6x + 2y = 28 - Answer: y = 14 - 3x
2x - y = 8 - Answer: y = -8 + 2x
I hope that helped you! :)
Out of the three options the first one is the right answer with the given numbers <span />
Itd be 1, because the other ones aren’t possible
Answer:
d. -7/25
Step-by-step explanation:
π<θ<3π/2 in third quadrant
tanθ = 4/3
sinθ = - 4/5
cosθ = - 3/5
cos 2θ = cos²θ - sin²θ = (- 3/5)² - (- 4/5)² = 9/25 - 16/25 = - 7/25
Answer:
B.
and
Step-by-step explanation:
The expression given is:

Like terms are terms in which their variables and the power of the variables (exponents) are the same.
While it is not necessary that the coefficient of the variables are the same, the power of the variables must be the same.
In that case, the like terms in the expression given are
and
.
Note: The question says
but the option has
.
In case its actually
instead of
, then,
is also a like term and the answer will be D.
