\frac{3.9•10^{- 4}}{7.8•10^{- 6} \\\\\\ \frac{3.9}{7.8}•10^{- 4 -(- 6)} \\\\\\\ \frac{1}{2}•10^{- 4 + 6} \\\\\\ \frac{1}{2}•10^2 \\\\\\ \frac{1}{2}•100 \\\\\\ \frac{100}{2} \\\\\\ 50

The value of x in the question
Gala2k [10]
1. 3x-10=x+70
      +10  -x
   2x=80
    x=40 

2. x+27+2x-39=180
   3x-12=180
       +12 
   3x = 180
   x = 64

3. 2x ÷ 80=5x+44
    - 2x             -44

Using f(x) = 4x + 6 with the domain of {-1,0,2}, find the range
konstantin123 [22]
The range is the output of the function, and there are many ways to find it and write it. Let's find it first by plugging in all the domain values (domain means input) into the function:
f(-1) = 4(-1)+6=-4+6=2
f(0) = 4(0)+6=0+6=6
f(2) = 4(2)+6 = 8+6=14

We have all of our values. We can either write the range as:
{2, 6, 14}

or, subtract the smallest value from the largest one:
14-2=12

So, there are those ways to write it, there are more, but I think you should stick with the first way because that's how the problem was presented to you. If you have any questions, hmu!
