Answer:
hi! so the way I do this is I hold my hand out and do a ninja chop! I know this is weird but it's helpful or you could remember right and left!
anyways your line is "chopping" or leaning right which means you use your right hand not your left to recreate this line right is positive!
so this would be positive if it was negative it would go to the left and if you're using your hand to "chop" like a knife then you would use your left hand because your line would lean to the left
not sure if the chop method works for everyone but you could always remember right is positve and left is negative
update: found this weird picture but this is basically what I mean when I say chop LOL

Answer: D and B
Step-by-step explanation:
The range (answered by D) is only the multiples of 15 between 0 and 60 as it is impossible to pay an amount different than the correct inclinations of 1/15 per candy. For example, it is impossible to pay 12.345421 dollars for a candy.
A similar solution applies for the domain. Only integers(whole numbers) are valid as you cannot buy 1.2862 of a candy.

A block of wood is in the shape of a rectangular prism with dimensions (n+5) cm, (n+8) cm, and (n+14) cm. All faces of the block are painted, and then the block is cut into 1 cm cubes using parallel cuts to each face. If exactly half of the cubes have no paint on them, find the total number of cubes.
Answers
Answer:
The total number of cubes in the rectangular prism are 1,120 cubes
Step-by-step explanation:
The given parameters are;
The dimensions of the rectangular prism block of wood = (n + 5), (n + 8), and (n + 14)
The volume of the block of wood = (n + 5)×(n + 8)×(n + 14) = n³ + 27·n² + 222·n + 560
The quantity of the 1 cm cubes that have no paint = 1/2 of the total quantity = 1/2 the volume of the original cube
The cubes that have paint on them are the surface cubes, we have;
One layer of cube is removed from each of the eight sides, therefore, we have the dimensions of the cube rectangular prism that have no paint on them given as (n + 5 - 2), (n + 8 - 2), and (n + 14 - 2), which gives the dimensions as (n + 3), (n + 6), and (n + 12);
Therefore, we have
2 × (n + 3)×(n + 6)×(n + 12) = (n + 5)×(n + 8)×(n + 14)
2 × (n + 3)×(n + 6)×(n + 12) - (n + 5)×(n + 8)×(n + 14) = 0
Which gives;
n³ + 15·n² + 30·n - 128 = 0
n = 2
n = -17/2 - √(33)/2 = -5.6277
n = √(33)/2 - 17/2 = -11.3722
Therefore, given that the smallest dimension of the painted prism = (n + 5), the possible value for n = 2
The volume of the rectangular prism = (n + 5) × (n + 8) × (n + 14) = (2 + 5) × (2 + 8) × (2 + 14) = 1120 cm³
Given that the cuts are 1 cm³ each, the total number of cubes in 1,120 cm³ = 1,120 cubes.

What is the equation of the line parallel to 8x - 16y= -14 and passing through (3, 0)?
Answers
Answer:
8x -16y = 24
Step-by-step explanation:
8x - 16y= -14
A parallel line (i.e. same slope) will be: 8x - 16y= c
We have to find the value of "c".
If it passes through (x, y) = (3, 0) ⇒ 24 - 0 = c,
so equation is 8x -16y = 24

Find the irrational number between 0.3101 and 0.3333
Answers
Answer:
π/10
Step-by-step explanation:
Irrational Numbers
The irrational numbers are identified because, unlike rational numbers, they cannot be expressed as fractions, i.e., as the result of a division between two integers.
If a number is expressed with a limited number of decimals, it's always possible to write it as a rational.
For example, number 1.2319 can be written as 12319/10000.
Even if the number has an unlimited decimal expression, it could be expressed as rational if the decimal part is periodic. Number 2.33333... is rational because it's equivalent to the fraction 7/3.
We need to find an irrational number between 0.3101 and 0.3333.
Any number within the range with unlimited non-periodic decimals will do:
0.3189567363.... is a good example.
We'll choose the number
π/10 since π is a known irrational number and π/10=0.3141592... lies in the given interval.

Write the equation in point-slope form of the line that passes through the given point and with the given slope m.
(3,-4); m = 6
O y + 4 = 6(x - 3)
O y + 3 = 6(x-4)
O y + 4 = 6(x +3)
O y - 4 = 6(x-3)
Answers
Answer:
y + 4 = 6(x - 3)
Step-by-step explanation:
Point-slope form: y - y1 = m(x - x1)
Given: m = 6, (3, -4)
(x1, y1) = (3, -4)
Input the given values into the equation for point-slope form:
y - (-4) = 6(x - 3)
y + 4 = 6(x - 3)
The equation written in point-slope form is: y + 4 = 6(x - 3)

A cleaning company charged $125 to clean a 2500 square foot house. The same company charged $146 to clean a 3200 square foot house. Write an equation in slope-interceptiom to represent the total cost, y, to clean a house with x square feet. Then, find the total cost to clean a house that is 4500 square feet.
Answers
Answer:
The cost is y = $185
Step-by-step explanation:
Let us have points spelt out here
(2500,125) and (3200,146)
The general form of a straight line equation is;
y = mx + b
where m is slope
So to calculate the slope in this case, we have
m = (146-125)/(3200-2500)
m = 21/700 = 0.03
So we have the equation as
y = 0.03x + b
To get b, we use any of the two points
Let us use (2500,125)
So we have
125 = 0.03(2500) + b
125 = 75 + b
b = 125-75
b = 50
So the complete equation of the line is;
y = 0.03x + 50
So here, we want to find the cost of a house with 4500 square feet
simply substitute 4,500 for x
y = 0.03(4500) + 50
y = 135 + 50
y = $185
