How do you determine the coordinates of a point after a reflection in the y-axis?
The rule for reflecting over the Y axis is to negate the value of the x-coordinate of each point, but leave the -value the same.
A reflection is a mirror image of the shape. An image will reflect through a line, known as the line of reflection.
When a point is reflected across the Y-axis, the Y-coordinates remain the same, and the X-coordinates are transformed into their opposite signs.
Therefore, the reflection of the point (x, y) across the Y-axis is (-x, y).
A reflection of a point, a line, in the Y axis reflects the image over the Y axis to create a mirror image. In this way, the Y axis would be called the axis of reflection.

Select the correct answer. What is the slope of the line represented by this equation? -3x + 8y = 12 a. B. C. D.
With the help of the given equation, we know that the required slope is (A) 3/8.
What is a slope?In math, the gradient of a line is a number that tells you how steep it is and in which direction it goes in.
The point-slope form is a way of writing equations (y-y₁=m(x-x₁)) to emphasize the slope and a point on the line that isn't the y-intercept.
To highlight the same line's slope and y-intercept, you can rewrite the equation in slope-intercept form (y=mx+b).
So, we have the equation:
-3x + 8y = 12
Calculate the slope as follows:
We need to change it into a more general format.
-3x+8y=12
⇒ 8y = 3x+12
⇒ y = 3x/8+12/8
⇒ y = 3x/8+3/2
If you look at it in terms of y = mx+c, the m would be 3/8.
Therefore, with the help of the given equation, we know that the required slope is (A) 3/8.

Your answer Daryl finds a pair of pants for $17.00. If the pants are on sale for 35% off, what is the sale price of the pants?
Answer:
$11.05
Step-by-step explanation:
First, you make the percent into a decimal
35% - 0.35
Next, you multiply 17 and 0.35
17* 0.35= 5.95
Then, you subtract the discount which is $5.95 from $17
17-5.95= 11.05
So, the answer is $11.05
Hope this helps :)
Answer: $11.05
Step-by-step explanation:
First how much 35% of 17:
35% = 0.35
0.35 x 17 = 5.95
Next, subtract this discount off of the total:
17 - 5.95 = 11.05
Now adding the dollar sign makes it $11.05
You need to strengthen a 22% alchohol solution with a pure alcohol solution to obtain a 40% solution. How much pure alcohol should you add to 100 milliliters of the 22% solution?
To obtain a 40% alcohol solution from a 22% solution, you need to add 18% more alcohol.
How to find this?
100 ml of 22% alcohol solution contains 22 ml of pure alcohol and 78 ml of other ingredients.
Therefore, to obtain a 40% solution, you need 40 ml of pure alcohol in every 100 ml of solution.
So, 18 ml of pure alcohol should be added to 100 ml of 22% solution to obtain 40% solution.
Another way to calculate this is:
You can calculate the amount of pure alcohol you need to add by multiplying the initial volume of the solution (100ml) by the percentage increase in alcohol content (18%) .
100ml * 18% = 18ml
So you would need to add 18ml of pure alcohol to 100ml of 22% alcohol solution to obtain a 40% alcohol solution.

So the possible values of (z+1/z) are 6 and 0 for z=5 and z=-1 respectively.
Define Algebric expression.An algebraic expression in mathematics is an expression created using variables, constant algebraic numbers, and algebraic operations. A good example of an algebraic expression is 3x2 2xy + c.
What is variables and constants ?A constant has a fixed value and does not vary over time. For instance, the size of a shoe, a piece of clothing, or any other article of clothing will never alter. x+y = 8 is an algebraic equation, and 8 is a constant that cannot be altered. Variables are concepts that change or fluctuate throughout time.
We can start by multiplying both sides of the equation by (z+1/z) to get:
(z-1/z)(z+1/z) = 6(z+1/z)
This simplifies to:
z^2 - 1 = 6z + 6
We can then solve for z by isolating it on one side of the equation.
z^2 - 6z - 5 = 0
(z-5)(z+1) = 0
So the solutions to this equation are z = 5 and z = -1
Now we can substitute the value of z back into the original expression to find the value of (z+1/z)
For z = 5, (z+1/z) = (5+1/5) = 6
For z = -1, (z+1/z) = (-1+1/(-1)) = 0
So the possible values of (z+1/z) are 6 and 0.

What is GCF(greatest common factor)?
The GCF of a, b is the largest positive number that divides both a and b without a remainder
Prime factors of a number are the prime numbers that when multiplied together result in the number
Prime factors of 24
24 = 2 x 12
12 = 3 x 4

A hobby club runs remote-controlled boats in a tank that is shaped as shown. What volume of water can

The total volume of the tank is 400π + 78.72 cubic metres. To the nearest cubic meter, it is approximately 400π + 79 cubic metres.
What is the volume of a cylinder?
The volume of a cylinder is the amount of space inside the cylinder. It can be calculated by multiplying the area of the base by the height of the cylinder. The formula for the volume of a cylinder is V = πr²h, where r is the radius of the base of the cylinder and h is the height.
The tank is shown as a cylinder with a rectangular prism on top. To find the volume of water the tank can hold, we will need to find the volume of the cylinder and the rectangular prism separately, and then add them together.
The cylinder has a radius of 5 metres and a height of 8 metres. The volume of a cylinder is given by the formula V = πr²h, where r is the radius and h is the height. So the volume of the cylinder is V = π(5²)(8) = 400π cubic metres.
The rectangular prism has a length of 4.2 metres, a width of 2.2 metres and a height of 8 metres. The volume of a rectangular prism is given by the formula V = lwh, where l is the length, w is the width and h is the height. So the volume of the rectangular prism is V = (4.2)(2.2)(8) = 78.72 cubic metres.
So the total volume of the tank is 400π + 78.72 cubic metres. To the nearest cubic meter, it is approximately 400π + 79 cubic metres.
