Answer:
First you have to plot Bart's Garage's fee. Bart's equation is y = 30x + 20, so you would need to plot the points (0, 20) and (1, 50).
Lisa's base fee is the same, so her equation would have a + 20 at the end of it, but her hourly fee is higher. Therefore her hourly fee would be higher than 30. Her equation could be anything above 30, y = 50x +20 would work. The points for that graph are (0, 20) and (1, 70).
Answer:
$3,274
Step-by-step explanation:
Answer:
40 because I had the same exact problem and I got an A+
So you've gotta have a variable representing the number of seconds between the time when you see lightning and the time when you hear thunder. I'm going to use <em>x.
</em>So equation:
<em /><em>x</em>/5=2
Solving:
you have to multiply both sides by five, so it becomes:
<em>x</em> = 10
so it's 10 seconds!
This is what it looks like. It opens to the right.
