Answer:
(- 2, 3 )
Step-by-step explanation:
Given the 2 equations
x + y = 1 → (1)
2y - x = 8 → (2)
Adding the 2 equations term by term will eliminate the x- term
(x - x) + (y + 2y) = (1 + 8), that is
3y = 9 ( divide both sides by 3 )
y = 3
Substitute y = 3 into either of the 2 equations and solve for y
Substituting y = 3 in (1)
x + 3 = 1 ( subtract 3 from both sides )
x = - 2
Solution is (- 2, 3 )
The number of terms in the binomial expansion of (3x-5)^9 is 10
<u>Answer:</u>
The correct answer options are C. 
and D. 
.
<u>Step-by-step explanation:</u>
The values which make the denominator equal to zero are called the excluded values.
Here, we can substitute 8 for x and check if it makes the denominator 0.
