Answer:
y(2x+3y-6)
Step-by-step explanation:
2xy+ [tex]3y^{2}[/tex]-6y
Find the H.C.F
2xy= 2×x×y
3y²= 3×y×y
6y= 6×y
H.C.F= y
2xy÷y+ 3y²÷y- 6y÷y
= 2x+ 3y- 6
= y( 2x+ 3y-6)
In the diagram below,AB is the diameter of the circle with centre P.Point C lies on the y-axis.Given the coordinates of A and B are (-6,3) and (2,-3) respectively ,calculate
a)the coordinates of P
b)radius of the circle
c)the coordinates of C
d)the area of the circle in term of
[tex]\pi[/tex]
Answer:
The coordinates of P are (-2,0)
The radius of the circle is 5.
Step-by-step explanation:
Analytic geometry
The diagram shows a circle with center P, and two points A(-6,3) and B(2,-3) that form the diameter of the circle.
a)
The center of the circle lies at the midpoint of A and B. The midpoint (xm,ym) can be calculated by:
[tex]\displaystyle x_m=\frac{x_1+x_2}{2}[/tex]
[tex]\displaystyle y_m=\frac{y_1+y_2}{2}[/tex]
Substituting x1=-6, x2=2, y1=3, y2=-3:
[tex]\displaystyle x_m=\frac{-6+2}{2}=\frac{-4}{2}=-2[/tex]
[tex]\displaystyle y_m=\frac{3-3}{2}=0[/tex]
Thus, the coordinates of P are (-2,0)
b) The radius of the circle is the distance from the center to any point in its circumference. We can use the distance from P to A or B indistinctly.
Given two points A(x1,y1) and P(x2,y2), the distance between them is:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Substituting x1=-6, x2=-2, y1=3, y2=0:
[tex]r=\sqrt{(-2+6)^2+(0-3)^2}[/tex]
[tex]r=\sqrt{4^2+(-3)^2}[/tex]
[tex]r=\sqrt{16+9}=\sqrt{25}=5[/tex]
The radius of the circle is 5.
Triangle ABC has vertices A(-3, -5), B(0, 4), and C(2, 5).
Which statement about triangle ABC is true?
A. Since two of the sides have slopes that are negative reciprocals, it is a right triangle.
B. Since two of the sides are congruent, it is a right triangle.
C. Since none of the sides have slopes that are negative reciprocals, it is not a right triangle.
D. Since none of the sides are congruent, it is not a right triangle.
Answer:
D. Since none of the sides are congruent, it is not a right triangle.
Step-by-step explanation:
This is the weirdest triangle I've ever seen.
Since none of the sides have slopes that are negative reciprocals, it is not a right triangle. Therefore, option C is the correct answer.
The given triangle ABC has vertices A(-3, -5), B(0, 4) and C(2, 5).
What is slope of a line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The formula to find the slope of a line is slope = (y2-y1)/(x2-x1)
Here, slope of AB is
m= (4+5)/(0+3)
= 3
Slope of BC is
m= (5-4)/(2-0)
= 1/2
= 0.5
Slope of CA is
m= (5+3)/(2+3)
= 8/5
= 1.6
Since none of the sides have slopes that are negative reciprocals, it is not a right triangle. Therefore, option C is the correct answer.

Alexander was given a gift card for a coffee shop. Each morning, alexander uses the card to buy one cup of coffee. Each cup of coffee costs $1.50 and after buying 4 cups of coffee , the card had a $9 remaining balance. Write an equation for A in terms of x
Answer:
A = (cost per cup of coffee * number of cups) + balance
$15
Step-by-step explanation:
Given that :
Cost per cup of coffee = $1.50
Number of cups purchased = 4
Balance on card = $9
Let A = worth of gift card
A = (cost per cup of coffee * number of cups) + balance
A = (1.50 * 4) + 9
A = 6 + 9

What is the value of x?
Answer:
x=131
Step-by-step explanation:

Which table contains only corresponding x - values and y - values where the value of y is 3 more than the quotient of x and 2?
Answer:
Step-by-step explanation:
Think its g
From the solution, we can see that the table that tally is the table G.
If the value of y is 3 more than the quotient of x and 2, the required function is expressed mathematically as;
[tex]y=\frac{x}{2} + 3[/tex]
To get the corresponding value that satisfies the equation, we will substitute the values of "x" to get the corresponding value of y
If x = 7
[tex]y=\frac{7}{2} + 3\\y=3.5 + 3\\y=6.5\\[/tex]
Checking one more value of x;
If x = 10
[tex]y=\frac{10}{2} + 3\\y=5 + 3\\y=8\\[/tex]
From the solution above, we can see that the table that tally is the table G.

Maria made some purchses at the Sunflower Market. She bought strawberries for $3.50, carrots for $2.25 and a bouquet of flowers for $9.95. If Maria uses a 20% coupon and has to pay 5.5% tax, how much will she pay in total? (Round your answer to the nearest hundredth)
Answer:
$13.25
Step-by-step explanation:
First you add everything up to get you to $15.70, then the 20% is changed to .2 which you then multiply 15.70 by .2 giving you 3.14. You then take 15.70 minus 3.14 which then gets you to 12.56. Then you take the tax of 5.5% and times $12.56 by it, giving you 69 cents, as your tax. Add those together to get 13.25, and then your finished.
Answer:
$13.25
Step-by-step explanation:
First let's add together the cost of all the items Maria bought:
3.50 + 2.25 + 9.95 = 15.70
The total cost of all the items without a coupon or tax is $15.70.
If Maria uses a 20% coupon, the value of the total cost will be 80% of its original value. So, multiply 15.7 by 0.8 to find the cost after the coupon:
15.7 * 0.8 = 12.56
The new total cost is 12.56. Now we need to find the sales tax. Multiply 12.56 by 0.055 to find the value of the sales tax:
12.56 * 0.055 = 0.6908
0.6908 rounds to 0.69. Add the cost of the sales tax to the total cost to get the final answer:
12.56 + 0.69 = 13.25
The total cost Maria will pay is $13.25

What is the Pythagoras theorem?
A fundamental concept in geometry that has to do with right triangles is the Pythagorean theorem. After the Greek mathematician Pythagoras, it establishes a link between the lengths of the sides of a right triangle.
According to the theorem, the square of the hypotenuse's length (the side that faces the right angle) in a right triangle equals the sum of the squares of the lengths of the other two sides.

A figure has the following vertices: A(0,5), B(8,3), C(6,0). What are the vertices of the
figure after a reflection across the y-axis?
Answer:
(0, 5), (-8, 3), (-6, 0)
Step-by-step explanation:
(0, 5) reflected across the y-axis = (0, 5)
(8, 3) reflected across the y-axis = (-8, 3)
(6, 0) reflected across the y-axis = (-6, 0)
Since the reflection is across the y-axis, we have to switch all of the x-values signs from positive to negative to get them from the top right side of the graph (positive side) to the top left side of the graph (negative side).
The only exception in this case is with the x-value 0 because 0 can never be negative or positive and remains in the middle of the graph.
Laura invests $3600 in a savings account for 2 years. The account pays 3.52% compound interest per annum. Laura has to pay 40% tax on the interest earned each year. The tax is taken from the account at the end of each year. How much is in the account at the end of 2 years?
Answer:
$3753.64
Step-by-step explanation:
Initial amount = $3600
Interest rate = 3.52%
n = 1 (once in a year)
Time = 1 years
No of years = 2
Compound interest
A =[tex]P(1 + \frac{r}{n} )^n*t[/tex]
A = 3600(1 + 0.352/1) ^1*1= $3726.72
Interest earned = 3726.72 - 3600= $126.72
Tax = 40% of the interest earned= [tex]\frac{40}{100}*126.72[/tex] = $50.69 (This amount is deducted from interest )
Net interest earned after 1 year = 126.72 - 50.69= $76
Balance after 1 year = $3600 + $76= $3676
Similarly for the 2nd year
Compound interest
A =[tex]P(1 + \frac{r}{n} )^n*t[/tex]
A = 3676( 1+0.0352/1)^1*1= 3676(1.0352)
= $3805.4
Interest earned = 3805.4 - 3676= $129.4
Tax = [tex]\frac{40}{100}*129.4[/tex]= $51.76
Net interest earned =129.4 - 51.76= $77.64
Net balance after 2nd year = 3676+ 77.64= $3753.64

Which of the functions below could have created this graph ?
Answer:
Step-by-step explanation:
There is parabola on the graph, so the function might be quadratic or 4th power. We have no numbers on axises, then let's analyze the answers:
(A) The graph is no parabola for this function.
(B) The parabola for " - x² " is opened downward.
(C) The parabola for this function is also opened downward.
(D) This one option is the answer. The y-intercept is (-2)
According to the y-intercept and it's behavior, the function that could have created it's graph is:
D. [tex]F(x) = x^4 + 2x - 2[/tex]
This function has a negative y-intercept, that is, when [tex]x = 0[/tex], y has a negative value, which means that options A and B are incorrect.
The function also points upwards, which means that the leading coefficient, that is, the multiplier of the value of x with the highest exponent is positive, hence option C is incorrect.
Thus, the function is:
D. [tex]F(x) = x^4 + 2x - 2[/tex]
