Please answer from the question above :)
AlekseyPX

Answer:

205/6

Step-by-step explanation:

The question simply asks us to plug in 45 minutes into the given equation. In the graph, we see that y-axis is defined to be time. Therefore we set y=45 and solve for x.

45=-6/5x+86

-41=-6/5x (subtract 86 from both sides)

-41*(-5)=-6/5x*(-5) (multiply both sides by -5)

205=6x (divide both sides by 6)

205/6=x

inysia [295]

Answer:

f + g=9x^2 +x-9

The domain is all real values

Step-by-step explanation:

f(x) = x - 9

g(x) = 9 x^2

f + g=x-9+9x^2

      = 9x^2 +x-9

The domain is the values that x can take

The domain is all real values
