Answer:
- 2x + y
- 3 x - 2y
- -1
2(3 x - 2y) = -6x + 4y
2x + y + -6x + 4y + -1 = -4x + 5y -1

- 3) you will find the solution
Answer:
23.6°
Step-by-step explanation:
In this question we have to use some trigonometry to work out angle XVW. Since we are working out angles all of the trigonometric functions will have to be to the ⁻¹. The first thing we need to identify is will formula will we use out of the following:
Sin⁻¹ = Opposite ÷ Hypotenuse
Tan⁻¹ = Opposite ÷ Adjacent
Cos⁻¹ = Adjacent ÷ Hypotenuse
-------------------------------------------------------------------------------------------------------
10 = Hypotenuse
4 = Opposite
-------------------------------------------------------------------------------------------------------
We know which formula to use because the length won't be in the triangle for example we will be using the Sin triangle because we don't have an adjacent. If we don't have an adjacent then the other formula's won't work.
Now we substitute in the values to find the value of angle XVW
Sin⁻¹ = Opposite ÷ Hypotenuse
Sin⁻¹ = 4 ÷ 10
The value of angle XVW is 23.57817848
Transformation which can be used for mapping of one triangle to another are;
- Only translation
- Rotation then dilation.
What does mapping mean in geometry?
- Any method that is outlined for assigning a specific object from one (or the same) set to each object in another is known as mapping.
- Any set, including all whole integers, all the points on a line, or all the objects inside a circle, can be mapped.
We need to map one triangle to another ;
Hence, for mapping of one triangle to another,
The transformation which can be used from the given options are;
- Only translation
- Rotation then dilation

You solve for the domain by setting the radicand less than or equal to 0 and solving for x. Dividing by a -x, we switch the sign so we have that the domain is less than or equal to 0, or all negative numbers. We know that it breaks every law in math to have a negative radicand with an even index, so if the domain is all negative values of x, taking a negative of a negative gives us a positive. The negative sign OUTSIDE the radical means you are flipping the graph upside down. So instead of having a range of y is greater than or equal to 0 as does the parent graph, you have flipped it upside down so it heads more negative in regards to the range. Therefore, the domain and the range both have the same sign, thee last choice from above.
