It's be because a coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression

A is the correct answer. A coefficient is just a number that appears in front of a variable. Please note that a number that doesn't have a variable behind it is still a coefficient since there is technically a variable behind it with a power of 0.

At the city museum, child admission is

kramer

We have a system of equations here:

Let 'a' = adult tickets and 'c' = children's tickets

5.80c + 9.00a = 1056.20

We also know that the total number of tickets (adults and children) was 149:

a + c = 149

We need only solve the system.

How do you complete problem number 4?

brilliants [131]

(I'm going to translate y' to dy/dx as it makes it easier to read for me, you could change it back if you wanted.)
$x \frac{dy}{dx} -y=0$
$\frac{dy}{dx} = \frac{y}{x}$
$\int \frac{1}{y} dy= \int \frac{1}{x} dx$ (separate the variables)
$\ln y=\ln x +c$
$\ln y = \ln kx$ (by letting c = ln k and using log laws)
$y=kx$ (raise everything to power e)
$3=k\times1 \implies k=3$ (applying boundary conditions)
Particular solution: $y=3x$
