PLZ HELP ASAP ON 3 A B AND C

viktelen [127]

A: From the graph, car B was traveling faster.

Because the line of car B is more steep than the line of car A.

B:
The lines cross at (2,80), this means that the two cars were traveling at the same distance (80 miles) at the same time (2 hours).

C:
Since the line passes through the points (0,0) and (2,80)

So the unit rate or slope is 40 mph.

The distance which car A traveled in the first four hours = 4x40= 160 mph

$f(x) = 2x + 3$

And

$g(x) = 2 \times {3}^{x} \\$

_________________________________

To find the y-intercept of any equation just need to put 0 (( zero )) instead of the x in the equation...

<h2>Let's do it....</h2>

_________________________________

In f ( x ) :

$y - intercept = f(0)$

$f(x) = 2x + 3$

$f(0) = 2(0) + 3$

$f(0) = 3$

Thus :

$y - intercept = 3$

##############################

In g ( x ) :

$y - intercept = g(0)$

$g(x) = 2 \times {3}^{x}$

$g(0) = 2 \times {3}^{0}$

$g(0) = 2 \times 1$

$g(0) = 2$

Thus :

$y - intercept = 2$

_________________________________

The positive difference in the y-intercept value of f ( x ) and g ( x ) is :

$|3 - 2| = |1| = 1$

So write this in the box : 1
