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
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.
Answer:
a) £320
b) £720
c) 2 days
Step-by-step explanation:
The question is all about inputting values and finding a result or rearranging and finding a result.
a) d = 6. C = 50(6)+20 = 320
b) d = 2x7 (7 days a week) C = 50(2x7) + 20 = 720
c) C = 120 ... 120 = 50d+20
100 =50d d = 100/50 = 2
Answer:
$400 Altogether.
The main half of 4 is 2 , so I think they all collected 400 Dollars
so if it was 200 for Ben and collected 7 time than what he actually did
so 200 × 7
= $1400
Answer:

Step-by-step explanation:
The limit is:

so, you have an indeterminate result. By using the l'Hôpital's rule you have:

by replacing, and applying repeatedly you obtain:

hence, the limit of the function is -1/14
