Answer:
The first stpe in solving this system of equations is finding either X or Y in terms of the other variable. Ex: x = 8 - y or y = 8 - x
Step-by-step explanation:
When faced with a system of equations problem, you need to find one variable at a time. To do this, you need to eliminate one of the variables from one of the equations. I used x + y = 8 because that was simplier to find one of the variables from. From there, you can substitute that in for the variabel in the secone equation.
3x - 2y = -6
3x - 2(8 - x) = -6
3x - 16 + 2x = -6
5x - 16 = -6
5x = 10
x = 2
Than you can use that and plug it back into one of the original equations to find the other variable.
x + y = 8
2 + y = 8
y = 6

Hope this helps...
Step-by-step explanation:
P stands for polynomial time. NP stands for non-deterministic polynomial time. Definitions: Polynomial time means that the complexity of the algorithm is O(n^k), where n is the size of your data (e. g. number of elements in a list to be sorted), and k is a constant.
Now, a German man named Norbert Blum has claimed to have solved the above riddle, which is properly known as the P vs NP problem.
Answer: the slope is -1/4. Hope this helps :)
Step-by-step explanation:
y=mx+b
m: slope
b: y-intercept
Answer:
Step-by-step explanation:
See attachment for graph
First, we need to take any corresponding values of x and y
Next, we calculate the slope (m)
Next, we calculate the line equation using:
Make y the subject
Hence, the line equation is:
Answer:
Using x for Θ:
(sinx - cosx)^2 - (sinx + cosx)^2
= (sin^2 x - 2sinxcosx + cos^2 x) - (sin^2 x + 2sinxcosx + cos^2 x)
= - 2 sinx cosx - 2 sinx cosx
= - 4 sinx cosx
= - 2sin(2x)
