145, you subtract the total number with how many you sold
523-378=145
The first equation equals 13
The second one equals 12
to help you discover the answer better I really think the second one
Answer:
I believe its 42
Step-by-step explanation:
i did n =14 i think and then multiplied it by 3 but i really dont exactly know
We need to write the linear equation that is satisfied by (20,13) and (30,18).
$18 - $13 $5
The slope is m = --------------- = -------- = $0.50/mile
30 - 20 10
We need to find the y-intercept of this function. To do that, start with the slope-intercept form y = mx + b
and subst. the y and x values from one of the two given points. Suppose we choose (20,$13):
$13 = ($0.50/mile)(20 miles) + b
Then $13 = $10 + b, and b = $3.
There's an up-front charge of $3 just to step into the taxi.
The equation in question is y = ($0.50/mile)x + $3.00 (answer)
