Equate whats inside (arguments) with base period of sine function
and solve for x to get period,
So the period of the graph of the given function is precisely 2.
Hope this helps :)
10y + 7x = 29 -5y - 9x = 2 i need to find the x and y PLS PLS PLS HELP

Hello!
10y + 7x = 29
-5y - 9x = 2
In this system, it would be easiest to eliminate y. Eliminate y by multiplying the bottom equation by 2:
10y + 7x = 29
2(-5y - 9x = 2)
Add the equations:
10y + 7x = 29
-10y - 18x = 4
--------------------
0y - 11x = 33
-11x = 33
-11x/(-11) = 33/(-11)
x = -3
Plug in the value of x into an equation to solve for y:
10y + 7(-3) = 29
10y - 21 = 29
10y = 50
y = 5.
