Answer:
x = 4
Step-by-step explanation:
given f(x) = 11 then equate f(x) = 11 and solve for x
4x - 5 = 11 ( add 5 to both sides )
4x = 16 ( divide both sides by 4 )
x = 4 ← value of x in the domain
Answer:
f^-1 (x) = x/4
Step-by-step explanation:
Answer:
We know that the interior angles of any triangle equal 180. Therefore in the left triangle, C must equal 53 in order for the interior angles to equal 180° (65+62+53)
Since these triangles are equal they are congruent. Congruent triangles share the same angles. Therefore C is equal to G. If c is 53 then m<G is also 53. x=53
Additionally, the side lengths of congruent triangles are equal. Therefore 11 is equal to x-y
x is 53 so 53-y=11
-y=-42
y=42
x=53

According to my teacher she says its b
Answer:
Step-by-step explanation:
a) you know interest is 22 and principal is 1000 and number of months is 1
b) I = rPm
r = I/Pm
c) r = 22 / 1000(1) = 0.022 /month or 2.2% per month
or 12(0.022) = 0.264 or 26.4 % per year.
d) interest is $15, loan period is 2 weeks which occurs once during the loan, interest rate is 10% per two weeks.
P = I/rm
e) P = 15 / 0.10 = $150
Notice that there are 52 weeks/yr / 2week loan period = 26 period in a year.
This means that the APR is 0.10(26) = 2.60 or 260% annual interest rate. Pretty good return on investment if you are the lender and can keep your money lent out. Not so good if you are the borrower.
