(x-9)²=-3+x
expand
x²-18x+81=-3+x
minus x both sides and add 3
x²-19x+84=0
factor
what 2 numbers multiply to get 84 and add to get -19?
-7 and -12
(x-7)(x-12)=0
set equal to 0
x-7=0
x=7
x-12=0
x=12
the number is 7 or 12
both work
10 + x*12 = 12x+10
since the left side can be re-written as 12x+10 this does equal the right side
so any real number ( any value of x ) will work
Answer:
55.5%
Step-by-step explanation:
It may be useful for you to remember the formula ...
p(A or B) = p(A) + p(B) - p(A and B)
Using the given scenario, we can find ...
p(C or M) = p(C) + p(M) - p(C and M)
= 35.1% + 37.7% - 17.3% = 55.5% . . . . p(passing at least one course)
Answer:
After 4 more days
Step-by-step explanation:
