Answer: A is yes. B is no, C is yes

Step-by-step explanation: The reason A is yes, is because the terms are 27b, 12b and 4 because they are separated. The reason B is no, is because the like terms are 27b and 12b because their variables are alike. The reason C is yes, is because 27b+12b=39b+4 is an équation simplified.

Answer:

Answer:

B

Step-by-step explanation:

I am not sure what your teacher wants but I guess you can say the following:

at n = 1, the cost is 4 dollars.

at n = 2, the cost is 8 dollars.

This trend is the same where the cost increases by 4 as n increases by 1. This means the C = 4n. We can check this by plugging values into the equation.

For the first row, C = 4, n = 1, and so the equation satisfies it. For the second row in the table, C = 8, n = 2, and so the equation works again. The other data points also agree using the equation.    

The type of graph that allows you to compare the frequency of intervals, but not the frequency of exact values is a stem-and-leaf plot.

An histogram is a graphical representation of a data distribution, which uses bars or bins to represent the frequency of the data distribution that are in intervals.

Similarly, in dot plot the total number of dots tells us the total number of observations of the values of that thing we did.

The Stem and leaf plot is to show the data distribution while retaining its uniqueness which shows the raw values by retaining the original data,

The type of graph that allows you to compare the frequency of intervals, but not the frequency of exact values is a stem-and-leaf plot.

Therefore, the graph used to show data in intervals is: B.a stem-and-leaf plot

Answer:

c ???

Step-by-step explanation:

The predicted value of the scatter plot at x=40, according to Sandra's trend line prediction will be 130.

A scatter plot is a form of plot or mathematical diagram that displays values for two variables for a collection of data using Cartesian coordinates. One more variable can be presented if the points are programmed.

To get the predicted value to the scatter plot at x=40, substitute the value of x as 40 in the given function of the trend line. Therefore, the value will be,

[tex]y = 3x+10\\\\y = 3(40)+10\\\\y=130[/tex]

Hence, the predicted value of the scatter plot at x=40, according to Sandra's trend line prediction will be 130.

Answer:

244140625 or 5^12

Step-by-step explanation:

When it comes to multiplication, you add exponents IF the base (the 5 at the bottom is called base) is the same answer. for example: 1^16 x 1^9, since the exponents are the same you just add the exponents (16 & 9) which is 25 or 1^25

Dividing is the same as multiplying except your subtracting with the examples, adding and subtracting is simplifying and solving, for example

14^2 + 13^3

          14 * 14 = 196

                   13*13*13 =2,197

          196+2,197 = 2,393

Same thing for subtraction

13^3 - 14^2

2,197 - 196 = 2,001

The system of equations needed to solve the given equations is . Thus, the correct graph is the top-right graph. Its plotted below.

How to find the system of equations needed to solve an equation?

An equation usually consists of equality of two mathematical expressions. Let it be

�

A=B . If we take them to be equal to third variable, then:

A=B=C type of equation is obtained.

We can then take it as system of two equations as:

A=C

B=C

Solution to this system will give us the solution to the considered equation

What is a solution to a system of equations?

For a solution to be solution to a system, it must satisfy all the equations of that system, and as all points satisfying an equation are in their graphs.

For the given case, we are given that:

Thus, the solutions are those two points that are intersections of those two curves.

Answer:

D.

Step-by-step explanation:

As you can see, there is a total of 8 slices, and 5 are shaded. So, you know that it is 5/8. As you can also see, there is 5 of these. So, you would have 5/8 5 times, or:

Answer:

5625 feets

Step-by-step explanation:

Rate(feet/seconds) = height(feets)/time(seconds)

175 = x/25

x = 4375

After the skydiver opens his parachute the height reduces

Initial height – reduced height

10000 – 4375

= 5625 feets

Answer:

b

Step-by-step explanation:

Answer:

Function 1: None of the Above

Function 2: Quadratic

Function 3: Linear

Step-by-step explanation:

Function 1: It isn't linear because the y-axis doesn't go up or down at a constant rate, it isn't quadratic because it doesn't have a vertex, and it isn't exponential because it doesn't continue going up.

Function 2: It has a vertex-(6,32)

Function 3: The y-axis goes up at a constant rate of 6.

Step-by-step explanation:

Answer A is not correct because if the kite moves both right and up, the x and y coordinates will change

Answer B is the same as answer A. The kite moved so the coordinates will change.

Answer D is also the same. If the kite moves both on the x and y axis, any angle and distance will change.

Answer C is correct. Since C does not rely on the coordinates, it will always be the same. The position of a shape does not change it´s perimeter.

Answer:

40.56 in.

Step-by-step explanation:

8 × 3.14 × 1/2 = 12.56 (perimeter for the half circle)

12.56 + 10 + 8 + 10 = 40.56

Answer:

Perimeter = 40.56 inches

Explanation:

The perimeter of a shape is all side lengths added up, so, we know there are sides with the lengths 10 inches, 10 inches, 8 inches, and a semicircle.

To find the perimeter of a semicircle, the formula is

C = πd/2, circumference equals pi times diameter divided by 2 OR C = πr, circumference equals pi times radius.

The diameter is 8, so, filling out the formula, it's

C = 3.14 x 8 /2

C = 25.13/2

C = 12.56

So, adding all the sides up, it's 10 in. + 10 in. + 8 in. + 12.56 in.

Therefore, the answer/perimeter/circumference is 40.56 inches.
