For the given coordinate plane the letters A, B, C and D represent the y-axis, first quadrant, origin and x-axis respectively.
What is a coordinate plane?A coordinate plane can be defined as the surface formed by two perpendicular lines which intersect each other. The vertical and horizontal lines are known as y and x axis respectively.
The intersection of these lines is known as the origin.
The diagram of the coordinate plane can be analysed as,
(a) Line A is the vertical perpendicular line.
It can be called as y-axis.
(b) Region B lies in the part of the coordinate plane where x and y coordinates are positive.
It is known as the first quadrant.
(c) Point C lies at the intersection of two lines perpendicular to each other.
It can be said the origin.
(d) Line D is the horizontal line.
It can be called as x-axis.
Hence, the given letters A, B, C and D represent the y-axis, first quadrant, origin and x-axis respectively.

A car costs 20% less this year than last year. Last year, the car cost 5% less than the year before. The price of the car this year is $9,400. How much did the car cost 2 years ago?
Answer:
The answer is 11,374
Step-by-step explanation:
First we find 5% of 9,400 is.
9,400 * 5% = 470
Next we add 9,400 with 470 then multiply by 20%
9,400 + 470 = 9,870
9,870 * 20% = 1974
Next we add.
9,870 + 1,974 = 11,374
So, the answer is 11,374

On Monday Sylvia spent 5/12 of a day driving to her cousins house. On Friday she spent the same amount of time driving home. What fraction of a day did Sylvia spend driving to her cousins house and back?
Answer: The fraction of a day did Sylvia spend driving to her cousins house and back = [tex]\dfrac{5}{6}[/tex]
Step-by-step explanation:
Given: Fraction of day Sylvia spent to drive her cousins home = [tex]\dfrac5{12}[/tex]
Fraction of day Sylvia spent to drive her home back= [tex]\dfrac5{12}[/tex]
Total fraction of day Sylvia spend driving to her cousins house and back = [tex]\dfrac5{12}+\dfrac{5}{12}[/tex]
[tex]=\dfrac{5+5}{12}\\\\=\dfrac{10}{12}\\\\=\dfrac{5}{6}[/tex]
Hence, the fraction of a day did Sylvia spend driving to her cousins house and back = [tex]\dfrac{5}{6}[/tex]

Step-by-step explanation:
Jo sold 132 mugs. One quarter of the mugs were small. The rest were large. How many small mugs did Jo sell? * 1 point
Answer:
33 small mugs
Step-by-step explanation:
Given:
Total number of mugs sold by Jo = 132
One quarter of the mugs were small. The rest were large.
To find: Number of small mugs sold by Jo
Solution:
Number of small mugs sold by Jo = [tex]\frac{1}{4}[/tex] (Total number of mugs sold by Jo)
Therefore,
Number of small mugs sold by Jo [tex]=\frac{1}{4}(132)=33[/tex]
Find the solution of the system of equations -7x-3y=-20 3x+6y=-15
9514 1404 393
Answer:
(5, -5)
Step-by-step explanation:
I like a graphing calculator for quickly finding a solution to a system of equations. It shows the solution to be (5, -5).
__
We can add the second equation to 2 times the first to eliminate the y-variable.
2(-7x -3y) +(3x +6y) = 2(-20) +(-15)
-11x = -55 . . . . . collect terms
x = 5 . . . . . . . . . divide by -11
Substituting this value into the second equation, we have ...
3(5) +6y = -15
6y = -30 . . . . . . . . subtract 15
y = -5 . . . . . . . . . . divide by 6
The solution is (x, y) = (5, -5).

The angle of a triangle are in the ratio 3:7:8. Find the angles.
Answer:
30°, 70°, 80°
Step-by-step explanation:
Let the measures of the angles be 3x, 7x and 8x.
Since, sum of the measures of all the three angles of a triangle is 180°.
Therefore,.
3x + 7x + 8x = 180°
18x = 180°
x = 180°/18
x = 10°
3x = 3*10° = 30°
7x = 7*10° = 70°
8x = 8*10° = 80°
Thus, the measures of the angles are 30°, 70°, 80°.
Serenity invested $3,100 in an account paying an interest rate of 2.9% compounded continuously. Assuming no deposits or withdrawals are made, how much money, to the nearest dollar, would be in the account after 12 years?
Answer:
$4179
Step-by-step explanation:
3,100*.029= 89.9
89.9*12=1,078.80
3,100+1,078.80=4,178.80
4,178.80 rounded to the nearest dollar= 4179
The amount of money in the account after 12 years would be $4,371.
What is Compound interest?Compound interest is defined as interest paid on the original principal and the interest earned on the interest of the principal.
To calculate the amount of money in the account after 12 years, we need to use the formula for continuously compounded interest, which is:
A = P[tex]e^{rt}[/tex]
where A is the final amount, P is the principal (initial amount invested), r is the annual interest rate, and t is the number of years the money is invested.
In this case, the initial amount invested is $3,100, the annual interest rate is 2.9%, and the number of years is 12.
Plugging these values into the formula, we get:
A = $3,100 × [tex]e^{0.029 \times 12)[/tex]
A = $3,100 × [tex]e^{0.348}[/tex]
A = $3,100 × 1.41
A = $4,371
Therefore, the amount of money in the account after 12 years, to the nearest dollar, would be $4,371.
