Answer:
The numbers are 8 and 6
Step-by-step explanation:
Let x and y be the two numbers
x+y = 14
x-y = 2
Add the two equations together
x+y = 14
x-y = 2
--------------
2x +0y = 16
Divide by 2
2x/2 = 16/2
x = 8
Now find y
x+y = 14
8+y =14
Subtract 8 from each side
8+y-8 =14-8
y =6
The numbers are 8 and 6
Answer:
8 and 6

Answer:
4.5 cm
Step-by-step explanation:
The volume of a sphere is given by
V = 4/3 pi r^3
121.5 pi = 4/3 pi r^3
Divide each side by pi
121.5 = 4/3 r^3
Multiply each side by 3/4
3/4 *121.5 = 3/4 * 4/3 r^3
91.125 = r^3
Take the cube root of each side
(91.125)^ (1/3) = r^3 ^(1/3)
4.5 = r
Can I get help? And plzzzz give steps to how you found your answer.

Part B: Describe how you can make the line of the best fit. write the approximate slope and y-intercept of the line of best fit. Show your work, including the points that you use to calculate the slope and y-intercept.
(please explain how you got the slope and y-intercept with the numbers from the question if you would like brainliest)
Answer: We are using a line regression tool to solve the parameters asked in the problem. We can use online tools or that of Excel. According to the tool, the best fit values are
Slope0.3848 ± 0.03956
Y-intercept0.6053 ± 0.6370
X-intercept-1.573
1/Slope2.598
Step-by-step explanation: Best fit lines make sure that the standard deviation at each point is minimum from the best fit line.

1. f(x)+g(x) . Solve it algebraically and then graph the result on the same graph above. (Creating a table for each function might be helpful as well)
2. Is there a way of determining the graph of f(x)+g(x) without solving it algebraically? Explain your thinking below. If you do not notice a pattern then try the combination f(x)=x+2 and g(x)=1.
Answer:
73
Step-by-step explanation:
1. Select all the equations that have 2 solutions.
A. (x + 3)2 = 9
B. (x – 5)2 = -5
C.)(x + 2)2 – 6= 0
D. (x – 9)2 + 25 = 0
E. (x + 10)2 = 1

$18.75 to $18.60 identify the percent of change as an increase or decrease . then find the percent of change round to the nearest tenth of a percent , if necessary
Answer:
0.8%
Step-by-step explanation:
There is a decrease in percentage by 0.8%.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
The given decimal numbers are $18.75 and $18.60.
We know that, percentage change = (Original price-New price)/Original price ×100
= (18.75-18.60)/18.75 ×100
= 0.15/18.75 ×100
= 0.008×100
= 0.8%
Therefore, there is a decrease in percentage by 0.8%.
