I believe the answer must be 96x-160
Because we have to multiply 8x12 which is 96. and there is x next to it. so keep the x as it is.
and next to it is minus ( - ) sign so keep it as it is.
now we have to multiply 8x20 which is 160.
so if we write it together it will be:
so if we write it together it will be:96x - 160.

Clara and toby are telemarketers. yesterday, Clara reached 6 people in 12 calls, while Toby reached 7 people in 13 phone calls. If they continue at those rates, who will reach more peoples in 40 phone calls? How many more?
Step-by-step explanation:
Firstly we determine how many people clara will reach in 40 phone calls.
6 people=12 calls
X people=40 calls.
make X the subject of the formula.
X=(6×40)÷12=20
So clara will reach 20 people in 40 phone calls.
Now lets determine how many people Toby will reach in 40 phone calls.
7 people=13 calls
Y people=40 calls.
Therefore making Y the subject of the formula we have,
Y=(7×40)÷13=21 people.
So toby will reach more people in 40 calls

t/4+5=20 how would you solve this problem
Answer:
t = 60
t/4+5=20
Step 1:
multiply both sides of equation by 4 to separate t from the fraction t/4.
t + 20 = 80
Step 2:
Subtract 20 from both sides of the equation ( you have to put constant values on the same side)
t= 80 - 20

f(x) = 4x + 2 over 3
Answer: f^-1(x)=(3x-2)/4
Step-by-step explanation:
1. Change the x and y
y=(4x+2)/3 → x=(4y+2)/3
2. Swap sides (optional)
x=(4y+2)/3 → (4y+2)/3=x
3. Multiply the equation by 3 on both sides
(4y+2)/3=x → (3)*(4y+2)/3=x*(3)
4. Subtract 2 from both sides
(3)*(4y+2)/3=x*(3) → 4y=3x-2
5. Divide 4 from both sides
4y=3x-2 → y=(3x-2)/4
6 Substitute f^-1(x) for y
y=(3x-2)/4 → f^-1(3x-2)/4
The function f(x) is defined as f(x) = One-third(6)x. Which table of values could be used to graph g(x), a reflection of f(x) across the x-axis?
The table of values that could be used to graph g(x), a reflection of f(x) across the x-axis is table (c)
How to determine the table of values?From the question, we have the following equation that can be used in our computation:
f(x) = One-third(6)x
When this statement is represented as an equation, we have the following representation
f(x)= 1/3(6)ˣ
The transformation is given as
A reflection of f(x) across the x-axis
This means that
g(x) = -f(x)
So, we have
g(x) = -1/3(6)ˣ
What this means is that the values of f(x) are negated to get g(x)
The table that represents this is table (c)
Hence, the table of values is table (c)

A farmer purchased 480 meters of fencing, and will build a rectangular pen with it. To enclose the largest possible area, what should the
pen's length and width be? Model the pen's area with a function, and then find its maximum value.
To enclose the largest possible area, the pen's length should be__and width should be__.
The largest possible area will be 14400 meters², the pen's length should be 120 meters, and the width should be 120 meters.
What is the perimeter of the rectangle?The perimeter of a rectangle is defined as the addition of the lengths of the rectangle's four sides.
Let's assume that the length of the pen would be x.
We have been given the perimeter as 480 meters.
Let w be the width of the rectangle and l be the length of the rectangle
The perimeter of a rectangle = 2(l+w)
So, 480= 2(x + w)
240 = x + w
w = 240 - x
Length = x and width = (240 – x)
Area = x(240 - x) = 240x - x²
To get the maximum area, we equate the first derivative of the area to zero.
A = 240x - x²dA/dx = 240 - 2x = 0
2x = 240
x = 120
So, width = 240 – x = 240 – 120 = 120.
Maximum area = length × width
Maximum area = 120 × 120 = 14400 meters²
Thus, the pen should be 120 meters long and 120 meters wide, with a maximum possible area of 14400 meters².

Liam is setting up folding chairs for a meeting. If he arranges the chairs in 7 rows of the same length, he has 5 chairs left over. If he arranges the chairs in 5 rows of that same length, he has 17 left over. How many chairs does Liam have?
Answer: 47
Step-by-step explanation: Let's call the number of chairs Liam has x. We can set up the following equations to represent the problem:
7r = x - 5
5r = x - 17
Where r is the length of each row.
To solve for x, we can set the two equations equal to each other:
7r = x - 5
5r = x - 17
Then we can solve for x by combining like terms and solving for the value of x:
7r - 5r = x - 5 - x + 17
2r = 12
r = 6
We can substitute the value of r back into either of the original equations to solve for x:
7r = x - 5
7 * 6 = x - 5
x = 47
Therefore, Liam has 47 chairs.
