = 8cm
Then we can perfectly fill the box with the wooden cubes (such that there is no empty space like in the previous case).
Because this box has no empty space and is filled with the same material as the other box, we can conclude that this box will have a larger mass than the one filled with spheres.
And we know that:
density = mass/volume.
Both boxes have the same volume, but the box with cubes has a larger mass, then the box with cubes will have a larger density.

what is the measure of <A in the triangle below
Answer:
∠A = 62°
Step-by-step explanation:
∠ACB = 180 - 116 = 64°
∠A + ∠B + ∠C = 180°
(3x - 13) + (2x + 4) + 64 = 180°
3x + 2x - 13 + 4 + 64 = 180°
5x + 55 = 180°
5x = 180 - 55
5x = 125
x = 125/5
x = 25
∠A = 3x - 13
∠A = 3(25) - 13
∠A = 75 - 13
∠A = 62°

find the value of v
Answer:
v = 38
Step-by-step explanation:
A parallelogram is a quadrilateral in which both sides are the same. That means that 2v is equal to v + 38, and you can solve this. You would get that 2v = v + 38, which means that v = 38.
A grocery store sells 6 bottles of water for $4 and 18 bottles for $10. Is the cost of the water proportional to the number sold?
Proportional
Nonproportional
Answer:
Non Proportional
Step-by-step explanation:
Make a proportion:
For example say you want to test out how many bottles of water you can buy for $10
Proportion:
4 - 6
10 - ?
Solve: 10×6÷4=15
So technically, you could only get 15 bottles for $10. Therefore, this is a non proportional problem.

Answer:
Tn = 8n - 2
Step-by-step explanation:
Given the arithmetic sequence
6, 14, 22, 30, 38
The nth term is expressed as;
Tn = a +(n-1)d
a is the first term = 6
d is the common difference = 14 - 6 = 22 - 14 = 8
Substitute into the formula;
Tn = 6 + (n-1)(8)
Tn = 6 + 8n-8
Tn = 8n - 2
Hence the nth term of the sequence is 8n-2
Solve and check
y = 3x - 10
y = 2x - 5
Answer:
This is the subtraction method
Y -3X = -10
(-Y -2x = -5) -Y + 2X = 5
Y -3X = -10
-Y + 2X = 5
-X = -5
X = 5 Now fill in the 5 for X and Y = 5
Answer:
x = 5, y = 5
or
(5, 5)
Step-by-step explanation:
they both equal y so they also equal each other.
3x - 10 = 2x - 5
3x - 2x = -5 + 10
x = 5
substitute x for 5
y = 3x - 10
y = 15 - 10
y = 5
edit, whops forgot to check
just plug the variables in with their values and see if it makes sense:
y = 2x - 5
5 = 2*5 - 5
5 = 10 - 5
5 = 5
since 5 does equal 5, the solution is correct.

The average person in the United States drinks 767 cups of coffee annually. How many quarts of coffee is that? Show your work. ( do not comment if you do not know or I will report )
Answer: 191.75 quarts.
Step-by-step explanation:
We know that:
1 quart = 4 cups.
Then:
1 cup = 1/4 quarts.
this means that 1 cup, is equal to 1/4 quarts.
Then 767 cups is equal to 767 times 1/4 quarts.
The change of units is simply:
767 cups = 767*( 1/4 quarts) = 191.75 quarts.
