Answer:
A and B.
Step-by-step explanation:
To get to know the graph with least slope, we have to write all equations in the form y=mx + c.where m is the slope and c is the the y-intercept.
A. y = x + 6
For this equation m = 1
B. y = -x - 9
For equation B, m = -1
C. y = 2x + 1
In this equation, m = 2
D. y = -7x - 2
In equation D, m = -7
The equation with the highest slope is D while the one with the least slope/steep is A and B.
Quadrilateral ABCD is a parallelogram if its diagonals bisect each other. Prove that Quadrilateral ABCD is a parallelogram by finding the value of x.
A) x = 2
B) x = 3
C) x =- 9|2
D) x = -3|4
Information that goes with the picture:
AO = 5x + 2
BO = x − 1
CO = 3x − 7
DO = 3x + 8
Because this is a parallelogram, we know that the diagonals bisect. This means that AO = DO, and CO = BO
It doesn't matter which two segments we use, but I'm going to use CO = BO for this one.
3x - 7 = x - 1
2x = 6
x = 3
Option B. is 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
Step-by-step explanation:
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.
write an equation of the line containing the specified point and perpendicular to indicated line. (-5,6) 4x-y=3
Answer:
y = [tex]\frac{1}{2}x + \frac{29}{4}[/tex]
Step-by-step explanation:
First, we need to rearrange the equation to make it y = mx + c
4x - y = 3
y + 3 = 4x
y = 4x -3
So the slope of the line is 4.
The slope of a line perpendicular to an equation is:
[tex]\frac{-1}{gradient}[/tex]
So the slope of the perpendicular line is:
[tex]\frac{-1}{4}[/tex] = -0.25
Now to find the equation of a line you can use the following equation:
y - y₁ = m(x - x₁)
Where y₁ is the y-coordinate, x₁ is the x-coordinate and m is the gradient. Plug the values in:
y₁ = 6
x₁ = -5
m = [tex]\frac{-1}{4}[/tex]
y - 6 = [tex]\frac{-1}{4}[/tex](x - - 5)
To get rid of the fraction we need to multiply the whole equation by 4:
4y - 24 = -1(x - - 5)
The two negatives cancel out:
4y - 24 = -1(x + 5)
Multiply the brackets out:
4y - 24 = -x + 5
Now, to rearrange the formula back into y = mx + c
Move the -24 over to the other side making it a +24:
4y = 2x + 5 + 24
4y = 2x + 29
Divide everything by 4:
y = [tex]\frac{2}{4}x + \frac{29}{4}[/tex]
y = [tex]\frac{1}{2}x + \frac{29}{4}[/tex]
Solve for k:
k + 6 > -20
Answer:
k > -26
Step-by-step explanation:
To isolate the k, you subtract 6 from both sides to get k < -26.
The correct answer is k > -26
Explanation:
To solve our equation first we need to set out our equation, k + 6 > -20. Next, we have to subtract 6 from both sides of the equation, k + 6 - 6 > -20 - 6 = k > -26. Finally, we have our answer of k > -26.

The measures of the angles of triangle ABC are given by the expressions in the table
What are the measures of angles A and C
m/A = ? Degrees
m/C = ? Degrees
Answer:
[tex]m<A=125\°[/tex]
[tex]m<B=35\°[/tex]
Step-by-step explanation:
step 1
Find the value of x
we know that
The sum of the interior angles in a triangle must be equal to 180 degrees
so
[tex]m<A+m<B+m<C=180\°[/tex]
substitute the values and solve for x
[tex](6x-1)\°+20\°+(x+14)\°=180\°[/tex]
[tex]7x=180\°-33\°[/tex]
[tex]7x=147\°[/tex]
[tex]x=147\°/7=21\°[/tex]
step 2
Find the measure of angle A
[tex]m<A=(6x-1)\°=6(21)-1=125\°[/tex]
step 3
Find the measure of angle C
[tex]m<C=(x+14)\°=21+14=35\°[/tex]

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%.

What is the area of a parallelogram ABCD
Answer:
Area of a parallelogram would be 13.46
Step-by-step explanation:
Since area of a parallelogram is represented by the formula
Area = [tex]\frac{1}{2}[/tex] ([tex](D_{1}*D_{2})[/tex]
Where [tex]D_{1}[/tex] and [tex]D_{2}[/tex] are two diagonals of the given parallelograms.
In the given figure [tex]D_{1}=AC[/tex] and [tex]D_{2}[/tex] = BD
We will find the length of [tex]D_{1}[/tex] and [tex]D_{2}[/tex] first
Since points A and C are (3,6) and (5,1)
So distance AC = [tex]\sqrt{(6-1)^{2}+(3-5)^{2} }[/tex]
= [tex]\sqrt{5^{2}+(-2)^{2}}[/tex]
= [tex]\sqrt{25+4}=\sqrt{29}[/tex]
Since B and D are the points (6, 5) and (2, 2)
So length of BD = [tex]\sqrt{(6-2)^{2}+(5-2)^{2}}[/tex]
BD = [tex]\sqrt{4^{2}+3^{2}}=\sqrt{25}=5[/tex]
Now we will put these values in the formula
Area of parallelogram = [tex]\frac{1}{2}(\sqrt{29})(5)[/tex]
= [tex]\frac{5}{2}[/tex] × [tex]\sqrt{29}[/tex]
= (2.5) (5.385)
= 13.46

Assume that the probability of a driver getting into an accident is 7.1%, the average cost of an accident is $14,886.05, and the overhead cost for an insurance company per insured driver is $110. What should the driver's insurance premium be?
A)$1156.43
B)$1242.93
C)$1276.27
D)$1165.49
Multiply the probability by the cost of the accident:
14,886.05 x 0.071 = 1056.91
Now add the overhead cost:
1056.91 + 110 = 1166.91
The closest answer to this is number D.
Answer:
D. $1165.49
Step-by-step explanation:
We have that the probability of a driver getting into an accident = 7.1% i.e. 0.071.
Now, the average cost of an accident = $14,886.05
Then, the expected cost of an accident = $14,886.05 × 0.071 = $1056.91
As, the overhead cost for insurance = $110
Therefore, the driver's insurance premium = $1056.91 + $110 = $1166.91
Since, the closest option to $1166.91 is option D.
Hence, the driver's insurance premium will be $1165.49.
Irene bought six pounds of fish for $12.90. Based on that cost, how much would 3.4 pounds of the same fish cost?
A) $2.15
B. $6.45
C) $7.31
D. $22.76
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.
Thus leading to, this fish would cost $6.45 for three pounds.

Total blood cholesterol level was measured for each of
8 adults. Here are the 8
measurements (in mg/dL):
264, 191, 160, 148, 262, 212, 268, 246
Step-by-step explanation:
Given blood cholesterol level was measured for each of 8 adults (in mg/dL) are:
264, 191, 160, 148, 262, 212, 268, 246
In order to find the mean, we need to add all those 8 numbers and divide by 8.
Therefore, mean = [tex]\frac{264+191+160+148+262+212+268+246}{8} =\frac{1751}{8} =218.9.[/tex]
Mean = 218.9.In order to find the median, we need to arrange them in ascending order:
148, 160, 191, 212, 246, 262, 264, 268.
The middle most two values are 212 and 246.
Therefore, median = [tex]\frac{212+246}{2} =\frac{458}{2} = 229.[/tex]
Median = 229.[tex]\mathrm{The\:mode\:is\:the\:term\:in\:the\:data\:set\:that\:appears\:the\:most.}[/tex]

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

Which of the following equations represents a degenerate ellipse?
Answer: [tex]\frac{x^2}{10} = -\frac{y^2}{18}[/tex]
Step-by-step explanation:
Since, The degenerate form of an ellipse is always a point.
Thus, the equation that shows only a point will be our answer.
Since [tex]9x^2 + 4y^2 = 1[/tex] is the equation of an ellipse,
Thus, It can not be a point.
[tex]\frac{x^2}{14} + \frac{y^2}{19} =2[/tex] is not a point ( because it is an equation of ellipse)
But, when we plot [tex]\frac{x^2}{10} = -\frac{y^2}{18}[/tex]
We get only a point (0,0).
Thus, equation, [tex]\frac{x^2}{10} = -\frac{y^2}{18}[/tex] shows only one point.
Therefore, it is a generated form of ellipse.
The equation representing a degenerate ellipse would have the sum of the distances from the foci to any point on the curve as a constant.
Explanation:An ellipse is a closed curve such that the sum of the distances from a point on the curve to the two foci is constant. So, the equation representing a degenerate ellipse would have the sum of the distances from the foci to any point on the curve as a constant. The correct equation is (b).
