Answer:
[tex]7x^{2}-4x[/tex]
Step-by-step explanation:
Area of a rectangle is expressed as Length * Width
Given the length/height = x
width = 7x-4
Area of the rectangle = [tex]x(7x-4)[/tex]
On opening the bracket;
Area of the rectangle = [tex]7x^{2}-4x[/tex]

l-9l 2. l64l 3. l-22l
Answer:
see below
Step-by-step explanation:
The absolute value means take the non negative value
l-9l = 9
l64l =64
l-22l=22
Answer:
1. 9 2. 64 3. 22
Step-by-step explanation:
The obsolute value is how far away the number is from zero
For example:
I-94I is 94
but
-I94I is -94
if the negative is outside the equation then its a negative

The table shows Peter's net worth statement. Assets are shown as positive numbers, and liabilities are shown as negative numbers. The value of Peter's house is not given. Peter's net worth is $101,800. Based on the information in the table, what is the current value of Peter's house?
Answer:
Value of House = $98000
Step-by-step explanation:
The sum of all of the assets and liabilities + value of the house = $101,800
Value of House + $900 - $3400 + $16900 - $16300 + $4500 + $1200 = $101,800
=> Value of House + $3800 = $101,800
=> Value of House = $101,800 - $3800
=> Value of House = $98000
The current value of Peter's house will be $98000.
A table is given which shows Peter's net worth and assets are shown as positive numbers, and liabilities are shown as negative numbers.
We have to find out the current value of Peter's house if , Peter's net worth is $101,800.
What will be the resulting value ; 35 - 10 - 5 + 10 = ?
The resulting value will be 30.
As per the question ;
The sum of all of the assets and liabilities plus value of the house is equal to $101,800.
Assume value of house = x
⇒ x + $900 - $3400 + $16900 - $16300 + $4500 + $1200 = $101,800
⇒ x + $3800 = $101,800
⇒ x = $101,800 - $3800
⇒ x = $98000
Thus , the current value of Peter's house will be $98000.

A jacket usually sells for $57.00. If the jacket is 40% off, and sales tax is 5%, what is the total price of the jacket, including tax?
Answer: $35.91
Step-by-step explanation:
Since the jacket is 40% off, we multiply the original price by 60% to get the price remaining. ($57 x 0.6 = $34.20)
Then, we multiply the new price by 105% (includes the 5% sales tax) to get the total price. ($34.20 x 1.05 = $35.91)
For what value of b, would the equation 34(12x−9)+b4=5−3(2−3x) have infinitely many solutions? Enter the numerical value only

The given expression is a linear function and has a unique solution.
Given,
For what value of b, would the equation 3/4(12x−9)+b/4=5−3(2−3x) have infinitely many solutions?
Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in set of y. x is the independent variable while Y is the dependent variable.
Here,
3/4(12x−9)+b/4=5−3(2−3x)
12x - 27 / 4 + b / 4 = 5 - 6 + 9x
12x - 9x = -1 + 27/4 - b / 4
3x = 23 - b / 4
Here the expression is a linear function of x, so the expression has a unique solution not infinitely many solutions.
Thus, the given expression is a linear function and has a unique solution.

Write a function with no horizontal shift for the sinusoid shown.
We have been given graph of a sinusoidal function. We are asked to write function formula for our given graph.
We know that [tex]\sin(0)=0[/tex] and [tex]\cos(0)=1[/tex]. We can see that our given function is starting at origin, so our graph is sine function.
We know that general form of sine is [tex]y=A\sin[B(x-c)]+D[/tex], where,
A = Amplitude,
Period: [tex]\frac{2\pi}{B}[/tex]
C = Horizontal shift,
D = Vertical shift.
We have been given that function has no horizontal shift, so the value of C is 0.
We can also see that midline of our function is x-axis, so there is no vertical shift as well that is [tex]D=0[/tex].
We can see that function goes up to 1 from midline and goes down to [tex]-1[/tex] from midline, so amplitude of function is 1 that is [tex]A=1[/tex].
We can see that period of our given function is [tex]4\pi[/tex] because it completes one cycle from [tex]-\pi[/tex] to [tex]3\pi[/tex]
[tex]4\pi=\frac{2\pi}{B}[/tex]
[tex]B=\frac{2\pi}{4\pi}=\frac{1}{2}[/tex]
[tex]y=\sin(\frac{1}{2}x)[/tex]
We can see that our function is reflected about x-axis, so our function will be [tex]y=-f(x)[/tex].
[tex]y=-\sin(\frac{1}{2}x)[/tex]
Therefore, our required function is [tex]y=-\sin(\frac{1}{2}x)[/tex].
A used car dealer prices her cars so that she makes a minimum profit of 15% on each car sold. If she acquired a car for $4,500, which inequality can be used to determine the acceptable selling prices, p, of that car? 1.15 p less-than-or-equal-to 4,500 1.15 p greater-than-or-equal-to 4,500 p less-than-or-equal-to 1.15 (4,500) p greater-than-or-equal-to 1.15 (4,500)
Answer:
[tex]p\geq 1.15(4,500)[/tex]
Step-by-step explanation:
If she makes a minimum profit, we need to use the symbol [tex]\geq[/tex], which indicates minimum quality.
Let's call [tex]p[/tex] profit, so the inequality which represent this problem would be
[tex]p\geq 1.15(4,500)[/tex]
The price of the car is multiplied by 1.15, because she must add her profit comission which is 0.15 or 15%.
Therefore, the right answer is the last choice.

2) MZBAC -
3) ABAC and ABOC are isosceles.
4) The area of ABAC is twice the area
of ABOC.
m_BOC
Answer:
It would be number 2. measure of angle BAC is equal to half the measure of angle BOC.
Step-by-step explanation:
This is because of inscribed angles.
In the diagram below of circle O, OB and OC are radii, and chords AB, BC, and AC are drawn. The correct statement is B. m < BAC = 1/2 m < BOC.
How to explain the circle?From the information given, (a + b) + (a + c) + (b + c) = 180°
2a + 2b + 2c = 180°
2a + 2b = 180° - 2c
2(a + b) = 180° - 2c
Therefore, m < BAC = 1/2 m < BOC.
In conclusion, the correct option is B.

Yesterday, two friends went into a bank to open savings accounts. Megan started by putting $80 in her account, and she will deposit an additional $15 each week. Noah made no initial deposit, but he will add $25 more each week. In a few weeks, the friends will have the same account balance.
Answer:
8 weeks
Step-by-step explanation:
We are to find the number of weeks that they will have the same account balance.
Let the number of weeks be x.
Megan started by putting $80 in her account, and she will deposit an additional $15 each week. This means after x weeks, she will have:
80 + 15x
Noah made no initial deposit, but he will add $25 more each week. After x weeks, he will have:
25x
To find the number of weeks for their amounts to be the same, we equate their amounts to one another:
80 + 15x = 25x
Collexting like terms and solving for x:
80 = 25x - 15x
80 = 10x
=> x = 80 / 10 = 8 weeks
After 8 weeks, the money in their accounts will be the same.

You pick a card at random. Without putting the first card back, you pick a second card at random.
What is the probability of picking a 3 and then picking a 3?
Simplify your answer and write it as a fraction or whole number.
Answer:
You have three card : 3, 4, 5 and 6.
You first pick one card randomly, the probability of picking a 3 is:
P = 1/4
You then pick a second card without putting the first card back, the probability of picking a 3 is:
P = 1/3
=> The probability of picking a 3 and then picking a 3:
P = (1/4) x (1/3) = 1/12
