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?
Answers
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.

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]
Answers
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.

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.
Answers
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.

At an electronics store, a smart phone is on sale for 35% off the original price of $679. If you use the store credit card, you can receive an additional 15% off the sale price. What is the final price of the smart phone if you use the store credit car
Answers
Answer:
The final price of the smart phone if you use the store credit card is $339.5
Step-by-step explanation:
Given;
original price of the smart phone = $679
initial discount = 35%
additional discount if you use the store credit card = 15%
total discount of the smart phone if you use the store credit card
= 35% + 15% = 50%
The final price of the smart phone, if you use the store credit card is given as;
P = 0.5 X $679
P = $339.5

Step 1: Define equation
4(x - 1) = 2(6 - 2x)

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?
Answers
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.
Select the equation which represents the graph.

what is the solution set of the above question ?
Answers
Answer:
The solution set is { } or ∅ ⇒ empty set
Step-by-step explanation:
∵ 2x + 10 < 10
→ Subtract 10 from the two sides of the inequality
∵ 2x + 10 - 10 < 10 - 10
∴ 2x < 0
→ Divide both sides by 2
∴ [tex]\frac{2x}{2}[/tex] < [tex]\frac{0}{2}[/tex]
∴ x < 0
∴ The solutions are all the negative numbers
∵ x ∈ N
∵ N is the set of Natural numbers
→ The natural numbers start at 1 and include all positive whole numbers
∴ N = {1, 2, 3, 4, 5, ..............}
∵ N does not contain any negative numbers
∴ The solution set is an empty set ⇒ ∅
∴ The solution set is { } or ∅
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)
Answers
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

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
Answers
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
A = $15

1667
16670
Step-by-step explanation:
Any number to the zeroth power is 1, so the first one is 1 x 16.67, which equals to 16.67
10 to the first power is just 10, so multiply 10 x 16.67 for the second one. This equals 166.7
10 to the second power is 10 x 10 or 100, so multiply 100 x 16.67, which is 1667.
10 to the third power is 10 x 10 x 10 or 1000, so multiply 1000 x 16.67, which is 16670.
Basically, for each one, starting with 10 to the first power, move the decimal to the right one place.
