Fill out the table as we did in class for the following:
a) y= 3x + 1
b) y= 2x - 5
c) y = - 2x - 2
All between the values of - 3< x < 3
Answer:
Step-by-step explanation:
Construct a 2-columned table for each function. Arbitrarily choose x values to go into the first column, values between -3 and +3:
Example, for y = 3x + 1:
x y = 3x + 1 (x, y)
--------------------------------
-2 3(-2) + 1 (-2, -5)
0 3(0) + 1 (0, 1)
1
2
x is the "independent variable." You choose the values, subject to the requirement that -3 < x < +3. The function will return the y values, which are dependent upon the inputs x. This will give you a good number (e. g., 5) points to plot. Draw a line through these points to obtain a graph of
y = 3x + 1. And so on. You need to go through this procedure once for each of the 3 given functions.
You buy 1.65 pounds of oranges and 2.25 pounds of plums. Oranges and plums sell for the same price per pound. The total cost, after using a 65¢-off coupon, is $3.64. If c represents the cost of the fruit in dollars per pound, what equation could you use to find the value of c?
Answer:
C=(3.64+0.65)/(1.65+2.25)

hello my friend is from 7th grade she need help with her math 5200 at 49% for 3years??
Answer:
At the end you will have 12,844$ and you have earned 7644$
Step-by-step explanation:
49% 49 times the money 5,200$ = 254,800 divided by 100 = 2548 in 1 year.
Times 2548 by 3 and get 7644$ ( Interest Earned ) add that by original money and get 12,844$ (Money In Total)
How many sides does a polygon have if the sum of the interior angles is 900∘?
Answer:
7 slides
Step-by-step explanation:
Sum of exterior angles of any polygon is always 360∘, it can never be 900∘. Hence, there cannot be any polygon like this.
It appears that by error the word "exterior" has been mentioned. In case sum of interior angles is 900∘,
total sum of all the angles is 900∘+360∘=1260∘.
But sum of each pair of interior and exterior angles add up to 180∘
we have 1260∘180∘=7 such pairs
and hence polygon has 7 sides.
Answer:
It's a heptagon, so 7 sides

Pls help me!!!! Im stuck!!!
Answer:
has no solution.
Step-by-step explanation:
you can see that the two equations are almost identical except for the fact that one is multiplied by 7, but it isnt completely multiplied correctly so there would be no solutions.
Answer:
infinite solutions
Step-by-step explanation:
you can solve this by the elimination method. take the rover a equation and multiply it by -7 and then combine the equations. when you do this, you can see that either side equals 0 which means that there are infinite solutions.
-7(y= 1.5x - 6) which equals the equation below
-7y= -10.5x-42 then combine the other equation
7y=10.5x+42 and that equals

u/9+11 at u = -18 can u please show steps?
Answer:
u = -261
Step-by-step explanation:
Subtract 11 from both sides:
u/9 + 11= -8
u/9 + 11 - 11 = -18 -11
u/9 = -18 - 11
u/9 = -29
u/9 9 = -29 9
u= - 29 9
u = -261

If you borrow $5000 at an interest rate of 8% for 9 years how much interest will you pay? (I got $3600 but I don't know if its right)
Step-by-step explanation:
Principal:- $5000
Rate= 8%
Time = 9 years
Interest = P×R×T/100
= 500×8×9/100
= 5×8×9
= 40×9
= 360
Hence, Interest = $360.

Which of the following pairs of functions are inverses of each other?
Answer:
THE ANSWER IS B
Step-by-step explanation:
IT JUST MAKES SENSE TO CHOOSE B
The option D pairs of functions are inverses of each other.
What is the function?A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.
To find the inverse of a function, write the function f(x) as a function of x and then solve for x as a function of f(x).
For option A,
f(x) = 2 + ∛x
To solve for x,
∛x = f(x) - 2
x = (f(x) - 2)³
That is also the inverse So,
g(x) = (x -2)³ "Not correct"
For Option B,
f(x) = x/6 + 8
To solve for x,
x/6 = f(x) -8
x = 6f(x) - 6 *8
That is also the inverse So,
g(x) = 6x - 6 *8 "Not correct"
For Option C,
f(x) = 7/x - 9
To solve for x,
7/x = f(x) +9
x = [tex]\frac{7}{f(x) +9}[/tex]
That is also the inverse So,
g(x) = [tex]\frac{7}{x +9}[/tex] "Not correct"
For Option D,
f(x) = 5x - 11
To solve for x,
5x= f(x) + 11
x = (f(x) + 11)/5
That is also the inverse So,
g(x) =(x + 11)/5 "correct"
Thus, the option D pairs of functions are inverses of each other.

Find the missing dimension. Use the scale factor 1 : 12.
Answer:
3.84m
Step-by-step explanation:
If the scale for this Water tower is 1 : 12 then this means that for every 1cm of the model, the actual water tower has 12cm. Therefore, in order to find the actual depth of the water tower we first need to multiply the depth of the model by 12.
32cm * 12 = 384cm
1 cm is equal to 0.01 m , therefore we now have to multiply the depth of the actual water tower which is in cm by 0.01 to get the actual depth in meters
384 * 0.01 = 3.84m

Answer:
x = 5
Step-by-step explanation:
These triangles are similar, so they are in proportion to each other. Because of this we can say [tex]\frac{2.5}{3.5}[/tex] (the lengths of the vertical sides) = [tex]\frac{x}{7}[/tex] (the lengths of the hypotenuses). If we solve by cross-multiplying the numbers and then dividing we get x = 5.

What is the volume, in cubic centimeters, of the cylinder?
A 602.88
B 150.72
C 50.24
D 301.44
Answer:
A
Step-by-step explanation:
The base of your cylinder has a radius of 4 cm, its area is 16 × 3.14, or 50,24 square centimeters. If that same cylinder is 12 cm tall, its volume is 50,24 × 12 = 602,88 cubic centimeters.

Find the value of x
Answer:
1
Step-by-step explanation:
As per circle theorem rule, ∠GDE is twice than ∠GFE
10x +94 = 2 × (x+51)
10x + 94 = 2x + 102
8x = 8
x = 1
∠GDE= 10x+94° = 104°
∠GFE= x + 51° = 52°
A farmer has 500 acres of arable land on which he wants to plant potatoes and corn. The farmer has $40,000 available for planting and $30,000 for fertilizer. Planting 1 acre of potatoes costs $90, and planting 1 acre of corn costs $50. Fertilizer costs $30 for 1 acre of potatoes and $80 for 1 acre of corn. (a) Find a system of inequalities that describes the number of acres of each crop that the farmer can plant with the available resources. (Let x and y be the numbers of acres of potatoes and corn, respectively.)
Answer:
90x+ 50 y ≤ $40,000------ A
30x+ 80y ≤ $ 30,000------- B
x + y ≤ 500 --- C
Step-by-step explanation:
Let x and y be the numbers of acres of potatoes and corn, respectively.
Then according to the given conditions
90x+ 50 y ≤ $40,000------ A
30x+ 80y ≤ $ 30,000------- B
x + y ≤ 500 --- C
where both x and y equal to or greater than zero and cannot take a value less than zero.
x + y ≤ 500 --- C
gives us an idea that the total arable land is less or equal to 500 acres.
90x+ 50 y ≤ $40,000------ A
tells us that the total cost of planting potatoes and corn is less or equal to $ 40,000
30x+ 80y ≤ $ 30,000------- B
tells us that the total cost of fertilizers for potatoes and corn is less or equal to $ 30,000
In each of these x and y cannot have negative values or less than zero.
