Answers
Answer:
The answer is
[tex]( - \frac{19}{2} \: , \: 2)[/tex]Step-by-step explanation:
The midpoint M of two endpoints of a line segment can be found by using the formula
[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(-10,10) and (-9,6)
The midpoint is
[tex]M = ( \frac{ - 10 - 9}{2} , \: \frac{10 - 6}{2} ) \\ = ( - \frac{19}{2} \: , \: \frac{4}{2} )[/tex]We have the final answer as

Answer:
f(4) = 5
Step-by-step explanation:
f(4) means x=4
Using the function 4 >0 so using the lowest part
x+1 when x>0
4+1
5
f(4) = 5
Answer:
20. f(4) = 5
21. f(-6) = -6
22. f(0) = 0
23. f(-5) = -5
Step-by-step explanation:
The function is defined differently depending on the interval that x is in.
If x < -6, then f(x) = -2x^2 - 1. Definition A.
If -6 <= x <= 0, then f(x) = x. Definition B.
If x > 0, then f(x) = x + 1. Definition C.
For each value of the function you are asked to find in questions 20 through 23, the first thing to do is to see in which interval x is. Then you decide which function definition to use.
20. f(4)
4 is in the interval of Definition C.
f(x) = x + 1
f(4) = 4 + 1
f(4) = 5
21. f(-6)
-6 is in the interval of definition B.
f(x) = x
f(-6) = -6
22. f(0)
0 is in the interval of definition B.
f(x) = x
f(0) = 0
23. f(-5)
-5 is in the interval of definition B.
f(x) = x
f(-5) = -5
What is the slope of the line described by the equation below?
4x-y=3
A. 1/4
B. -1/4
C. -4
D. 4
Answers
Answer: 4
Step-by-step explanation: First convert the equation to y = mx + b form.
Start by subtract 4x from both sides to get -y = -4x + 3.
From here, divide both sides by -1 to get y = 4x - 3.
Now in y = mx + b form, the slope is the multiplier, or the m.
So here, 4 is the slope.
Answer:
(D) 4
Step-by-step explanation:
In order to find the slope you need to rearrange the equation so that y is alone on one side, so:
4x - y = 3
-y = -4x + 3
y = 4x - 3
The slope is the coefficient in front of x, so the slope is 4

Find the midpoint of the line segment joining the points R(-5,5) and S(4.6).
Answers
Hey there! I'm happy to help!
To find the x value of the midpoint, you add the x values and divide by 2.
-5+4=-1
-1/2=-1/2
For the y value, you add the y values and divide by 2.
5+6=11
11/2=5 1/2
So, the midpoint is (-1/2, 5 1/2).

What is the value of x? Graph f(x) and f^-1 (x) on the same coordinate
Answers
Answer:
Find the answers in the explanation
Step-by-step explanation:
The given function is
f(x)=475-15x
A.) To find f^-1 and explain what it represents in this situacions, let f(x) = y. That is,
Y = 475 - 15x
Interchange y and x and make y the subject of formula
X = 475 - 15y
-15y = x - 475
Y = 475/15 - x/15
Y = (475 - x) / 15
Therefore,
f^-1(x) = (475 - x) / 15
If the function depreciates the smartphone, then, the inverse function will appreciate it.
When will the deprecated value of smart phone be less than $100.00
Substitute 100 for f(x) and find x
100 = 475 - 15x
-15x = 100 - 475
-15x = - 375
X = 375/15
X = 25
Therefore, the deprecated value of smart phone be less than $100.00 in the next 26 months.
what does x represent in f^-1(x) =30?
X represent the number of months for the smartphone appreciations
What is the value of x?
Substitute the inverse function for 30 and make x the subject of formula in the equation
f^-1(x) = (475 - x) / 15
30 = (475 - x) / 15
Cross multiply
450 = 475 - x
X = 475 - 450
X = 25 months
Graph f(x) and f^-1 (x) on the same coordinate

Write scientific notation 1081
Answers
Answer:
1.08 x 10³
Step-by-step explanation:
Calculating scientific notation for a positive integer is simple, as it always follows this notation: a x 10b.
Follow the steps below to see how 1,080 is written in scientific notation.
Step 1
To find a, take the number and move a decimal place to the right one position.
Original Number: 1,080
New Number: 1.080
Step 2
Now, to find b, count how many places to the right of the decimal.
New Number: 1 . 0 8 0
Decimal Count: 1 2 3
There are 3 places to the right of the decimal place.
Step 3
Building upon what we know above, we can now reconstruct the number into scientific notation.
Remember, the notation is: a x 10b
a = 1.08 (Please notice any zeroes on the end have been removed)
b = 3
Now the whole thing:
1.08 x 10³
Step 4
Check your work:
10³ = 1,000 x 1.08 = 1,080

2x – 3y = 18
Solve for y.
Answers
Answer:
y= -6+2/3x
Step-by-step explanation:
2x-3y=18
Minus the 2x from both sides
-3y=18-2x
Then divide both sides by -1
-3y÷-1=18÷-1 -2x÷-1
Lastly divide both sides by 3
3y÷3= -18÷3+2x÷3
The equation 2x - 3y = 18 can be written as y = (2/3)x - 6 after arranging the terms and making subject y.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The equation is:
2x – 3y = 18
2x - 3y = 18
-3y = 18 - 2x
y = (2/3)x - 6
Thus, the equation 2x - 3y = 18 can be written as y = (2/3)x - 6 after arranging the terms and making the subject y.

Describe how to solve 2x + 36-4x -10 ) = 10 to a middle schooler. Show all the steps and tell
us how you can check if it is correct.
Answers
Answer:
First you would have to combine the numbers that are the same, so combine all the X's and the other numbers, with out a variable (without an X). The numbers with X are 2x and -4x, so you add them, you should have 2x (2+ (-4)= 2) your equation should look like this : 2x + 36 - 10= 10
Next you need to combine the other numbers, 36 and -10, add them, and you should get 26. Your problem should look like this 2x+26=10
Next you will need to subtract 26 from each side, what you do to one side of the equal sign you must do to the other. Your problem should look like this : 2x=-16
To find X you have to get X alone, so you have to divide how many x's there are, 2, so divide both sides by 2 (rembering that what you do to one side you must do to the other). So you should have x= -8
