Y=5x+30

X is the days

And so by plugging in x you get

y=5(5)+30
y=25+30
y=55

And so by day 5 she's running 55 minutes

Are the functions inverse of each other?<br><br> f(x)=5x^2+3, g(x)sqrt x-3/5

luda_lava [24]

Answer:

No.

Step-by-step explanation:

Plugging in g(x) into f(x), you don't get x. g(x) would need to be = $\sqrt{x\frac{-3}{5} }$

F(x)=-2(x-3)(x+5) convert quadratic functions to standard form

jasenka [17]

Answer:

The answer is: f(x) = -2x^2 - 4x + 30

Step-by-step explanation:

Given:

f(x)=-2(x-3)(x+5)

Solve (x-3)(x+5) first, then multiply by -2:

f(x) = -2[(x - 3)(x + 5)]

f(x) = -2[x^2 -3x + 5x - 15]

f(x) = -2[x^2 + 2x - 15]

f(x) = -2x^2 - 4x + 30
