The given coordinate pair, (10, -7) is not on the x–axis or the y–axis, but it is in Quadrant IV
What is a coordinate pair?
A coordinate pair specifies a point on the coordinate plane.
The coordinates of points on the x–axis have a y–coordinate of 0
Therefore, the coordinates of a point that is on the x–axis can be expressed as (x, 0)
Points that are on the y–axis have a x–coordinate of 0, which gives the coordinates of the points located on the y–axis as (0, y)
The coordinates of the given point is (10, -7), therefore, the point is neither on the x or y–axis, but in one of the four quadrants.
The coordinate of points in the first quadrant can be represented generally as (x, y)
Points in the second quadrant have the general form of (-x, y)
The points in the third quadrant can be expressed generally in the form (-x, -y)
The coordinates of points on the fourth quadrant are of the form, (x, -y)
The given point is (10, -7), therefore it is in the fourth quadrant or Quadrant IV

Triangle ABC has vertices A(-4, 1), B(-1, 1), and C(-1, 3) as shown. Reflect triangle ABC twice, first across the y-axis, then across the x-axis. Graph both reflections on one coordinate plane. Then rotate triangle ABC 180° about the origin. Graph the rotation.
As per the given question;
The coordinates of the original triangle ABC with vertices is ;
A(-4, 1), B(-1, 1), and C(-1, 3)
For the first reflection along y-axis, the coordinates of y will remain same and x will reverse to positive.
Y-axis reflection: A(4, 1), B(1, 1), and C(1, 3)
Now, the triangle is again reflected along x-axis.
Thus, for the first reflection along x-axis, the coordinates of x will remain same and y will reverse to positive.
x-axis reflection: A(4, -1), B(1, -1), and C(1, -3)
Rotation: The circular motion of an item around a center is referred to as rotation.
The rotation of triangle ABC 180° about the origin.
Rule for Rotation 180° (Clockwise and Counterclockwise);

The list which orders the numbers from least to greatest is π, √15, 4.1, 4. 85, √30.
To find the list which orders the numbers from smallest to largest we need to find the values of the respective numbers,
In the first list, we have the numbers √13, 2.1, 5.4, √/17, π. The value of √13 = 3.6 and the next term is 2.1. As 2.1 < 3.6, the list does not arrange numbers in increasing order.
In the second list, we have the numbers π, 3.2, 6.3, √17, √20. The value of π is 3.14 and the next terms are 3.2 and 6.3 which are more than the former. But the value of √17 is 4.1 which is less than the previous number 6.3.
In the third list,√23, 2.6, 1.3, √30, π the numbers are not arranged in increasing order as √23's value is 4.8 more than the second number.
In the fourth list, π,√15, 4.1, 4. 85, √30 the numbers are arranged in increasing order when calculated. The value of π is 3.1, of √15 is 3.8, then there are 4.1 and 4.85, and at last, is √30 whose value is 5.5.

Solve for n. −2(n − 3.5) > 15 n > −4 n < −4 n > 4 n < 4
Answer: N > -4
Step-by-step explanation:
Cuz It's Right
The solution for inequality is n < -4.
The given inequality is −2(n − 3.5) > 15
An inequality will have the sign < , > , ≥ or ≤ instead of an equality in an equation. That is, an inequality compares two quantities on either sides of the inequality sign.
We are asked to solve the inequality −2(n − 3.5) > 15. That is, to find the possible values for n.
−2(n − 3.5) > 15
Dividing throughout by 2,
-(n - 3.5) > 15/2
⇒ -n +3.5 > 7.5
Subtracting 3.5 from both sides,
⇒ -n > 7.5 - 3.5
⇒ -n > 4
Multiply -1 on both sides of the inequality and the inequality will be reversed,
⇒ n < -4 is the solution for n.
The solution is the values of n less than -4.

11.) You have $49.99 to spend for a pair of jeans. The sales tax is 7%. What is the
most the jeans can cost?
A) $46.49
B) $46.72
C) $29.41
D) $45.16
Answer:
B) $46.72
Step-by-step explanation:
Let j = cost of the jeans
j * 1.07 is the cost of the jeans with tax
j * 1.07 = 49.99
Divide each side by 1.07
j * 1.07 /1.07 = 49.99 / 1.07
j =46.72
The jeans can cost no more than 46.72
Answer:
B) $46.72
Step-by-step explanation:
The problem can be expressed as an equation you solve for "y"
y + y * 0.07 = 49.99
We factor out the "y" from the equation and we get
y * (1 + 0.07) = 49.99
Which is the same as
y * 1.07 = 49.99
We can then divide by 1.07 both sides
y = 49.99 / 1.07
Which yields
y = 46.719

A construction crew is lengthening a road. The road started with a length of 53 miles, and the crew is adding 4 miles to the road each day.
Let L represent the total length of the road (in miles), and let D represent the number of days the crew has worked.
Write an equation relating L to D. Then use this equation to find the total length of the road after the crew has worked 36 days.
Answer:
L = 4D + 53
After 36 days of work, the road will be 197 miles long.
Step-by-step explanation:
This question requests that an equation is found to represent the relationship between the length of a road and the days that the workers spend working on the road.
We are given that the road is 53 miles long prior to the work done by the construction crew. This means that this will be added in addition to what we will find.
L represents the length of the road after D days. Since the road is lengthened by 4 miles each day, this could be represented by 4 * D, or simply 4D.
Therefore, the equation we find can be written as L = 4D + 53.
Since we need to find how many miles the road will be after 36 days of work, substitute 36 days as D and solve for L:
L = 4(36) + 53
L = 144 + 53
L = 197
Therefore, the road will be 197 miles long after 36 days of construction.
Which of the following statements best describes the effect of replacing the graph of y = f(x) with the graph of y = f(x − 2)?
A) The graph of y = f(x) will shift left 2 units.
B)The graph of y = f(x) will shift right 2 units.
C) The graph of y = f(x) will shift up 2 units.
D) The graph of y = f(x) will shift down 2 units.
We have a horizontal translation of 2 units to the right, so the correct option is B.
"The graph of y = f(x) will shift right 2 units."
Which effect will have it on the graph?
For any function f(x), a horizontal translation of N units is written as:
g(x) = f(x + N)
if N > 0, the translation is to the left.
if N < 0, the translation is to the right.
In this case we have the function written as:
y = f(x - 2)
So we have N = -2, which means that we have a translation of 2 units to the right.
Then the correct option is B.

Suppose that you decide to buy a car for $27,635, including taxes and license fees. you saved $5000 for a down payment and can get a three-year car loan at 6.36%. Find the monthly payment and the total interest for the loan
the monthly payment of $ 668.75 will be paid for the loan for the car.
Total payment for the car = $ 27,635
Money for down payment = $ 5000
Interest for 3 year loan = 6.36 %
Amount on which this interest will be applied = $ 27,635 - $ 5000
Amount = $ 22,635
Interest = 6.36 % of $ 22,635
Interest = 6.36 / 100 × $ 22,635
Interest = 1440 (approx.)
Total amount of loan = $ 22,635 + $ 1440
= $ 24075
Number of months = 3 × 12 = 36 months
So, monthly payment = $ 24075 / 36
= $ 668.75
Therefore, we get that, the monthly payment of $ 668.75 will be paid for the loan for the car.

10 oranges and 20 grapefruits weigh 35 pounds total. 16 oranges and 10grapefruits weigh 23 pounds total. How much would 13 oranges and 15grapefruits weigh?A 28 poundsB 29 poundsC 30 poundsD 58 pounds20 Illuminate Education, Inc.
First, we will find the weight of each oranges and grape fruit
Let x be the unit weight of orange
Let y be the unit weight of grape fruit
If "10 oranges and 20 grapefruits weigh 35 pounds total"
Then this implies;
10x + 20 y = 35 -----------------(1)
And
If " 16 oranges and 10 grapefruits weigh 23 pounds total"
This implies;
16x + 10y = 23 ---------------------(2)
We can solve the two equations simultaneously.
Using elimination method;
we eliminate y and to do that, the y variables in the two equations must be same, Hence we can achieve that by multiply equation (1) by 10 and then multiply equation (2) by 20
100x + 200y = 350 ----------------------------(3)
320x + 200y = 460 ------------------------------(4)
subtract equation (3) from equation (4)
220x = 110
divide both-side of the equation by 220
x = 0.5
substitute x=0.5 into equation(1) and then solve for y
10(0.5) + 20y = 35
5 + 20y = 35
subtract 20 from both-side of the equation
20y = 35 - 5
20y = 30
divide both-side of the equation by 20
y = 1.5
"13 oranges and 15 grape fruits" = 13 x + 15y
substituting x = 0.5 and y= 1.5 in the above;
13(0.5) + 15(1.5)
=6.5 + 22.5
=29
Hence;
13 oranges and 15 grapefruits will weigh 29 pounds
