Answer:
(x²+3x-88) square units
Step-by-step explanation:
Area of a rectangle = Length × Width
Given
length of a rectangle is (x-8)units
Its width is (x+11) units.
Required
Expression for the area of the rectangle
Substituting the given function into the formula.
Area of the rectangle = (x-8)(x+11)
Area of the rectangle = x(x)+11x-8x-88
Area of the rectangle = x²+3x-88
Hence the expression that represents the area of the rectangle is x²+3x-88 units²

What is an Algebraic expression?An algebraic expression can be obtained by doing mathematical operations on the variable and constant terms.
The variable part of an algebraic expression can never be added or subtracted from the constant part.
The given function is as below,
f(x) = 3x² - x + 5
The value of the function at x = -3 and 4 can be found by substituting the respective values of x in the expression of f(x) as follows,
f(-3) = 3 × (-3)² - (-3) + 5
= 25
And, f(4) = 3 × (4)² - 4 + 5
= 49
Then, 2f(-3) - f(4) = 2 × 25 - 49
= 1
Hence, the given expression can be evaluated as 2f(-3) - f(4) = 1.

Answer:
f(-6) = -2
Step-by-step explanation:
plug in k value (-6)
f(-6) = -6/2 + 1
theres two ways to solve for this
one way:
convert the whole number 1 to an improper fraction
f(-6) = -6/2 + 2/2
combine like terms
f(-6) = -4/2
divide -4 by 2
f(-6) = -2
second way:
divide -6 by 2
f(-6) = -3 + 1
combine like terms
f(-6) = -2
either way you get the same answer

Given: DEFG is a parallelogram.
Parallelogram D E F G with diagonal D F. Angle G D F is labeled 1, angle F D E is labeled 2, angle E F D is labeled 3, and angle D F G is labeled 4.
Prove: DE¯¯¯¯¯≅GF¯¯¯¯¯ and DG¯¯¯¯¯¯≅EF¯¯¯¯¯ .
Opposite sides of a parallelogram are parallel, so Response area because they are alternate interior angles. By the reflexive property of congruence, DF¯¯¯¯¯≅DF¯¯¯¯¯ . Therefore, △DGF≅△FED by the Response area . That means DE¯¯¯¯¯≅GF¯¯¯¯¯ and DG¯¯¯¯¯¯≅EF¯¯¯¯¯ by Response area.
Answer:
[tex]\overline{DE} \cong \overline{GF}[/tex] and [tex]\overline{DG} \cong \overline{EF}[/tex] by CPCTC
Step-by-step explanation:
The given information are;
The shape of the given polygon DEFG = Parallelogram with diagonal DF
Therefore, we have;
Response area
[tex]\overline{DE} \left | \right | \overline{GF}[/tex] and [tex]\overline{DG} \left | \right | \overline{EF}[/tex] (Opposite sides of a parallelogram are parallel)
∠GFD ≅ ∠EFD (Alternate interior angles)
∠DFG ≅ ∠FDE (Alternate interior angles)
[tex]\overline{DF} \cong \overline{DF}[/tex] (By the reflexive property of congruence)
Therefore
ΔDGF ≅ ΔFED (Angle-Side-Angle (ASA) condition of congruency)
Which gives;
[tex]\overline{DE} \cong \overline{GF}[/tex] and [tex]\overline{DG} \cong \overline{EF}[/tex] (Congruent Parts of Congruent Triangles are Congruent (CPCTC).
Emily created the net worth statement shown.

Based on the information in the table, what is Emily’s net worth?
A.$107,550
B.$87,025
C.$20,525
D.$128,075
Answer:
D hopefully this have helped you !
Step-by-step explanation:
The solution is Option B.
The total net-worth of Emily is given by the equation A = $ 87,025
What is Net Worth?An individual's net worth is the difference between their assets (both long-term and short-term) and their liabilities (long-term and short-term).
The net worth of a company is equivalent to its equity, which refers to the net assets owned by the stockholders after paying off all debts.
So , Net Worth = Assets - Liabilities
Given data ,
Let the net worth of Emily be represented as A
Now , the equation will be
The assets of Emily are = Checking account $750 + Automobile (current value) $8,950 + House (current value) $92,500 + Savings account $1,350 + Investments $4,000
The total assets of Emily = $107,550
And , the liabilities of Emily are = Credit card debt $3,800 + Student loans $15,750 + Personal loans $975 + Total Liabilities $20,525
Now , the total liabilities of Emily = $20,525
So , the net worth = Assets - Liabilities
Substituting the values in the equation , we get
Net worth of Emily A = $107,550 - $20,525
On simplifying the equation , we get
Net worth of Emily A = $ 87,025
Hence , the net worth of Emily is $ 87,025

what graph passes the vertical line test?
Answer:
The fourth image, or D.
Why?
If you had a ruler and placed it on the grid vertically and moved the ruler left to right, pictures A, B, and C, all have two points that lay on the same X point.
Picture D is the only one that has no points that lay on the same X point, thus making it the right answer.
Thank you for reading into this.
(Hope this helps you! ^^)
The last graph (shown below) passes the vertical line test
The vertical line test is used to ascertain whether or not a graph represent a function.
Vertical lines are drawn across the graph. If the vertical line intersects more than one point on the graph, then the graph does not represent a function.
If a vertical lines are drawn across all the graphs shown, only the last graph indicated below will pass the vertical line test.
Therefore, the graph shown below represents a function because it obeys the vertical line test

Micah is 4 more than twice Angela’s age. The sum of their ages is 40. Set up the problem, Write an equation, Solve the equation, Determine how old Micah and Angela are.
Answer:
Angela is 12 and Micah is 28.
Step-by-step explanation:
So, the problem tells us that Micah is four more than twice Angel's age, and the sum of both their ages is 40. So, if we use a to stand for Angela's age and m to stand for Micah's age, we can safely assume our equation will look like this:
(a × 2) + 4 = m. And once that is figured out, we use a + m = 40.
For right now, we can start just randomly entering in numbers for a. Let's try 10, for example.
(10 × 2) + 4 = 24.
But does 10 + 24 = 40? No, it equals 34. So we go higher.
(12 × 2) + 4 = 28.
Does 12 + 28 = 40? Yes, yes it does.
So we can say with all certainty that Micah is 28 years old, and Angela is 12.
Solve the linear equation - 7(x + 2) = -3(x - 5) for x
x= −29/4
Answer:
Step-by-step explanation:
−7(x+2)=−3(x−5)
Step 1: Simplify both sides of the equation.
−7(x+2)=−3(x−5)
(−7)(x)+(−7)(2)=(−3)(x)+(−3)(−5)(Distribute)
−7x+−14=−3x+15
−7x−14=−3x+15
Step 2: Add 3x to both sides.
−7x−14+3x=−3x+15+3x
−4x−14=15
Step 3: Add 14 to both sides.
−4x−14+14=15+14
−4x=29
Step 4: Divide both sides by -4.
−4x −4
x=29/−4
x= −29/4

In a board game a certain number of points is awarded to a player upon rolling a six sided die labeled 1 to 6 according to the function f(x)=2x+3 whereby is it he value rolled on the die fund and interpret the given functions values and determine an appropriate domain for the functions
Answer:
f(x) is the amount awarded to a player upon rolling the die
The domain of the function = 1, 2, 3, 4, 5, and 6
The values of the function are 5, 7, 9, 11, 13, and 15
Step-by-step explanation:
The given information includes;
The function f(x) = 2·x + 3
Given that f(x) is the amount awarded to a player upon rolling the die, and x = The value rolled on the die, we have;
The values of x are 1, 2, 3, 4, 5, and 6
The values of the function then becomes;
f(x) = 2·x + 3
{x = 1, 2, 3, 4, 5, and 6} {f(x) = 5, 7, 9, 11, 13, and 15}
Therefore, the domain of the function = 1, 2, 3, 4, 5, and 6
The values of the function are 5, 7, 9, 11, 13, and 15.

At football practice, Ty made 24 field goals, which was 80% of the field
goals he attempted. How many field goals did he attempt?
Answer:
30 field goals
Step-by-step explanation:
80 is 4/5 of 100. To find what to multiply 5 by, I will divide 24/4, since it is 4/5. 24/4 is 6, and 6*5 is 30. So, the answer is 30. To check, I know that 24 has four sixes within it, and 30 has five sixes within it. 4/5=4/5.
