Answer: rises; your slope is positive
Every single time your slope is positive, your line goes upward.
Every time your slope is negative, however, your line goes downward.
Rearrange 9x - 27y = 81 to -27y = -9x + 81 because we want to put our equation into slope intercept so that we can eventually get our 'y' all by itself.
Divide by -27 for every variable.
Your slope intercept form should now look like this; y = 1/3x - 3
Now that we're completely done or that we have 'y' by itself, it's safe to say that our answer is 1/3, which is, also, positive.
Hope this helps, dawg.

Step-by-step explanation:
A certain plant grows 1 1/6 inches every week. How long will it take the plant to grow 6 1/6 inches?
It will take 6.14 weeks for the plant to grow the required length
The growth rate of the plant each week = 1 1/6 inches
Converting the mixed fraction into an improper fraction we multiply the whole number by the denominator and add the numerator to get the improper fraction, therefore
The growth rate of a plant in improper form = 7/6 inches
Required growth rate = 6 1/6 inches
The required growth rate in improper fraction = 43/6 inches
Number of weeks it will take the plant to grow the required length = Required length/Growth rate each week = (43/6)/(7/6)
= 43/7 weeks or 6.14 weeks

The line graph to the right indicates that in 1960, 21% of taxes came from corporate income tax. For the period from 1960 through 2010,
this percentage decreased by approximately 0.32 each year. If this trend continues, by which year will corporations pay zero taxes?
The 21% of taxes and annual percentage decrease of 0.32, using arithmetic progression gives;
The year corporations will pay zero taxes as 2025How can arithmetic progression be used to find the required year?The percentage of tax that comes from corporate income tax = 21%
Amount by which the percentage decreased each year = 0.32
Period during which the tax reduced = Between 1960 and 2010
Required;
The year corporations pay zero taxes.
Solution;
The amount of tax paid each year can be given by the arithmetic progression formula,
[tex] a_{n} = a + (n - 1) \cdot d[/tex]
Where;
a = The first term = 21
[tex] a_{n} = value \: on \: the \: nth \: year[/tex]
d = The common difference = -0.32
When [tex] a_{n} = 0 [/tex], we have;
[tex] 0 = 21 + (n - 1) \times (-0.32) [/tex]
0.32•(n - 1) = 21
n - 1 = 21/0.32 = 65.625
n = 65.625 - 1 = 64.625 ≈ 65
The year the corporations will pay no taxes is 1960 + 65 = 2025
Corporations will pay no taxes in the year 2025

Elizabeth has 4 boxes of 100 toys and 3 toys that aren't in boxes. How many toys does she
have?
Answer:
Elizabeth has 403 toys.
Step-by-step explanation:
The main goal is to figure out how many toys Elizabeth has. So she has 4 boxes and each box has 100 toys. If she has 4 boxes of 100 it mean she have 400 toys but that's not the final answer. she also has 3 toys not in the boxes so we have to add that as well. So if we add 3 toys to the 400 toys we'd get a total of 403. Therefore Elizabeth has 403 toys and that would be our final answer.

21 The average person at rest takes approximately 16 breaths per minute. Approxir many breaths do they take in 70 years of 365 days each? Use a calculator. Write in exponential notation using powers of 10.
A person will take 5.88672 × [tex]10^{8}[/tex] breaths in 70 years.
Here, we are given that on average a person at rest takes approximately 16 breaths per minute.
1 hour = 60 minutes
Thus, in 1 hour a person will take-
60 × 16
= 960 breaths
Now, 1 day = 24 hours
Thus, in 1 day, a person will take-
24 × 960
= 23,040 breaths
Further, 1 year = 365 days
Thus, in 1 year, a person will take-
23,040 × 365
= 8,409,600 breaths
In 70 years, a person will take-
8,409,600 × 70
= 588,672,000 breaths
We can express this in exponential notation as-
5.88672 × [tex]10^{8}[/tex]
Thus, a person will take 5.88672 × [tex]10^{8}[/tex] breaths in 70 years.

Your friend's house is 64 miles from
the beach. Use direct variation to
determine how long it will take to
drive to the beach if you leave from
your friend's house.
The time it would take to drive to the beach if you leave from the friend's house is 1 hour 12 minutes
Calculating timeFrom the question, we are to calculate how long it would take to drive to the beach if you leave from your friend's house
From the given information,
The beach is 80 miles from your house and the drive takes about 1 hour 30 minutes
Distance, d, varies directly with time, t.
d ∝ t
d = vt
Where v is the proportionality constant.
Now, we will find v
d = 80 miles
t = 1.5 hours = 3/2 hours
Thus,
80 = (3/2)v
v = (2 × 80)/3
v = 160/3 miles/hour
Now, we will determine t when d is 64 miles
d = vt
64 = 160/3 × t
t = (64 × 3)/160
t = 192/160 hours
t = 6/5 hours
t = 1 hour 12 minutes
Hence, the time it would take to drive to the beach if you leave from the friend's house is 1 hour 12 minutes

Mr. Arcos is opening a new restaurant. His restaurant has 8 tables with places for 4 people at each table. It also has 4 tables with places for 6 people at each table.
Today he is buying plates for the restaurant. The plates he is buying come in sets of 6 plates. How many sets of plates does he need to buy?
In the given case, we can conclude Mr. Arcos needs to buy 10 sets of plates for his restaurant.
To find out how many sets of plates Mr. Arcos needs to buy, we first need to determine the total number of people his restaurant can accommodate.
There are 8 tables with places for 4 people each, so these tables can seat a total of 8 x 4 = 32 people.
Additionally, there are 4 tables with places for 6 people each, which can seat a total of 4 x 6 = 24 people.
Therefore, the restaurant can accommodate a total of 32 + 24 = 56 people.
Since the plates come in sets of 6, we divide the total number of people (56) by the number of people served by each set (6) to find out how many sets of plates Mr. Arcos needs to buy: 56 / 6 = 9.33 sets. Since plates cannot be bought in fractions, he will need to round up to the nearest whole number. Therefore, he will need to buy at least 10 sets of plates for his restaurant.

The quadratic equation that passes through points (1, - 9) and (0, - 8) is y = x² - 2 · x - 8.
What is the quadratic equation that passes through two points?
Graphically speaking, quadratic equations are parabolas. The quadratic equation in vertex form is described by this formula:
y - k = C · (x - h)²
Where:
(h, k) - Vertex of the parabola.C - Vertex constant.If we know that (x, y) = (0, - 8) and (h, k) = (1, - 9), then the vertex constant is:
- 8 + 9 = C · (0 - 1)²
1 = C · (- 1)²
1 = C
C = 1
Then, the quadratic equation in vertex form is:
y + 9 = (x - 1)²
Whose standard form is:
y + 9 = x² - 2 · x + 1
y = x² - 2 · x - 8
The quadratic equation that passes through points (1, - 9) and (0, - 8) is y = x² - 2 · x - 8.
