Answer:
8 months
Step-by-step explanation:
Given that:
Amount of money present in the bank account = $2,571.68
Automatic monthly rental payments for car loan = $321.46
Any deposits in the bank account are stopped.
To find:
The number of months taken so that the automatic payments make the value of the account as zero?
Solution:
Let the number of months taken to make the value of the account zero = [tex]m[/tex] months
To find the value of [tex]m[/tex], we need to divide the total amount initially present in bank account with the monthly rental payment amount.
Therefore, the equation to find the value of [tex]m[/tex], can be written as:
[tex]m = \dfrac{2571.68}{321.46}[/tex]
On solving the above equation, we get the value as following:
[tex]\bold{m=8}[/tex] months

Which function has an inverse that is a function
Answer:
Options (1) and (3)
Step-by-step explanation:
Option (1)
f(x) = x²+ 3
We can rewrite the function in the equation form as,
y = x² + 3
By interchanging y by x,
x = y² + 3
Now we solve it for y,
y² = x - 3
y = ±√(x - 3)
So the inverse function is,
[tex]f^{-1}(x)=\pm \sqrt{x-3}[/tex]
It's a function.
Option 2
d(x) = -9
Equation form of the function is,
y = -9
Replacing y by x,
x = - 9
Therefore, inverse function will be,
x = -9
Inverse is not a function
Option 3
m(x) = -7x
Equation form of the function,
y = -7x
Interchanging y by x,
x = -7y
Now solve for x,
y = [tex]-\frac{1}{7}x[/tex]
So the inverse function will be,
[tex]m^{-1}(x)=-\frac{1}{7}x[/tex]
Inverse is a function.
Option 4
p(x) = |x|
As this function not a one to one function inverse function is not possible.
Inverse of |x| is not a function.

A volunteer made m muffins for the bake sale. After selling 28 muffins, 21 muffins remained. Write and solve an algebraic equation to find how many muffins she originally made. *
Answer:
The original amount of muffin she original made will be: m = 49
Step-by-step explanation:
Let 'm' be the muffins made for the bake sale.Given that after selling 28 muffins, 21 muffins remained.
Thus, the equation becomes
[tex]m - 28 = 21[/tex]
adding 28 to both sides
[tex]m-28+28 = 21+28[/tex]
[tex]m = 49[/tex]
Therefore, we conclude that the original amount of muffin she original made will be: m = 49

Christine needs to make a total of 40 deliveries this week. So far she has completed 14 of them . What percentage of her total deliveries has Christine completed?
Answer:
Christine has completed 35% of her total deliveries.
Step-by-step explanation:
To find the answer, you can use a rule of three considering that as Christine needs to make a total of 40 deliveries this week, this would represent 100% and with this you can find the percentage that the 14 deliveries completed represent:
40 → 100%
14 → x
x=(14*100)/40=35%
According to this, the answer is that Christine has completed 35% of her total deliveries.

Answer:
(6x - 1) • (2x + 9)
Step-by-step explanation:
STEP
1
:
Equation at the end of step 1
((22•3x2) + 52x) - 9
STEP
2
:
Trying to factor by splitting the middle term
2.1 Factoring 12x2+52x-9
The first term is, 12x2 its coefficient is 12 .
The middle term is, +52x its coefficient is 52 .
The last term, "the constant", is -9
Step-1 : Multiply the coefficient of the first term by the constant 12 • -9 = -108
Step-2 : Find two factors of -108 whose sum equals the coefficient of the middle term, which is 52 .
-108 + 1 = -107
-54 + 2 = -52
-36 + 3 = -33
-27 + 4 = -23
-18 + 6 = -12
-12 + 9 = -3
-9 + 12 = 3
-6 + 18 = 12
-4 + 27 = 23
-3 + 36 = 33
-2 + 54 = 52 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -2 and 54
12x2 - 2x + 54x - 9
Step-4 : Add up the first 2 terms, pulling out like factors :
2x • (6x-1)
Add up the last 2 terms, pulling out common factors :
9 • (6x-1)
Step-5 : Add up the four terms of step 4 :
(2x+9) • (6x-1)
Which is the desired factorization

If you were offered $18 dollars per hour, $3,000 dollars a month or $37,000 dollars a year, which would you take if salary was the only consideration?
Answer:
I will consider $18/hour pay
Step-by-step explanation:
Before we an know which of the money to consider, we need to converted the equivalent amount in years
If $18 dollars is offered per hour, to know the equivalent amount per year.
1year = 8760hour
$18 = 1hr
x = 8760hr
x =18×8760
x = $157680
For the monthly pay
$3000 = 1month
y =12months
Since 12months are in year
Cross multiply
y = 3000×12
y = $36000
Since the hourly pay equivalent in years is greater than the monthly and yearly pay, hence I would consider $18 per hour pay

Answer:
a. Geometric
b. 20, 10 and 5
c. Tn = 20(0.5)^n-1
d. 0.00004 ft
Step-by-step explanation:
a. The sequence is geometric
The reason for this is that we will be multiplying each term by a particular value
If it was arithmetic, we would have been adding instead. But since it is geometric, we shall multiply terms by a particular number
b. 1st term is
20
second term
1/2 * 20 = 10
Third term
1/2 * 10 = 5
c. Explicit formula
Mathematically, that will be;
Tn = ar^n-1
Where r is 1/2 or 0.5
Tn = a(0.5)^n-1
where Tn is the present term and n is the present number of the term
d. 20th term
T20 = 20 * 0.5^19
T20 = 0.00004 ft

Answer:
[tex]x = \frac{ - 3}{2} \: or \: \frac{1}{3} [/tex]
Step-by-step explanation:
[tex]7 {x}^{2} + 10x - 3 = {x}^{2} + 3x[/tex]
[tex] = > 7 {x}^{2} - {x}^{2} + 10x - 3x -3 = 0[/tex]

Well's College in New York was previously an all girls school. In 2005, the college began to allow boys to enroll. By 2012, the ratio of boys to girls was 3:7. If there were 200 more girls than boys, how many boys were enrolled that year?
Answer: 150 boys
Step-by-step explanation:
Let the number of boys be x
Since there were 200 more girls than boys, the number of girls will be: = x + 200
Since the ratio of boys to girls was 3:7, this can be solved further below:
3/7 = x/x+200
Cross multiply
(7 × x) = 3(x + 200)
7x = 3x + 600
7x - 3x = 600
4x = 600
x = 600/4
x = 150
The number of boys enrolled is 150
Number of Girls will be:
= X + 200
= 150 + 200
= 350
Check: Number of boys / Number of girls
= 150/350
= 3/7
= 3:7
Add (16n2 + n + 1) + (4n2 - 5n - 2).
Answer:
20n2-4n-1
Step-by-step explanation:
You combine like terms, so you add 16n2 with 4n2 to get 20n2. Then you add n with -5n to get -4n. Finally, you add 1 with -2 to get -1.

A student is solving the equation 21 y + 3) = 14 for y. Which of these could be the next step?
1. Distribute on the left hand side to get 2y +3 = 14
2. Divide both sides by 2 to get y+3 = 7
3. Distribute on the left hand side to get 2y +6 = 14
4. Subtract 3 from both sides to get 2y = 11
5. Divide both sides by 2 to get y+3 = 14

If x = 6 and y = –2, evaluate the following expression:
7(2x – 3y)
Answer:
14x-21y
Step-by-step explanation:
To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. This is:
7(2x – 3y)
= 7(2(6) – 3(-2))
= 7(12 + 6)
= 7(18)
= 126
