U^2 + 2 (u) (5/2) + 25/4 = (u +5/2)^2
answer is B. 25/4
Answer:
a = 7
Step-by-step explanation:
3(1 - 2a) = -3a - 18
3 - 6a = - 3a - 18
Add 18 to each side:
3 + 18 - 6a = - 3a - 18 + 18
21 - 6a = - 3a
Add 6a to each side:
21 - 6a + 6a = - 3a + 6a
21 = 3a
3a = 21
Divide each side by 3:
3a ÷ 3 = 21 ÷ 3
a = 7
1/9 because i you plug in two of the points into y2 -y1 over x2 -x1 thats what you get.
Step-by-step explanation:
So we go backwards, since we have x= 1/2 , 7
Now we have to foil to get the quadratic
We must simplify the terms
Our final result comes out to be
Step-by-step explanation:
By Remainder Theorem, f(5) = 91.
=> (5)³ - 4(5) + k = 91
=> 125 - 20 + k = 91
=> 105 + k = 91
=> k = -14.
