Answer:
2nd graph in yellow
Step-by-step explanation:
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:

and
y=x+2
Plotting these two functions on the X-Y plane, the common point of these curves is the common value which can satisfy both the equations simultaneously, and thus, being the solution to the considered system of equations.
Thus, the solutions are those two points that are intersections of those two curves.
The kite shown below is translated 8 units to the right and 1 unit up.
Which property will remain the same?
A.
the coordinates of the x-intercept
B.
the coordinates of the vertices
C.
the perimeter of the kite
D.
the angle between the top vertex and the origin
Answer:
C. The perimeter of the kiteStep-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.

a skydiver jumps out from the plane at 10,000 feet above the ground. the skydiver decends at a rate of 175 feet per seconds. how high in the air is the skydiver when he opens his parachute after 25 seconds?
Answer:
5625 feet
I hope it's helps you
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
sandra calculated the trend line for a scatter plot to b y=3x+1-. What is the predicted value of x=40?
a. 80
b. 125
c. 130
d. 53
The predicted value of the scatter plot at x=40, according to Sandra's trend line prediction will be 130.
What is a scatter plot?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.

Plz help ASAP I’ll give brainliest I’ll be so grateful but don’t copy off website:)
Answer:
You can find X in an equation by doing the opposite operation from both sides. For example, let"s do 5x=25. Since there is multiplication, we can use division to isolate the variable. You would divide both sides by the coifeiccent to get x=5.

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.

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:
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.
Determine whether a linear, quadratic, or exponential function is the best model for the data in the table.
Answer:
exponential function and common ratios

I learned how to find the area of a triangle with 2 numbers (0.5*b*h), but how do you find the area with 4 numbers?
Answer:
area =12
Step-by-step explanation: you don't need to use all 4 numbers just used the base which is 8 then times it with 3 which gives you 24 then divided it by 2 which gives you 12.
Answer:
Area=12
Step-by-step explanation:
You take the height which is 3 and multiply it by the base which is 8. Then you get 24 and divide it by 2 which gives you 12.

Which of the following allows you to compare the frequency of intervals, but not the frequency of exact values?
A.a dot plot
B.a stem-and-leaf plot
C.a histogram
D.a circle graph
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.
What is a Histogram?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

Skye made a deposit of $625 into an account that earns 4% simple interest for 6 years. How much did Skye earn in interest at the end of 6 years?
Answer:
She will earn 150$
Step-by-step explanation:
4% = 0.04
0.04 x $625 = 25
Now we divide 25 by the number of years, which is 6.
6 x 25 = 150$
Therefore, Skye earns 150$ from interest over the course of 6 years.
You spin the spinner, flip a coin, then spin the spinner again. Find the probability of the compound event. Write your answer as a fraction or percent rounded to the nearest tenth.
The probability of spinning an odd number, not flipping heads, then not spinning a 6 is
__
Using it's concept, it is found that the probability of spinning an odd number, not flipping heads, then not spinning a 6 is:
[tex]p = \frac{20}{81} = 24.69\%[/tex]
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem:
There are 5 odd numbers in the spinner, out of 9, hence the probability of spinner an odd number is 5/9.The coin is fair, hence the probability of flipping tails = not heads is of 1/2.Out of the 9 numbers in the spinner, only one is six, hence the probability of not spinning a 6 is of 8/9.Then, the probability of the compound event is:
[tex]p = \frac{5}{9} \times \frac{1}{2} \times \frac{8}{9} = \frac{20}{81} = 24.69\%[/tex]
