Answer: y=1.5
Step-by-step explanation: Isolate the variable by dividing each side by factors that don’t contain the variable.
(B), (C) And (D) are right for the equation y = 8 - x but none of those are true in the second equation.
Answer:
28
Step-by-step explanation:
The answer is x = 0.5 To get this you do 9-7 which is 2 and then do 2 divided by 4 which is 0.5
<u>Here are your fill-ins:</u>
r = 1 is a zero, so (r-1) is a factor.
r = -1 is a zero, so (r+1) is a factor.
The remainders from synthetic division are 0 each time.
See the attachment for the synthetic division numbers.
_____
The reduced quadratic is ...
... x² -6x +13 = 0
Solving by completing the square, we have ...
... (x -3)² = -4
... x = 3 ± 2i
_____
The quadratic formula would tell you ...
... x = (-(-6) ± √((-6)² -4(1)(13)))/(2·1) = (6±√-16)/2 = 3±2i
