if P = (4,2), Find: Rx=3 (P). Pls help!!
The coordinates of the reflected point P' will be (4, -3).
When a point is reflected over the x-axis, its y-coordinate changes sign.
In this case, the point P has coordinates (4,3).
To reflect it over the line x=3, we need to keep its x-coordinate the same and change its y-coordinate to its opposite.
So, the x-coordinate of the reflected point will still be 4, but the y-coordinate will become -3.
Therefore, the coordinates of the reflected point P will be (4, -3).

The ratio of red pens to blue pens in maxs drawer is 4 to 5 how many red pens and how many blue pens are there in the drawer if there are 342 pens altogether? HELP PLEASE
There are 152 red pens and 190 blue pens in Max's drawer, given that there are a total of 342 pens altogether.
Let's solve the problem step by step:
Identify the given information:
The ratio of red pens to blue pens is 4 to 5.
There are a total of 342 pens in the drawer.
Set up the ratio equation:
Let's assume the number of red pens is 4x, and the number of blue pens is 5x.
Here, 'x' is a scaling factor that allows us to find the actual number of pens.
We can write the equation as: 4x + 5x = 342.
Simplify and solve the equation:
Combining like terms, we have 9x = 342.
Divide both sides of the equation by 9 to solve for 'x':
x = 342 / 9 = 38.
Calculate the number of red pens and blue pens:
Now that we have the value of 'x', we can find the number of red and blue pens:
Number of red pens: 4x = 4 × 38 = 152.
Number of blue pens: 5x = 5 × 38 = 190.

graph each function. state the domain and range f(x)= {-x-2if x>0
9514 1404 393
Answer:
Step-by-step explanation:
For values of x less than zero, the graph of the function is a graph of the line
y = -x
Because the function is defined by this expression at x=0, there will be a solid dot at the end of the line there, at (0, 0).
__
For values of x greater than 0, the graph of the function is a graph of the line
y = -x -2
This line has the same -1 slope as before, but has a y-intercept of -2. The function is not actually defined as (0, -2), so there is an open circle at the end of the line there.
The table represents a function.

when using the some rule ,we only use two of the equal ratios at one time.That is we work with pairs of _____ sides and angle?
When applying the some rule, we only combine two equal ratios at once. Consequently, we deal with pairs of sides and angles that have equivalent ratios.
Which set of ratios form a proportion?When two ratios are equal, a percentage is formed; alternatively, two equal ratios can be said to produce a proportion. When we understand that two ratios are equal, you can write a proportion. The ratios of these two numbers are equal.
When two variables are correlated in a manner that their ratios are equal, this is known as a proportional relationship. In a proportional connection, one variable is always a constant value multiplied by the other, which is another way to think of them. The "constant of proportionality" is the term used to describe that constant. Two angles are said to be complimentary if their sum is 90 degrees. Alternatively put, two angles are said to be complimentary if they combine to make a right angle.

How does the sum work?The result or solution we obtain from adding two or more integers is known as the SUM. Addends are the figures that are combined. In the example above, the sum of the addends, 6, and 4, is 10. Below is another illustration: Thus, we may argue that 8 plus 5 equals 13, or 8 plus 5 equals 13.
Prepare: We'll find x.
Spread out the 2 initially on a left side of this equation:
2x plus 24 = 5x - 12
After that, shift all of the x terms to a left and each of the constant terms towards the right:
2x - 5x = -12 - 24

The distance between the two points is
d = √( -2-x)² + (3 -y)² OR d = √ (x+2)² + (y-3)².
What is distance between two points?Distance between two points is the length of the line segment that connects the two points in a plane.
The distance between two points is expressed as;
d = √ (X-x )² + (Y-y)²
X = -2
x = x
Y = 3
y = y
Therefore the distance between the two points is
d = √( -2-x)² + (3 -y)²
or it can also be written in this form
d = √ x-(-2)² + (y-3)²
d = √ x+2)² + (y-3)²
therefore the model of the distance between the two points can be
d = √( -2-x)² + (3 -y)² OR d = √ (x+2)² + (y-3)².

Answer:
y= 5/2x+4
Step-by-step explanation:
point slope formula is y=mx+b
here we have the slope which is what m represents so now we have
y=5/2x+b. A slope of 5/2 means that for every 2 x-values to the right, you move 5 y-values up, so if we move 2 units to the right from (-2,-1) you'll end up on (0,4), which is our y-intercept which is what b represents so now we have y=5/2x+4
Answer:
y = \(\frac{5}{2}\) x + 4
Step-by-step explanation:
I am not sure what form or the line you want, but most of the time it is the slope intercept form. There is more than one way to find this.
For the slope intercept form of the line, I need a slope and a y-intercept. They gave us the slope, we just have to find the y -intercept.
slope = \(\frac{5}{2}\)
x = -2 I am going to use the x and y from the point given to find b
y = -1
y = mx + b
-1 = \(\frac{5}{2}\) ( -2) + b
-1 = -5 + b Add 5 to both sides
4 = b
y = mx + b
y = \(\frac{5}{2}\) x+ 4

Two trains leave stations 560 miles apart at the same time and travel toward each other. One train travels at 90 miles per hour while the other travels at 110
miles per hour. How long will it take for the two trains to meet?
Do not do any rounding.
Answer: the two trains will meet in 2.8 hours
Step-by-step explanation:
Step 1
Speed of train A = 90mph
Speed of train B = 110 mph
Since both trains are travelling towards each other , their effective speed will be= 90 mph + 110mph= 200mph
Step 2
we know that Speed = distance / time
therefore Time = Distance / speed
Distance = 560 miles
Speed = 200 mph
Time = 560miles / 200mph
