Answer:
2x2+9x−1=x
Step 1: Subtract x from both sides.
2x2+9x−1−x=x−x
2x2+8x−1=0
Step 2: Use quadratic formula with a=2, b=8, c=-1.
x=
−b±√b2−4ac
2a
x=
−(8)±√(8)2−4(2)(−1)
2(2)
x=
−8±√72
4
x=−2+
3
2
√2 or x=−2+
−3
2
√2
Step-by-step explanation:
This is what I got but I'm not 100% positive. I checked it on a calculator and it seemed to check out.
The correct answer is A. <span>0.125
</span><span>
1/8(this is a fraction)</span>
(divide the numerator by the denominator)
1÷8 = 0.125
If you want you can Convert the number to a percentage:<span>
0.125×100=12.5%
but the question is asking for decimal form therefore the answer is </span>0.125.
I also did the quiz and this was correct
Hope this helps!! :D
Answer:
The difference of the two means is not significant, so the null hypothesis must be rejected.
Answer: We are supped to solve for y so it will be division because that's the inverse for x. so: x/4 is your answer.
Answer:
y= -2x+2
