7 0
Replace f(x) with y
switch x and y
solve for y
replace y with f^-1

so

y=7x+2
x=7y+2
x-2=7y
(x-2)/7=y
f^-1=(x-2)/7

inverse is
f^{-1}= \frac{x-2}{7}

Answer:

8654557

Step-by-step explanation:

  1. (30 × 32076) = 962280
  2. Plug 962280 in: 60 + 9 × (962280) - 6023
  3. 9 × 962280 = 8660520
  4. Plug 8660520 in: 60 + 8660520 - 6023
  5. 60 + 8660520 = 8660580
  6. Plug 8660580 in: 8660580 - 6023
  7. 8660580 - 6023 = 8654557

I hope this helps!

faust18 [17]

Answer:

∠1 = 142°

<u>reason:</u> angles 1 and 2 are supplementary so they equal 180. 180-38 is 142

∠3 = 38°

<u>reason:</u> angles 2 and 3 are adjacent angles because they are diagonal from each other so they will equal the same measure.

∠4 = 142°

<u>reason:</u> since angle 4 is adjacent to angle 1 and is supplementary to angle 3, it has to be 142

∠5 = 38°

<u>reason:</u> since it is a transversal that means both of the intersections are the same measurements. so angle 5 is 38 since it matches up with angle 2

∠6 = 142°

<u>reason:</u> for the same reason as angle 5. angle 6 matches up with angle 1 so it has to equal 142.

∠8 = 142°

<u>reason:</u> since angle 8 is adjacent to angle 6 it has to equal 142. angle 8 is also a transverse angle to angle 4. and since angle 4 also equals 142, 8 has to also
