Answer The line two origins are 6 and 5.1
Step-by-step explanation:
Hope this helps ^^
Answer:
(3,4)
Step-by-step explanation:
first you're going to solve the equation -2x
your equation should now be: 
next you're going to substitute the given value of -2x into the equation 
so your equation should now be: 
next you're going to solve the equation for y
equation should now be: y=4
than you're going to substitute the given value of y into the equation
×
then you're going to solve the equation for x
your equation should now be: x=3
then the possible solution of the system is the order pair: (x,y)=(3,4)
<span>4x^2 - 25
= (2x)^2 - 5^2 .................using a^2 - b^2 = (a+b)(a-b)
= (2x + 5)(2x - 5)</span>
Assuming ya meant

to slimplify, we use a variation of the pythagorean identity and a decomposition into the sin and cos
for the pythaogreaon identity

divide both sides by


since

subsitute

recall that

also that cos(x) is an even function and thus cos(-x)=cos(x)
therfore

so we get

decompose them into

and

to get

multiply by

to get

we can furthur simlify to get

the expression simplifies to tan(x)sin(x)
