Answer: Inconsistent
Step-by-step explanation:
y = 3x + 4 → m = 3, b = 4
y = 3x + 3 → m = 3, b = 3
These equations have the same slope but different y-intercepts so they are parallel lines which means they will never intersect.

Andy has 9 math books and 6 reading books. If he wants to distribute them evenly among some bookshelves so that each has the same combination of books, with none left over, what is the greatest number of bookshelves Andy can use?
Answer:
3 is the greatest number of book shelves Andy can use.
Step-by-step explanation:
You can solve this by finding the greatest common factor of 9 and 6, which turned out to be 3.
6/3 = 2 (reading books per shelf)
9/3 =3 (math books per shelf)
Every shelf there are 2 reading books and 3 math books.

Perform the specified operations on the polynomials: Subtract 5a−6b+7c from 13a−4b+8c
Answer:
8a + 2b + c
Step-by-step explanation:
For subtracting polynomials we just need to operate subtracting the terms with same unknown. In our case we sum/subtract the terms that include a between them, the terms that have b between them and the therms with c between them. So we have:
(13a−4b+8c) - (5a−6b+7c) =?
13a−4b+8c - 5a+6b-7c = ?
Lets operate putting together terms with same unknown:
(13a - 5a) + (-4b +6b) + (8c-7c) =
8a + 2b + c
So, if we subtract 5a−6b+7c from 13a−4b+8c we get 8a + 2b + c

Geometry; Inscribed Angles.Find the value of y. Please explain!
check the picture below.
Answer:
y = 48° is the answer.
Step-by-step explanation:
In the figure attached, length of small arc = 66°
This small arc makes an angle at the center of the circle = 66°
By definition, angle formed by the arc at the center is double of the measure of the angle inscribed by the small arc at the point on a circle.
Therefore, m (arc) = 66° = 2.(x)
x = [tex]\frac{66}{2}=33[/tex]
Similarly, y = [tex]\frac{96}{2}=48[/tex]
y = 48° will be the answer.
Calculate a5 for the geometric sequence in which a1=1600 and the common ratio is 3/4.
Answer:
a₅ = 506.25 option a
Step-by-step explanation:
Given that,
first term a₁ = 1600
common ratio (r) = [tex]\frac{3}{4}[/tex]
We need to find the fifth term of the geometric progression
We know that the nth term formula
aₙ = a₁rⁿ-¹
where a₁ is first term and r is the common ratio
n is the number of terms
So, n = 5
a₅ = 1600 [tex](\frac{3}{4})^{5-1}[/tex]
a₅ = 1600*[tex](\frac{3}{4}) ^{4}[/tex]
a₅ = 1600*81/256
a₅ = [tex]\frac{2025}{4}[/tex]
a₅ = 506.25 option a
That's the final answer
Answer:
A. 506.25

Compound Interest: A = P ( 1 + r/n )^nt
Answer:
14905.85
Step-by-step explanation:
P(1+r/n)^nt
10000 (1 + (.05/12))^ (12*8)
Answer:
she will have $14,906 in December of year 2018
Step-by-step explanation:
To find the amount of money she will have in December of the year 2018, we will simply use the formula;
Compound Interest: A = P ( 1 + r/n )^nt
where p = principal
R = rate
n = the number of times the interest is compounded per unit time
T = time
A= Accrued amount
From the question
Principal (p) = $10,000
Rate (r) = 5% = 0.05
Time(t) = 2018-2010 = 8 years
n = 12
We can now proceed to insert the values into our formula;
Compound Interest: A = P ( 1 + r/n )^nt
= $10 000 ( 1 + 0.05/12) ^12×8
=$10,000(1 + 0.00416667)^96
= $10 000(1.00416667)^96
=$10 000(1.4905859)
=$14,905.895
≈$14,906 to the nearest whole number.
Therefore she will have $14,906 in December of year 2018

use the following table to find the value of h'(3) if h(x)=g[f(x)]
A differential equation is an equation that contains one or more functions with its derivatives. The value of h'(3) iss 14.
What is Differential equation?A differential equation is an equation that contains one or more functions with its derivatives.
Given
h(x) = g(f(x))
Let us differentiate with respect to x by using chain rule we get
h'(x) = g'(f(x))f'(x)
plug the value x =3 in the above equation
h'(3) = g'(f(3))f'(3)
The value of f(3)=4, f'(3)=7 by table given
Plugging in values we get
h'(3) = g'(4)×7
We have g'(4)=2
so h'(3) = 2×7
h'(3) = 14
Hence the value of h'(3) is 14.

Please help.
Answer:
B. 6.45
Step-by-step explanation:
So we know that you bought six pounds for $12.90, and you need to know how much it would cost for three pounds. You need to find out what one pound would cost, then multiply that by three.
You would do:
12.90 ÷ 6
Which equals : 2.15
Then take that and multiply it by 3:
2.15 × 3
Giving you 6.45.

Answer:
see explanation
Step-by-step explanation:
to find the first, fourth and tenth terms, substitute n = 1, 4, 10 into the rule
A(1) = - 3 + (1 - 1)(- 2.2) = - 3 + (0 × - 2.2) = - 3 + 0 = - 3
A(4) = - 3 + (4 - 1)(- 2.2) = - 3 + (3 × - 2.2) = - 3 - 6.6 = - 9.6
A(10) = - 3 + (10 - 1)(- 2.2) = - 3 + (9 × - 2.2) = - 3 - 19.8 = - 22.8

Alissa would like to make a deposit into her savings account. She filled out a deposit ticket and handed it to the teller at her bank. The teller apologizes to Alissa and explains that she cannot accept the deposit ticket in its current form. Determine what, if anything, Alissa will have to change in order for her deposit ticket to be accepted. a. The sub total is calculated incorrectly b. Alissa forgot to sign the deposit ticket for less cash back c. The total is calculated incorrectly d. Alissa forgot to date the deposit ticket
The correct option is c. The total is calculated incorrectly.
When making a deposit, it is crucial that the total amount being deposited is calculated correctly on the deposit ticket. This total amount should match the sum of the cash and checks being deposited. If there is a discrepancy between the subtotal of the individual amounts and the total, the deposit ticket will not be accepted because it does not accurately reflect the amount of money being handled.
Here's the logic behind why the other options are not the primary issue:
a. The sub total is calculated incorrectly: While this is a potential error, the primary concern for the teller would be the total amount being deposited. The subtotal informs the depositor and the bank of the breakdown of the deposit, but the total is what ultimately needs to be correct for the deposit to be processed accurately.
b. Alissa forgot to sign the deposit ticket for less cash back: While a signature is important for verification purposes, especially if cash back is requested, the absence of a signature would typically result in the teller asking for a signature rather than outright rejection of the deposit ticket. The calculation of the total deposit amount is a more fundamental error that must be corrected before the deposit can be accepted.
d. Alissa forgot to date the deposit ticket: The date on a deposit ticket is important for record-keeping purposes. However, forgetting to date the deposit ticket is usually a minor issue that can be resolved quickly at the teller's window. It would not typically prevent the deposit from being accepted, assuming the total deposit amount is correct.
In summary, the teller's refusal to accept the deposit ticket in its current form most likely stems from an incorrect total calculation, as this directly affects the accuracy of the deposit transaction. Alissa will need to ensure that the total on the deposit ticket correctly reflects the sum of the cash and checks she is depositing. Once the total is corrected, the deposit ticket should be accepted by the teller.

2. 2. (7.RP.3) Sylvia bought a 6-month $1900 certificate of deposit. At the end of 6 months, she received a $209 simple interest. What rate of interest did the certificate pay? Show all of your work.
Answer:
1. c. $450.
2. 22%
Step-by-step explanation:
1. We will use simple interest formula to find the amount of interest after 2 years on $5,000. As interest is not compounded, so it will not matter if she moves the simple interest earned in separate account or not.
[tex]I=P*r*t[/tex], where,
I= Amount of interest.
P= Principal amount.
r= Interest rate in decimal form.
t= Time in years.
[tex]4.5\text{ percent}=\frac{4.5}{100}=0.045[/tex]
Upon substituting our given values in above formula we will get,
[tex]I=5000*0.045*2[/tex]
[tex]I=5000*0.09[/tex]
[tex]I=450[/tex]
Therefore, Tracy will get an amount of $450 as simple interest after 2 years and option c is the correct choice.
2. Sylvia bought a 6-month $1900 certificate of deposit. At the end of 6 months, she received a $209 simple interest.
6 months is same as 1/2 year.
[tex]I=P*r*t[/tex]
Upon substituting our given values in above formula we will get,
[tex]209=1900*r*\frac{1}{2}[/tex]
[tex]209=950*r[/tex]
[tex]r=\frac{209}{950}[/tex]
[tex]r=0.22[/tex]
Since interest rate is in decimal form, let us convert it in percent.
[tex]\text{Interest rate}=0.22\times 100=22\text{ percent}[/tex]
Therefore, interest rate of certificate of deposit was 22%.
