Hey there!
First, we'll solve for x = 0.
The first step is to replace x with 0 anytime it appears in the equation.
f(0) = 7(0) + 2
Multiply 7 by 0 next because multiplication comes before addition in PEMDAS.
f(0) = 0 + 2
Then, add 2 to 0 since it is the last step.
f(0) = 2 The value of f(x) when x = 0 is 2.
Now we can solve for x = 1.
The first step is to replace x with 1 anytime it appears in the equation.
f(1) = 7(1) + 2
Multiply 7 by 1 next because multiplication comes before addition in PEMDAS.
f(1) = 7 + 2
Then, add 2 to 7 because it is the last step.
f(1) = 9 The value of f(x) when x = 1 is 9.
Hope this helps!

Hasan has 18 3/4 yards of fabric. it takes 3 1/6 yards to make a pillowcase. hasan plans to amke as many pillowcases as he can. how many yards of fabric will be left over?
Final answer:
To make as many pillowcases as Hasan can with 18 3/4 yards of fabric, we divide the total amount of fabric by the amount needed for one pillowcase and then find the remainder.
Explanation:
To find out how many pillowcases Hasan can make, we need to divide the total amount of fabric he has (18 3/4 yards) by the amount of fabric needed to make one pillowcase (3 1/6 yards).
First, let's convert 18 3/4 yards to an improper fraction: 18 3/4 = 75/4.
Next, let's convert 3 1/6 yards to an improper fraction: 3 1/6 = 19/6.
Now, we can divide 75/4 by 19/6 using the division of fractions: (75/4) ÷ (19/6) = (75/4) x (6/19) = 450/76 = 75/19.
So Hasan can make 75/19 pillowcases. To find out how many yards of fabric will be left over, we need to subtract the amount used for the pillowcases from the total amount of fabric. Let's multiply the number of pillowcases (75/19) by the amount of fabric used per pillowcase (3 1/6 yards): (75/19) x (19/6) = 75/6 = 12 3/6 yards.
Therefore, Hasan will have 12 3/6 yards of fabric left over.

Given
AB and CD intersect
AC, CB, BD and AD are congruent.
Prove that AB is the bisector of ∠CAD and ray CD is the bisector of ∠ACB.
and AB and CD are perpendicular.
To proof
Bisector
A bisector is that which cut an angle in two equal parts.
In ΔACB and ΔADB
AD = AC ( Given )
AB = AB ( common )
BC = DB ( Given )
by SSS congurence property
we have
ΔACB ≅ΔADB
∠CAB =∠ DAB
∠CBA = ∠DBA
( By corresponding sides of the congurent triangle )
Thus AB is the bisector of the ∠CAD.
InΔ DAC and ΔDBC
AD = DB (Given)
AC = CB ( Given )
CD = CD (common)
By SSS congurence property
ΔDAC≅ Δ DBC
∠ ACD =∠ BCD
∠ADC =∠BDC
( By corresponding sides of the congurent triangle )
Therefore CD is the bisector of the CAD.
In ΔBOC andΔ BOD
BO = BO ( Common )
∠BCO = ∠BDO
( As prove above ΔACB ≅ΔADB
Thus ∠ACB = ∠ADB by corresponding sides of the congurent triangle , CD is a bisector
∠BCO = ∠BDO )
CB = DB ( given )
by SAS congurence property
ΔBOC ≅ ΔBOD
∠BOC =∠ BOD
∠BOC +∠ BOD = 180 °( Linear pair )
2∠ BOC = 180°
∠BOC = 90°
∠BOC =∠ BOD = 90°
also
In ΔCOA and ΔAOD
AO = AO ( Common )
∠ACO =∠ ADO
( As prove above ΔACB ≅ΔADB Thus ACB = ADB by corresponding sides of congurent triangle ,CD is a bisector
thus ∠ACO = ∠ADO )
AC =AD ( given )
by SAS congurence property
Δ COA ≅ ΔAOD
∠AOC = ∠AOD
( By corresponding angle of corresponding sides )
∠AOC + ∠AOD = 180°
2∠ AOC = 180° ( Linear pair )
∠AOC = 90°
∠AOC = ∠AOD = 90 °
Thus AB and CD are perpendicular.

Please Use the factor theorem to determine whether v + 5 is a factor of v^4 + 16v^3 + 18v^2 -725
A. Yes
B. No
Substituting [tex]\( v = -5 \)[/tex] into the polynomial yields -650, not zero. Thus, [tex]\( v + 5 \)[/tex] is not a factor. Answer: B. No.
To determine whether [tex]\( v + 5 \)[/tex] is a factor of [tex]\( v^4 + 16v^3 + 18v^2 - 725 \)[/tex], we can use the Factor Theorem. According to the Factor Theorem, if [tex]\( v + 5 \)[/tex] is a factor of the polynomial, then [tex]\( v = -5 \)[/tex] must be a root (or zero) of the polynomial.
Step 1: Substitute [tex]\( v = -5 \)[/tex] into the polynomial.
[tex]\[ (-5)^4 + 16(-5)^3 + 18(-5)^2 - 725 \][/tex]
Step 2: Calculate the value.
[tex]\[ 625 - 2000 + 450 - 725 \][/tex]
[tex]\[ = -650 \][/tex]
Since the value is not zero, [tex]\( v + 5 \)[/tex] is not a factor of [tex]\( v^4 + 16v^3 + 18v^2 - 725 \).[/tex]

Which of the following is a liability? a. bonus paycheck b. credit card balance c. investment fund d. savings account Please select the best answer from the choices provided
Answer:
Option b) A credit card balance
Step-by-step explanation:
The credit card balance shows the amount you owe to the bank for purchases using credit card.
Credit card is meant for purchases without paying money actualy and after a fixed period paying to the bank full amount outstanding.
Periodically, all credit card transactions will be listed and sent to the customer with a due date within which the amount is to be paid.
IF amount is not paid within due date, a penalty will be charged besides interest for the delay.
Thus credit card balance is a liability since it is the amount due or amount outstanding to be paid to the bank within a certain period. This can be treated as current liability

Solve the following systems of equations algebraically. Verify your solution either graphically or by using matrices.
3x - y=0
5x + 2y=22
3x - y=0
5x + 2y=22
Solve the first equation for y
3x - y =0
-y = -3x
so y = 3x
Now plug in y=3x in second equation
5x + 2y=22
5x + 2(3x) =22
5x + 6x = 22
11x = 22
Divide by 11 on both sides
x= 2
Plug in 2 for x and find out y
y = 3x
y = 3(2) = 6
Solution is (2,6)

What is the fourth term of the sequence 4, 8, 12, 16, 20, 24, . . .?
The fourth term of the arithmetic sequence 4, 8, 12, 16, 20, 24, ... is 16, which can be found either by adding the common difference to the third term or by using the formula for the nth term of an arithmetic sequence.
Explanation:The fourth term of the sequence 4, 8, 12, 16, 20, 24, ... can be determined by looking at the pattern of the sequence. This sequence is an arithmetic sequence, where each term increases by the same amount, which is 4 in this case. To find the fourth term, we can simply add the common difference (4) to the third term (12), which gives us 16. Alternatively, we can use the formula for the nth term of an arithmetic sequence, which is an = a1 + (n - 1)d, where a1 is the first term, d is the common difference, and n is the term number. Using this formula with a1 = 4, d = 4, and n = 4, we again get the fourth term as 16.
