Answer:

x = 3

Step-by-step explanation:

Given the 2 equations

x + y = 3 → (1)

2x - y = 6 → (2)

Adding the 2 equations term by term eliminates the y- term, that is

3x = 9 ( divide both sides by 3 )

x = 3

Suppose a triangle has two sides of length 3 and 4 and that the angle between these two sides is 60 degrees . What is the length
Darya [45]

Answer:

  √13 ≈ 3.6056

Step-by-step explanation:

The Law of Cosines can be used to figure this. If the third side is "c", then it tells you ...

  c² = a² + b² - 2ab·cos(C)

  c² = 3² + 4² -2(3)(4)(cos(60°)) = 9 + 16 - 24(1/2) = 13

  c = √13 ≈ 3.6056

The length of the third side is √13, about 3.6056.

Graph f(x)=|x−2|+3 .<br><br> Use the ray tool to graph the function.
maks197457 [2]

Answer:

Answer:

The graph will be 2 units away from the origin on positive x-axis and three units upward from the origin towards y-axis.

Step-by-step explanation:

Here is a graph attached with it.

To graph \left | x-2 \right |+3 we know that positive \left | x \right | is a V shaped from the origin.

Key points:

  • To move rightward there must be a negative inside the parentheses.
  • And to move upward we must have positive b = constant.

If we have to move towards x-axis then we must have negative inside it.

And if we have to move upward in y-axis positive we must have positive constant value.

So the graph will be three units upward and two units rightward with a V-shaped ray.
