How do you solve f(x) ?
Talja [164]
F (x) = 2x + 3; find f (–1)" (pronounced as "f-of-x equals 2x plus three; find f-of-negative-one"). In either notation, you do exactly the same thing: you plug –1 in for x, multiply by the 2, and then add in the 3, simplifying to get a final value of +1

Answer:

10.8

Step-by-step explanation:

By sine rule:

\frac{x}{ \sin 81 \degree}  =  \frac{7}{ \sin 40 \degree}  \\  \\ x = \frac{7 \sin 81 \degree}{ \sin 40 \degree}   \\  \\ x =  \frac{7 \times0.9876883406 }{0.6427876097}  \\  \\ x =  \frac{6.91381838}{0.6427876097}  \\  \\ x = 10.755992 \\  \\ x  \approx 10.8
