The reflection of the coordinate (-3, 4) over the y-axis is (3, 4).
Reflection of coordinatesThe Y-coordinates do not change when a point is reflected across the Y-axis. However, the X-coordinates are changed into their opposite signs.
Given the coordinates of the triangles RST as shown below;
R = (-3, 4)
S = (-1, -4)
T = (-4, -2)
If (x, y) for instance is reflected over the y-axis, the resulting coordinate will be (-x, y). Similarly, if the coordinate R (-3, 4) is reflected over the x-axis, the resulting coordinate point will be (3, 4)

The points P, Q, R, S, T, U, A and B on the number line are such that, TR = RS = SU and AP = PQ = QB. Name the rational numbers represented by P, Q, R and S.
Note that the rational numbers represented on points- P, Q, R, and S are given as follows: 7/3, 8/3, -4/3, -5/3 respectively. See the explanation below.
What is a rational number?A rational number is defined in mathematics as the proportion or fraction p/q of two integers, a numerator p, and a non-zero denominator q. 3/7, for example, is a rational number, as is every integer.
For the solution above:
Each section in between two numbers is broken into three sections.
Thus, we have a = (6/3), P = (7/3), Q = (8/3) and B = (9/3)
In the same way,
T = = -3/3,
R = -4/3
S = -5/3 and
U = -6/3
Therefore, the rational numbers represented - P, Q, R, and S are given as follows: 7/3, 8/3, -4/3, -5/3.

Yuto left his house at 10 a.m. to go for a bike ride. By the time Yuto’s sister Riko left their house, Yuto was already 5.25 miles along the path they both took. If Yuto’s average speed was 0.25 miles per minute and Riko’s average speed was 0.35 miles per minute, over what time period in minutes, t, starting from when Riko left the house, will Riko be behind her brother?
The time period that Riko would be behind is going to be the inequality 0 ≤ t < 52.5 minutes .
How to solve the inequalityHow to solve for the period t that Riko would be behind her brother
The question says that at the time he left the house, Yuto was 5.25 miles ahead of her.
The amount of miles that she would have gained on Yuto within this period would be 0.35 - 0.25 = 0.1 miles on Yuto
Therefore at every mile she would be closing in on 0.1 miles
For her to close the gap that is made here, it would be 5.25 / 0.1
= 52.5 minutes
Therefore we would say that The time that Riko would be behind is going to be 0 ≤ t < 52.5 minutes .

Is our divisor a whole number? 13.5 divided by 0.03 [Powers of 10 - What should you multiply by to get a whole number?]
No, the divisor 0.03 is not a whole number, we should multiply by 10² to get a divisor a whole number.
As given in the question,
Given expression:
13.5 divided by 0.03
Dividend of the given expression = 13.5
Divisor of the given expression = 0.03
No, the divisor 0.03 is not a whole number.
Power of 10 which should be multiply by 0.03 to get a whole number
0.03 = 3 /100
(3/100) should get multiply by 100
100 = 10²
0.03 ×10² =3 whole number
Therefore, the divisor 0.03 is not a whole number, we should multiply by 10² to get a divisor a whole number.

I only need the answer for 18 please
The equation of the line parallel to 2x + 3y = 18 and passing through point ( 6, 4) is 3y + 2x = 24.
Consider the line 2x + 3y = 18,
The equation of the line in slope-intercept form can be written in the form y = mx + b, where m is the slope of the line.
Therefore,
2x + 3y = 18
Subtracting 2x from each side
2x + 3y - 2x = 18 - 2x
3y = 18 - 2x
Dividing each side by 3.
y = 6 - ( 2/3 )x
y = - (2/3)x + 6
Hence, the slope of the line is - 2/3.
Now, if two lines are parallel then they have the same slope.
Now, the line parallel to 2x + 3y = 18 passes through ( 6,4).
Therefore, using the slope-intercept form:
y = mx + b
4 = ( -2/3 ) × 6 + b
4 = - 4 + b
b = 8
Therefore, the equation of the line parallel to 2x + 3y = 18 is:
y = ( - 2/3 )x + 8
3y = - 2x + 24
3y + 2x = 24

What is mathematical operation?An operation, often known as a "operand" or "argument," is the function in mathematics that converts zero or more input values into a clearly defined output value. The operation's arity is determined by number of operands.
Binary operations (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive inverse and multiplicative inverse, are operations that are most frequently studied. A constant is operation with arity zero, often known as a nullary operation. An example of operation of arity 3, sometimes known as a ternary operation, is the mixed product.

Hi, could someone please help me with this thanks I don’t understand how they got this
First, we need to know the units they used. For every hectare, there are 2.47105 acres.
Next, we can set up a proportion to solve.
[tex]\displaystyle \frac{\text{\$8,963}}{1 \;acre} =\frac{\text{\$x}}{2.47105 \;acres}[/tex]
Now, we will cross-multiply:
$8,963 * 2.47105 = x
x ≈ $22,148
I was $10 from the answer they ended up with, so I most likely used a different conversion unit factor than they did. However, the steps are still the same.
0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20 find the interquartile range
The interquartile range for the given set of numbers {0,2,4,6,8,10,12,14,16,18,20} is 12 .
The interquartile range(IQR) can be calculated by the formula
IQR = Q₃ - Q₁
where Q₃ is the third quartile
and Q₁ is the first quartile
In the question,
the set of numbers is ascending order is given as
0,2,4,6,8,10,12,14,16,18,20
Q₃ means median of the upper half
the upper half of the data is 12,14,16,18,20
the median of the upper half is 16 ,
So Q₃ = 16 .
Q₁ means median of the lower half
the lower half of the data is 0,2,4,6,8
the median of the lower half is 4 ,
So Q₁ = 4 .
Hence , the IQR = Q₃ - Q₁ = 16-4 = 12 .
So, IQR for given set of numbers is 12.
Therefore , the interquartile range for {0,2,4,6,8,10,12,14,16,18,20} is 12 .

What does multiplication mean in math?
Multiplication in mathematics is a technique for determining the sum of two or more numbers. It is a fundamental operation in mathematics that we perform frequently.When a single number is added up several times, it is said to be multiplied. A 5 multiplied by a 4 results in 20 (5 + 5 + 5 + 5). The number five was taken, and four additions were made. Due to this, multiplication is occasionally referred to as "times."5×395=5×(400×-5)
