Answer:

y=x-3/15

Step-by-step explanation:

f(x)=15x+3/y=15x+3

f-1(x) is an inverse function, which means you gotta swap the x an the y:

x=15y+3

The goal is to get y alone, so you minus 3 on both sides to get

x-3=15y

And then divide both sides by 15 to get y alone

x-3/15=y

Denver gets 5/19 of the dog food.

natka813 [3]

Answer:

Fido have $\frac{42}{95}$ of the dog food (44.211 %), Engle have $\frac{28}{95}$ of the dog food (29.474 %) and Denver have $\frac{5}{19}$ of the dog food (26.316 %).

Step-by-step explanation:

If Denver gets $\frac{5}{19}$ of the dog food, then Engle and Fido share $\frac{14}{19}$ of the dog food. If Fido have $x$ of the dog food, then Engle have $\frac{4}{3}\cdot x$ such that:

$x + \frac{4}{3}\cdot x = \frac{14}{19}$

$\frac{5}{3}\cdot x = \frac{14}{19}$

$x = \frac{42}{95}$

Fido have $\frac{42}{95}$ of the dog food (44.211 %), Engle have $\frac{28}{95}$ of the dog food (29.474 %) and Denver have $\frac{5}{19}$ of the dog food (26.316 %).

malfutka [58]

Answer:

2 and -3

Step-by-step explanation:

because a coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g. 4 in 4x).

so in 2x-3y+5, 2 and -3 are the coefficients.
