The quadratic formula is x= -b +/- √b²-4ac / 2a

In this problem,

a=6
b=4
c=-3

Now, we can plug this into the formula:

x= -4 +/- √4²-(4)(6)(-3) / (2)(6)
x= -4 +/- √16+72 / 12
x= -4 +/- √88 /12
x= -4 +/- 2√22 /12
x= -2 +/- √22 / 6

So,

x= -2 + √22 / 6
x= -2 - √22 / 6

Molly earns a rebate each month on her movie tickets and books. She earns $0.25 for each movie ticket and $2 for each book. Last
stiv31 [10]

Answer:

8 books

Step-by-step explanation:

Earning for each ticket is $0.25 and for each book is $2

If total earning for 4 tickets and x books is $17, then the equation is:

  • 0.25*4 + 2x = 17
  • 1 + 2x = 17
  • 2x = 16
  • x = 16/2
  • x = 8

So Molly purchased 8 books

During a certain day, a worker did 77 parts. He usually does 55 parts per day. What was the percent by which he increased the us
ANTONII [103]
So, he usually does 55 only, but this one day he did 77, 77 - 55 is 22, so he did 22 more this one day.

if we take 55 to be the 100%, what is 22 off of it in percentage anyway?

\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
55&100\\
22&p
\end{array}\implies \cfrac{55}{22}=\cfrac{100}{p}\implies p=\cfrac{22\cdot 100}{55}
