Answer:
11x^2+2
Step-by-step explanation:
you put the 9x^2 beside 2x^2 because they are both x^2 then the 2 will stay the same
Remember that cos is just a translation of sin and vice versa.
So:
Sin(x) = Cos(90 - x)
Cos(x) = Sin(90 - x)
Therefore, to answer your question:
Cos(19) = Sin(90 - 19)
= Sin(71)
Answer:
y=x+4
Step-by-step explanation:
Answer:
x=1
Step-by-step explanation:
-4+7x=3 add 4 to both sides
7x=7 divide 7 on both sides
x=1
