PLLSSS REALLY URGENT If g(x)=3x+4, determine n that g(-3)=g^-1(n).

Mathematics
1 answer:
grigory [225]2 years ago
5 0

Answer:

we have:

g(-3) = 3.(-3) + 4 = -5

g {}^{ - 1} (n) =  \frac{1}{3n + 4}

because

g( - 3) = g {}^{ - 1} (n)

=>

- 5 =  \frac{1}{3n + 4} \\  \\  <  =  >  - 5(3n + 4) = 1 \\  \\  <  =  >  - 15n - 20 = 1 \\  \\  <  =  > n =  \frac{ - 21}{15}  \\  \\  <  =  > n =  \frac{ - 7}{5}

An angle measures 81.2º more than the measure of its supplementary angle. What is the
Usimov [2.4K]

Step-by-step explanation:

Supplementary angles add up to 180 degrees

Let x represent the smaller angle:

x + (x + 81.2) = 180

2x + 81.2 = 180

2x = 98.8

x = 49.4 degrees

therefore:

smaller angle = 49.4 degrees

larger angle = 49.4 + 81.2

= 130.86 degrees
