Notation f(0) means the graph crosses y-axis where x becomes zero

or simply y-intercept

f(x) = 3 - 2x

put x = 0

f(0) = 3 - 2(0)

f(0) = 3 - 0

f(0) = 3

Special name of f(0) : y-intercept

Answer:

once you have f(x) = 3-2x,

f(0) means the value of 3-2x after substituting 0 for x, giving f(0)=3.

This means the point (0,3) is on the graph of f(x). That point is on the y axis.

Since a plot of f(x) intercepts the y axis at f(0), the value of f(0) is called the y intercept.

A system of linear equations with fewer equations than unknowns is sometimes called an underdetermined system. Can such a system

elena55 [62]

Answer:

No, it cannot have a unique solution. Because there are more variables than equations, there must be at least one free variable. If the linear system is consistent and there is at least one free variable, the solution set contains infinitely many solutions. If the linear system is inconsistent, there is no solution.

Step-by-step explanation:

the questionnaire options are incomplete, however the given option is correct

We mark this option as correct because in a linear system of equations there can be more than one solution, since the components of the equations, that is, the variables are multiple, leaving free variables which generates more alternative solutions, however when there is no consistency there will be no solution

p varies jointly as q and the square of r, and p = 200 when q = 2 and r = 3. Find p when q = 5 and r= 2.

Margarita [4]

Step-by-step explanation:

If a variables varies jointly, we can just divide it by the other variables in relation to it.

For example, since p variables jointly as q and square of r, then

$\frac{p}{q {r}^{2} } = k$

where k is a constant

First, let find k. Substitute p= 200

q= 2, and r=3.

$\frac{200}{2(3) {}^{2} } = k$

$\frac{200}{18} = k$

$\frac{100}{9} = k$

Now, since we know our constant, let find p.

$\frac{p}{q {r}^{2} } = \frac{100}{9}$

Q is 5, and r is 2.

$\frac{p}{5( {2}^{2}) } = \frac{100}{9}$

$\frac{p}{20} = \frac{100}{9}$

$p = \frac{2000}{9}$
