Alberto uses the steps below to solve the equation One-half x minus 3 equals 7. Step 1: One-half x minus 3 plus 3 equals 7 plus 3 Step 2: One-half x plus 0 equals 10 Step 3: One-half x equals 0 Step 4: 2 (one-half) x equals 2 (10) Step 5: 1 x equals 20 Step 6: x equals 20 Which justifies Step 6 of his work?
Answer:
Identity property of multiplication
Step-by-step explanation:
From step 5:
[tex] 1x = 20 [/tex]
Here, to solve for x so that the variable x stands alone, Alberto uses the identity property of multiplication, which justifies what he has in step 6.
Step 6:
[tex] x = 20 [/tex]
According to the identity property of multiplication, any value you multiply by 1 gives you that same value.
Therefore, 1x = 1 × x = x.
The variable x multiplied by 1 will give you x.

Physics students were modeling the height of a ball once it was dropped from the top of a 10 foot ladder. The
students found that the height, in feet, h, of the ball above the ground as a function of the number of seconds, t, since
it wasdropped was given by h(t) = 10 - 2t^2
1. Determine an appropriate domain for the given scenario. Record your domain in both interval and set builder
notation.
Interval:
Set-Builder:
Justify your reasoning for choosing the above boundaries on your domain using the context of the problem.
How would the domain for this function differ if we were looking at it outside of the context of this problem?
Answer:
Interval notation: [0, 2.236]
Set Builder notation: [tex]\{t\ |\ 0\le t\le 2.236\}[/tex]
Step-by-step explanation:
Given that:
Equation of height of the ball dropped from a height of 10 foot, as:
[tex]h(t) = 10 - 2t^2[/tex]
Where [tex]t[/tex] is the time since the ball was dropped.
To find:
The domain of the function in Interval and set builder notation.
Solution:
Domain of a function is defined as the set of valid input values that can be given to the function for which the function is defined.
Here, input is time.
We can not have negative values for time.
Therefore, starting value for time will be 0 seconds.
And the value of height can not be lesser than that of 0 ft.
[tex]0= 10 - 2t^2\\\Rightarrow 2t^2=10\\\Rightarrow t^2=5\\\Rightarrow t =2.236\ seconds[/tex]
Maximum value for time can be 2.236 seconds.
Therefore the domain is:
Interval notation: [0, 2.236]
Set Builder notation: [tex]\{t\ |\ 0\le t\le 2.236\}[/tex]

solve the system of equations by the addition method
5x + 2y = 6
4x - 3y = 14
Answer: x=2, y=-2
Step-by-step explanation:
1) I will find x first, so make the amount of Ys same
3(5x+2y=6)
2(4x-3y=14)
2) 15x+6y=18
8x-6y=28
3) combine them together so Ys are all cancelled and 23x=46
4) x=2
5) for solving y, you can just plug in the x to any of that 2 equations, then 4(2)-3y=14
6) 8-3y=14
7) -3y=6
8) y=-2

A retail store is open for 8 hours each day. During a 5-day period, the store had 960 shoppers. Assume that the store had the same number of shoppers each hour during the 5-day period.
The number of shoppers each day is _
, and the number of shoppers each hour is _
.
Answer: 192 shoppers each day and 24 shoppers each hour
Step-by-step explanation:
-Each day= number of shoopers/number of days=960/5
=192 shoppers each day
-each hour per day=number of shoppers per day/number of hours per day
=192/8
=24 shoppers per hour

II. Let f(x) = 9 – x , g(x) = x2 + x, and h(x) = x – 2. Compute the following:
9. H(g(x)) and h(g(f(x)))
Answer:
[tex]h(g(x))=x^2+x-2[/tex]
[tex]h(g(f(x))= x^2-19x+88[/tex]
Step-by-step explanation:
Composite Function
Suppose f(x) and g(x) are real functions, the composite function named [tex](f\circ g)(x)[/tex] is defined as:
[tex](f\circ g)(x)=f(g(x))[/tex]
The composite function can be found by substituting g into f.
We are given these functions:
[tex]f(x)=9-x[/tex]
[tex]g(x)=x^2+x[/tex]
[tex]h(x)=x-2[/tex]
Find:
a) h(g(x))
Substituting g into h:
[tex]h(g(x))=x^2+x-2[/tex]
b) h(g(f(x))
First we find g(f(x)):
[tex]g(f(x))=(9-x)^2+(9-x)[/tex]
Operating:
[tex]g(f(x))=81-18x+x^2+9-x[/tex]
Simplifying:
[tex]g(f(x))=90-19x+x^2[/tex]
Now find h(g(f(x)) replacing the above equation into h:
[tex]h(g(f(x))= 90-19x+x^2-2[/tex]
Simplifying and rearranging:
[tex]h(g(f(x))= 88-19x+x^2[/tex]
[tex]h(g(f(x))= x^2-19x+88[/tex]
Dalyn has been asked to consider the following functions:
f (x) = 6x² - 12x + 11
g (x) = 6(x - 1)² + k
Dalyn would like to find a value of a k such that both f(x) and g(x) model the same graph. Help Dalyn solve for the value of k so both functions will represent the same graph.
Answer:
In order that both functions to represents the same (one) graph then the value of k is 5
Step-by-step explanation:
The given functions are;
f(x) = 6·x² - 12·x + 11
g(x) = 6·(x - 1)² + k
Expanding the function g(x) gives;
6·(x - 1)² + k = 6 × (x² - 2·x + 1) + k = 6·x² - 12·x + 6 + k
∴ 6·(x - 1)² + k = 6·x² - 12·x + 6 + k
Comparing with the function for f(x), we have;
f(x) = 6·x² - 12·x + 11
g(x) = 6·(x - 1)² + k = 6·x² - 12·x + 6 + k
The difference between the two functions is the constant term, which are;
Constant term for f(x) = 11
Constant term for g(x) = 6 + k
For the two terms to describe exactly the same graph, the constant term should also be equal
We will then have, 11 = 6 + k
∴ k = 11 - 6 = 5
k = 5
For both functions to represent the same graph the value of k = 5.

Step-by-step explanation:
Ok! So you want to find slope! First, you will need two points which you already have. Next, you will want to plot those two points on a graph. Once, you have that you can draw a straight line between the two points and until the end of the graph. After that, you want to find the rise/run or rise over run. Rise meaning up or down and run meaning left or right. Sometimes your problem will want you to keep the rise/run format and sometimes your problem will ask for a who number in which case you will divide your rise/run (rise ÷ run). How to find the rise over run you ask, simple! Draw a line-up or down from your first (or second) point whichever works, until you reach the y-value of your second (or first) point one your two points are connected, count the rise (up or down) and then the run (left or right). If your run goes left its a negative, right a positive. If your rise goes up its a positive, down a negative.
Boom! You know how to find slope!
Hope this Helps! :)

ben and winston ade both selling cookie dough for a fundraiser. Although ben has already sold 10tubs, Winston hasnt sold any yet. If ben starts selling
8tubs per day and Winston begins selling 9tubs per day, they will eventually sell the same amount of cookie dough. how many days will that take
? Plzzz help
Answer:
Step-by-step explanation:
On the first day, Ben (B) starts with 10 tubs and Winston (W) starts with 0 tubs.
After the first day, Ben sells 8 tubs per day while Winston sells 9 tubs per day.
Therefore we can write the following equation: (Where d = number of days)
B = 10 + 8d
W = 0 + 9d = 9d
We are told that eventually they will sell the same amount which means
B = W
This means we can say,
10 + 8d = 9d
If we subtract 8d from both sides we get
10 = d
Therefore it will take 10 days for them to sell the same amount of cookie dough.
Answer: 10 days
10 + 8 x 10 = 90
9 x 10 = 90.
It will take 10 days for Ben and Winston to sell the same amount of cookie dough.
Hope this helps you!

Find the volume of a rectangle box given the length of x, width of (x-2) and height of (3x+5)
Answer:
3x^3 − x^2 − 10x
Step-by-step explanation:
V= l*w*h
V= x * (x-2) * (3x+5)
V= (x(x−2)) (3x+5)
= (x(x−2)) (3x) + (x(x−2)) (5)
= 3x^3 − 6x^2 + 5x^2 − 10x
=3x^3 − x^2 − 10x
