Answer:
18
Step-by-step explanation:
Given the above table of the data set, the number of values less than or equal to 6 would be the sum of the frequencies of all values that is equal to or less than 6.
From the table above, we would add up the frequencies of the values of 6 and below, which is:
2 + 3 + 6 + 4 + 3 = 18
Answer = 18
2x+40=3x-85
2x-3x+40=3x-3x-85
-x+40=-85
-x+40-40=-85-40
-x=-125
Multiply by -1 to get positive x and for -125
(-1)(-x)=(-125)(-1)
x=125
Check answer by using substitution method
2(125)+40=3(125)-85
250+40=375-85
290=290
Answer is x=125
37/40
17+8+3+12=40
It doesn't simplify anymore
Step-by-step explanation:
If the polynomial is rational, then one of zeros is 3 + 2i.
We are also given f(x) is decreasing function, it means the leading coefficient is negative.
<u>The factors would be:</u>
- f(x) = - (x - 7)(x - (3 - 2i))(x - (3 + 2i)
or
- f(x) = - (x - 7)(x - 3+ 2i)(x - 3 - 2i)
