Answer:
The slope of f(x) is equal to the slope of g(x).
Step-by-step explanation:
The question is incomplete. Here is the complete question.
Compare the slopes of the linear functions f(x) and g(x) and choose the answer that best describes them.
a graph of a line labeled f of x passing through 0, negative 1 and 3, 1
x g(x)
0 2
3 4
6 6
Slope is defined as the change of the y axis to the z axis of a plane.
Slope = ∆y/∆x
Slope = y2-y1/x2-x1
For f(x) with coordinates (0, -1) and (3,1)
x1 = 0, y1 = -1, x2 = 3 and y2 = 1
Slope of f(x) = 1-(-1)/3-0
Slope = 1+1/3
Slope = 2/3
For g(x), we will choose any two of the coordinates from the table. Using the coordinates (3,4) and (6,6)
x1 = 3, y1 = 4, x2 = 6 and y2 = 6
Slope of g(x) = 6-4/6-3
Slope of g(x) = 2/3
It can be seen that the value of both slopes are equal. Hence, the slope of f(x) is equal to the slope of g(x) is the correct option.
Answer:
The answer is C. The slope of f(x) is equal to the slope of g(x).

Answer:
4 inch
Step-by-step explanation:
given that the ratio of the floor plan with that of the actual measurement =
1 inch : 2 feet....................(1)
so we have to find the length of the house on the floor plan if the actual measurement is 8 feet.
using eq (1), we can say that the length on the floor plan will be half of the actual length.
therefore if the actual length of the house is 8 feet, then
length of the house on the floor plan = 8/2
= 4 inch
Answer:
We need 4 inches
Step-by-step explanation:
We can use ratios to solve
1 in x inches
---------- = -------------
2 ft 8 ft
Using cross products
1 * 8 = 2 x
Divide each side by 2
8 /2 = 2x/2
4 = x
We need 4 inches

many men can build a home in 20 days?
A) 18
B) 36
C) 45
D) 180
Answer:
2.222.........
Step-by-step explanation:
10 : 90

You can pick one or the other to have as your answer
===========================
Explanation:
The formula you use is
A = pi*r^2
The radius is r = d/2 = 10/2 = 5
So,
A = pi*r^2 = pi*5^2 = pi*25 = 25pi
is the exact area
Replace pi with 3.14 to get 25*pi = 25*3.14 = 78.5
which is the approximate area
To get a better approximation, you would use more decimal digits of pi.

whats the squareroot of 144 needs to be simplified
Answer:
12
Step-by-step explanation:
The square root of any number is basically asking "what number multiplied by itself will equal this number?"
Usually you memorize these, but there's also a quick way to do it.
We know that [tex]10\cdot10=100[/tex], so the square root must be greater than 10.
We also know that [tex]15\cdot15=225[/tex], so the square root must be less than 15.
A good mid point between these numbers is 13. Let's see what 13 squared is:
[tex]13\cdot13=169[/tex]
So it's a bit less than 13. Let's try 12.
[tex]12\cdot12=144[/tex]
So 12 is the square root of 144.

Answer:
f(x) = 8(1/2)^x.
Step-by-step explanation:
According to the graph, there is a point at (0, 8) and (1, 4).
That means that when x = 0, y = 8.
8 = a(b)^0
1a = 8
a = 8
That means that a = 8, and when x = 1, y = 4.
4 = 8(b)^1
4 = 8b
8b = 4
b = 4/8
b = 1/2
So, f(x) = 8(1/2)^x.

4 pumps can fill 800l of water in 20 min. In how many
minutes will 12 pumps fill 600l of water?
a) 6 min b) 5 min
c) 4 min d) 8 min
Answer:
Step-by-step explanation:
One pump will fill 200l in 20 minutes
So the rate of filling per pump will be 10l/minute (200/20)
Let the number of minutes it will take to fill the 600l be x minutes
Now, since the rate of filling per pump is 10 l/minute
Then in x minute, they would have filled 10l/minute * x = 10x liters
So it is now this 10x liters that will be equal to 600
To find x, we simply divide
10x = 600
x= 600/10
x = 6 minutes

write an equation of the perpendicular bisector of the segment joining a(-2,3) and b(4,-5).
A) 3x+4y=7 B) 3x-4y=-7 C) 3x-4y=7 D) -3x-4y=7 E) 4x-3y=7
Answer:
C) 3x - 4y = 7
Step-by-step explanation:
The midpoint of AB is
M( (-2 + 4)/2, (-5 + 3)/2 ) = M(1, -1)
Line AB has slope:
(3 - (-5))/(-2 - 4) = 8/(-6) = -4/3
Slopes of perpendicular lines are negative reciprocals.
A perpendicular to line AB has slope 3/4.
The perpendicular to line AB that passes through the midpoint of segment AB is the line we want.

Answer:
$402
Step-by-step explanation:
Hello!
If you made 3.80 an hour and worked 40 we can multiply these to find the total amount you earned.
3.80 * 40 = 152
You also made 250 in tips so we add that to the total
152+250 = 402
The answer is $402

When using ANOVA, the sum of squares within is: Group of answer choices Showing the difference between the groups Effect variance Error variance Showing the differences caused by the independent variable
Answer:
When using ANOVA, the sum of squares within is: Showing the difference between the Total SS and Between SS known as Error variance
Step-by-step explanation:
Within SS is also known as Error sum of squares . It is calculated by finding the difference between Total Sum of Squares and Between Sum of Squares
with the given degrees of freedom.
Within SS = Total SS - Between SS
Where
Total SS= ∑∑X²- C. F
Between SS= ∑T²j/r - C.F
Correction Factor = CF = Tj²/n
So the correct answer would be
Showing the difference between the Total SS and Between SS also known as Error variance.
7x-y= 22
4x + 2y = 10
can someone help plz?
Answer:
x = 3
y = -1
Step-by-step explanation:
Based on the fact that our have two variables and two equations, I'm going to assume you are trying to find the values of x and y.
For these two equations, let's first find the value of x using the equation elimination method.
We're going to eliminate the y variable by multiplying the first equation by 2 and then adding that new equation to the second equation.
7x - y = 22 ==> 14x - 2y = 44
4x + 2y + (14x - 2y) = 10 + (44)
18x + 0y = 54
x = 3
Now we plug the value of x back into one of the equations to find the value of y.
7x - y = 22
7(3) - y = 22
-y = 22 - 21
y = -1
So our values are as follows:
x = 3
y = -1

Sandy had test scores of 20, 25, 17, 22, and 21. What is the average (mean) score. On the next 3 test Sandy's score were 24, 24, and 23. What is her mean now?
Answer:
a) First Average mean = 21
b) Current mean = 22
Step-by-step explanation:
Formula For mean =
Sum of Terms/ Number of terms
a)Sandy had test scores of 20, 25, 17, 22, and 21.
Number of terms = 5
Mean = (20 + 25 + 17 + 22 + 21)/5
= 105/5
= 21
b) On the next 3 test Sandy's score were 24, 24, and 23
To calculate this current mean, we will add the first 5 test scores, with this current 3 test scores and then find the average.
Mean = (20+ 25+ 17 +22 +21 + 24 + 24 + 23)/8
Mean = 176/8
Mean = 22
On a coordinate plane, a curved line with minimum values of (negative 0.8, negative 2.8) and (3, 0), and a maximum value of (1.55, 10.8), crosses the x-axis at (negative 2.5, 0), (0, 0), and (3, 0), and crosses the y-axis at (0, 0). Which interval for the graphed function contains the local maximum? [–3, –2] [–2, 0] [0, 2] [2, 4]
Answer:
(0,2)
Step-by-step explanation:
So C
The correct option is option C: [0,2] contains the local maximum.
What is the local maximum?Local maximum is the relative maximum point where it is maximum within the neighborhood of that point.
From the graph shown in the picture, it is clear that,
the curved line touches the x axis at the point R(-2.5, 0), O(0, 0), and Q(3, 0).
similarly, the curved line touches the y-axis at O(0,0).
the graph has local minima at P(-0.8,-2.8) and Q(3, 0).
So the graph is below the x-axis between the point (-2.5, 0), (0, 0).
the graph has local maxima at S(1.55,10.8).
So the graph is above the x-axis between the point (0, 0), and (3, 0).
so the local maximum occurs at S(1.55,10.8).
From the option, it is clear that the point (1.55,10.8) lies in the interval [0,2].
Therefore [0,2] contains the local maximum.

An office supply store recently sold a black printer ink cartridge for $14.99 and a color printer ink cartridge for $20.99. At start of a recent fall semester, a total of 42 of these cartidges was sold for a total of $695.58. How many of each type were purchased?
Answer:
B = 31, C = 11
Step-by-step explanation:
Let B be the number of Black printer ink cartridges and C be the number of color printer ink cartridges.
42 were sold in total, hence,
B+C= 42 ------------(1)
Also, its given that
14.99 B+20.99C= 695.58 ------(2)
Multiplying (1) by 20.99,
14.99 B+14.99 C= 629.58 ------(3)
Now, subtracting (3) from (2),
14.99 B+20.99C= 695.58
14.99 B+14.99 C= 629.58
------------------------------------
6 C = 66
C= 66/6
C = 11
We know, B+ C= 49
Hence B = 42- 11 = 31
B = 31
Hence, number of Black printer ink cartridges = 31 and color printer ink cartridges = 11 .
