Answer: False

Explanation:

f(x) = 0

3(x-3)(x+3) = 0

x-3 = 0 or x+3 = 0

x = 3 or x = -3

This shows that if x is equal to either -3 or 3, then f(x) is 0.

The equation y = 8.1x models the relationship between the number of hours Alexander works, x, and the dollar amount he earns, y.

Katarina [22]

Start the graph at the <em>y</em>-intercept. At 0 hours, he will make $0, so (0, 0) is the <em>y</em>-intercept. From this point, he makes $8.10 an hour; go up 8.1 for every 1 hour you go over on the graph. The graph is attached.

the volume V of a gas at a constant temperature varies inversely with the pressure P. when the volume is 100 cubic inches the pr

fiasKO [112]

Answer:

The pressure is $20\ psi$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form $y*x=k$ or $y=k/x$

In this problem we have

$V*P=k$

where

V is the volume of a gas at a constant temperature

P is the pressure

we have

For $V=100\ in^{3}$ , $P=25\ psi$

step 1

Find the value of k

substitute the values of V and P

$100*25=k$

$k=2,500$

The equation is equal to $V*P=2,500$

step 2

Find the pressure when the volume is 125 cubic inches

For $V=125\ in^{3}$

substitute in the equation and solve for P

$125*P=2,500$

$P=2,500/125=20\ psi$
