Step 1. Multiply first equation with -3 and the second one with 2. You'll get:

Step 2. Add both equations together. You'll get:

, which gives x = -2
Step 3. Replace x = -2 in the first equation and calculate y.

The solution is: x=-2, y=5
Answer:
53.13
Step-by-step explanation:
To find the measure of an angle use an inverse trig function.
so you can take the inverse to find A
.
Use a calculator to calculate the value.
A = 53.13
Answer:
dy/dx at x=6 is 0.334
Step-by-step explanation:
The center difference method requires that the values of the function are given in equal intervals which is the case, and allows one to find the value for x = 6 using those of the function for x = 5.5 and for x = 6.5 as follows:

Answer:
x= 
Step-by-step explanation:
you might need a calculator to get the answer but since it is a right triangle the legs of the triangle in this case x and the
are the same length
Answer:
x = 11/2 = 5.5
Step-by-step explanation:
2x-6 = 5
2x = 11
x = 11/2 = 5.5
