Answer:
f ⁻¹(x) = [tex]\sqrt{x + 3}[/tex]Step-by-step explanation:
Find the inverse of f(x) = x² - 3
Substitute x with y and f(x) with x and solve for y:
x = y² - 3y² = x + 3[tex]\sqrt{y^2}[/tex] = [tex]\sqrt{x + 3}[/tex]y = [tex]\sqrt{x + 3}[/tex]Replace y with f⁻¹(x):
f ⁻¹(x) = [tex]\sqrt{x + 3}[/tex]Step-by-step explanation:

what conclusions can you give why some students decided not to go to school?
Step-by-step explanation:
There are a number of reasons why some students decide not to go to school. Some of them may be associated with family and psychological problems such as anxiety and depression, which should be investigated by trained professionals at the school if there is any suspicion of these symptoms.
There is also the possibility that students who have decided not to go to school have been victims of bullying and aggression at school, which causes fear of retaliation and psychological trauma that negatively impact the person's life.
It is important that schools provide psychological support and an active policy that combats bullying and is pro-integration of students and diversity.

C. [tex]x=\frac{3}{2} , y=\frac{1}{2}[/tex]
Step-by-step explanation:
Both of the equations would equal to one another since they're both solving for "y".
Steps: Plug in x into one of the equation:
[tex]-x+2=3x-4[/tex] [tex]y=3(\frac{3}{2} )-4[/tex]
[tex]-3x+4[/tex] [tex]-3x+4[/tex] [tex]=\frac{9}{2} -4[/tex]
------------------------ [tex]=4.5-4[/tex]
[tex]-4x+6=0[/tex] [tex]y=0.5 or \frac{1}{2}[/tex]
[tex]-6[/tex] [tex]-6[/tex]
------------------
[tex]\frac{-4x}{-4} =\frac{-6}{-4}[/tex]
[tex]x=\frac{3}{2}[/tex]
[tex]x=\frac{3}{2} , y=\frac{1}{2}[/tex]
8 cubed as a single power of 2
Answer:
[tex]2^{9}[/tex]
Step-by-step explanation:
Using the rule of exponents
[tex](a^m)^{n}[/tex] = [tex]a^{mn}[/tex]
note that 8 = 2³ and so
8³ = (2³ )³ = [tex]2^{3(3)}[/tex] = [tex]2^{9}[/tex]
9. A group of 14 friends went to a basketball game and paid a total of $70 for their admission tickets. They received a discount of $2 off the original price (p) of each ticket. What is the value of p?
the answer is $7
Step-by-step explanation:
70 divided by 14 is 5.
cost would be $5 per person before discount of $2
$5 plus $2 equal $7
p= $7
3. What are the factors in the expression 4(5 + x)?
Answer:
Step-by-step explanation:
The factors are the parts that are being multiplied together.
4 and (5+x) are the two that are being multiplied and also the expression you get when you factor the distributed expression.
So the factors of 4(5+x) are:
4 and (5+x)

Answer:
5x + 3y = 95
8x + 6y = 170
x = 10 ; y = 15
Step-by-step explanation:
Let :
x = pack of juice boxes
y = pack of water bottles
Pack of juice box = $5
Pack of water bottles = $3
Amount of money spent :
5x + 3y = $95
Number of drinks purchased :
8x + 6y = 170
Using both equations ;
5x + 3y = 95 - - - (1)
8x + 6y = 170 - - - (2)
Multiply (1) by 6 and (2) by 3
30x + 18y = 570
24x + 18y = 510
Subtract :
6x = 60
x = 60 / 6
x = 10
Put x = 10 in (1)
5(10) + 3y = 95
50 + 3y = 95
3y = 95 - 50
3y = 45
y = 45 / 3
y = 15
x = 10 ; y = 15

6.85 x 10^8 = 685,000,000
can any of you guys help out by showing work on how this is the answer
Answer:
Step-by-step explanation:
10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 = 100000000
100000000 x 6.85 = 685,000,000
Answer:
scientific notation. I did this a few moths ago.
Step-by-step explanation:
since it is 10^8 you're going to move your decimal as far the right as you can which then changes it to 685. x 10^6. After that you add 6 zeros (from the 10^6) and change it from a decimal to a comma to get 658,000,000... i hope this helps

PLEASE HELP!!! Find the slope of the line that passes through the points (-1,7) and (0,-3).
Answer:
-10
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-3-7)/(0-(-1))
m=-10/(0+1)
m=-10/1
m=-10
Answer:
The slope is -10.
Step-by-step explanation:
Goal
Find the value of m/Find the slope.Given
Two coordinate points which are (-1,7) and (0,-3).Step 1
Use the slope formula which is rise over run also known as changes of y over changes of x.[tex] \large \boxed{m = \frac{y_2-y_1}{x_2-x_1} }[/tex]
From the given coordinate points, substitute the values in the formula.
[tex]m = \frac{7 - ( - 3)}{ - 1 - 0} \\ m = \frac{7 + 3}{ - 1} \longrightarrow \frac{10}{ -1} \\ m = - 10[/tex]
Therefore, the value of m or slope is -10.

About how many inches does a
20-inch diameter tir roll in one
turn? (Use 3.14 for it.)
Step-by-step explanation:
diameter = 20 inches
radius = diameter ÷ 2
radius = 20 ÷ 2
= 10 inches
circumference = 2π × radius
= 2 × 3.14 × 10
= 62.8 inches
