Use the equation Sin (2x -9) = Cos (x+30) to solve for x. Remember that these are complementary angles!

1 answer:

4 0

Well, if the two angles are complementary, then that means that

(2x -9)° + (x + 30)° = 90°

$\bf 3x+21=90\implies 3x=69\implies x=\cfrac{69}{3}\implies x=23$

Where would you plot the vertex on the graph of the following absolute value equation? enter your answer as an ordered pair (x,y

makvit [3.9K]

Answer:

The absolute value vertex is (5, 10). Please check that graph is also attached for the absolute equation with vertex (5, 10).

Step-by-step explanation:

Considering the absolute value equation

$y=|x-5|+10$

To find the x coordinate of the vertex, set the inside of the absolute value $x - 5$ equal to zero.

In this case,

$x - 5=0$

$x=5$

Replace the variable x with 5 back into the equation and solve for y.

$y=|(5)-5|+10$

$y=0+10$

$y = 10$

Therefore, the absolute value vertex is (5, 10). Please check that graph is also attached for the absolute equation with vertex (5, 10).
