How do you know a table is linear?
How do you know an equation is linear?
How do you know a graph is linear?
Answer:
You can tell if a table is linear by looking at how X and Y change. If, as X increases by 1, Y increases by a constant rate, then a table is linear.
An equation is considered linear, if it is in the form of. y = mx + b. where m is the slope of the equation, and b is the y-intercept.
First of all the shape of the graph is a straight line. Every linear graph is nothing more than a straight line so if there is any curves in it, it's not linear. The other way to tell is look at its equation.

determine the quotient of 1/3/4 divided by 2/5
Answer:
First turn any mixed numbers into improper fractions. 1 3/4 would be 7/4. Becuase you multiply the whole number by the denominator and then add the numerator.
So now you have 7/4 divided by 2/5. Whenever you divide, you flip the 2nd fraction upside down... known as the reciprocal. And after that you multiply the first number by the upside down 2nd number.
So now you have 7/4 X 5/2. When multiplying, just multiply the numerators across and the denominators across. As your answer, you get 35/8 or 4 3/8.
Step-by-step explanation:
Answer:
35/8 or 4 3/8
Step-by-step explanation:
whatever works for you. but when you use a caucalater you get 35/8.

Christian wraps a gift box in the shape of a triangular pyramid. The figure below shows a net for the gift box. If all the triangles are equilateral, how much wrapping paper did he use, in square inches?
The amount of wrapping paper he use is 62.4 square inches
How to calculate the surface area of a prismThe formula for calculating the total surface area is expressed as:
Area = 4(area of triangle)
Find the area of the triangle
A = 0.5(6)(5.2)
A =3(5.2)
A = 15.6 square inches
TSA = 4(15.6)
TSA = 62.4 square inches
Hence the amount of wrapping paper he uses is 62.4 square inches

Solve for x in the literal equation −5 = xy + z.
Answer: x = -5 -z/y or x= -5/y - z/y
Step-by-step explanation:
-5 = xy + z -- then you need to isolate the x, so subtract z from both sides
-5-z = xy -- then divide both sides by y
x= -5-z/y
Any help with this would be great, I'm not the best at these, and I'm behind from being sick and need to catch up.
Answer:
Step-by-step explanation:
Let say the following:
p = number of points
We know that they scored the same number of points in Game 1 and Game 2.
But in Game 3, they scored 6 points less than Game 1 and Game 2.
Therefore,
Game 1 = p
Game 2 = p
Game 3 = p - 6
To find the average you use the following formula:
Number of points / number of games = average
Basically,
(Game 1 + Game 2 + Game 3 ) / 3 = 63
So substitute the equations we made earlier and you get:
[tex]\frac{Game 1 + Game 2 + Game 3}{3} = 63\\\frac{p + p + (p - 6)}{3} = 63[/tex]
After this you just want to solve for "p"
Multiply both sides by 3 to get rid of the fraction:
p + p + (p - 6) = 63 x 3 = 189
3p - 6 = 189
Add 6 to both sides.
3p = 189 + 6 = 195
Divide both sides by 3
p = 195/3 = 65
So now we know p = 65 points. Substitute this back into our equations for each game:
Game 1 = p , Game 1 = 65 points
Game 2 = p , Game 2 = 65 points
Game 3 = p - 6 , Game 3 = 65 - 6 = 59 points

Carol gets paid $10 per hour to work as a lifeguard. This weekend, she worked on both Saturday and Sunday. She made a total of $80. Carol worked for 5 hours on Saturday. a For how many hours did she work on Sunday? Let x = hours spent working on Sunday. Choose the equation that represents this problem.
Answer:D
Step-by-step explanation: times the 10 by the amount of hours they did on saturday which is $50. Subtract $50 from the $80 the total and the answer is $30, divide 30 by 10 and thats 3 the amount of hours that they worked on sunday. 10(x+5)=80 x=3 (3+5)=8 10(8)=80
A circular flower bed is 17 m in diameter and has a circular sidewalk around it that is 3 m wide. Find the area of the sidewalk in square meters. Use 3.14 for π.
Step-by-step explanation:
A-a
A=3.14x10x10
=314m^2
a=3.14x8.5x8.5
=226.865m^2
=314-226.865
=87.135m^2
The data in the table can be modeled using an exponential function.
x | -1 | 0 | 1 | 2 | 3 |
y | 4 | 6 | 9 | 13.5 | 20.25 |
Based on the table, which function represents the same relationship?
A.) f(x) = 6 x 1.5^x
B.) f(x) = 0.67^x
C.) f(x) = 4 x 1.5^x
D.) f(x) = 6 x 0.67^x
Answer:
A
Step-by-step explanation:
You can plug in the x and y coordinates of the points to check which one is right.
The easiest point to start with is (0, 6).
[tex]A) 6=6*1.5^0\\B) 6=0.67^0\\C) 6=4*1.5^0\\D) 6=6*0.67^0[/tex]
Any number raised to the power of 0 is 1, so we can replace all of the exponents with 1.
[tex]A) 6=6\\B) 6=1\\C) 6=4\\D) 6=6[/tex]
That means we can immediately rule out B and C, since 6 clearly does not equal 1 or 4.
But since we still don't have our answer, we can plug in another point. Once again, you want to start with low, easy numbers, so let's plug in (1, 9).
[tex]A) 9=6*1.5^1\\D) 9=6*0.67^1[/tex]
Any number raised to the power of 1 is the same number:
[tex]A) 9=6*1.5\\D) 9=6*0.67[/tex]
Now we can multiply out both sides:
[tex]A) 9=9\\D)9=4[/tex]
Once again, it becomes immediately clear that D does not work, and A is therefore the correct equation.
You have 3 number
1, 9, and a missing number
The mean of the numbers is 4
work out the missing number
Answer:
2
Step-by-step explanation:
The last number is 2
You calculate this by the only way the mean can be 4 is if the 3 numbers= up to 12. so 9 + 1=10 and if were looking for 12 we need 2 more so 2.
10 + 2=12
When dealing with mean you calculate the sum of all the number(check) then divided by the total of numbers so 3
12 divided by 3=4 and 4= your mean

. Mr. Donut wants to paint a donut on the wall of his restaurant. The diameter of the outside edge of the donut will be 22 inches. The area of the hole of the donut will be 78.5 square inches. How much area will need to be painted if only the donut needs to be painted? Use 3.14 for π.
Answer:
The area needed to be painted is approximately 301.44 square inches.
Step-by-step explanation:
The shape of a donut is represented by two concentrical circles, whose area is described by the following formula:
[tex]A =A_{g}-A_{s}[/tex] (Eq. 1)
Where:
[tex]A[/tex] - Total area of the donut, measured in squared inches.
[tex]A_{g}[/tex] - Area of the greater circle, measured in square inches.
[tex]A_{l}[/tex] - Area of the lesser circle, measured in square inches.
By using the definition of the area of the circle, we expand the equation above:
[tex]A = \frac{\pi}{4}\cdot D^{2}_{ext} - A_{s}[/tex] (Eq. 1b)
If we know that [tex]\pi = 3.14[/tex], [tex]D_{ext} = 22\,in[/tex] and [tex]A_{s} = 78.5\,in^{2}[/tex], the area needed to be painted is:
[tex]A = \frac{(3.14)\cdot (22\,in)^{2}}{4}-78.5\,in^{2}[/tex]
[tex]A \approx 301.44\,in^{2}[/tex]
The area needed to be painted is approximately 301.44 square inches.

Answer:
The total change in the stock market is [tex]69\frac{3}{4}[/tex]
Step-by-step explanation:
Given;
the stock market at the beginning of the day = 30 3/4 points
the stock market at the end of the day = 100 1/2 points
The total change in the stock market from the beginning of the day to the end of the day is given by;
100 1/2 points - 30 3/4 points
[tex]= (100 -30) + (\frac{1}{2} -\frac{3}{4} )\\\\= 70 + (-\frac{1}{4} )\\\\= 70 - \frac{1}{4}\\\\= 69\frac{3}{4}[/tex]
