Idk what linear combination is but you can solve this way:
3x+y=4
-2x-y=-5
x=-1
3(-1)+y=4
-3+y=4
y=7
So x=-1 and y=7
<span>Differentiating :
y' = 1 + sec^2(x),
</span><span>
cosπ=−1</span><span>
plug in pi = -1 ,for x:
1 + sec^2(pi) = 1 + (-1)^2
= 2</span>
Answer:When you are given a problem, the two sides are equal, so they are equally weighted. As long as you do the same thing on both sides, they remain the same weight. The only way that one side can become "more weight" on a side is if you make a math mistake, and thus the answer would not satisfy the original equation
Step-by-step explanation:looked it up... have a good day!
Answer:
This is not my answer, it was done by another expert in Brainly.
We are given:
csc (0) * sin (0)
This is to be simplified using trigonometric identities:
csc (x) = 1/sin(x)
so, csc (0) = 1/sin(0)
then,
1/sin(0) * sin (0), the result will be sin(0) / sin (0) which is equal to 1.
Therefore, the answer is 1.
