C. 2 + (–3); –1 is the answer
The slope is 3 so the answer would be 3. Hope it helps! :)
Answer:
23h
Step-by-step explanation:
360-85= 275
he need 275$
so 12$ per hour
so he need 23h to collect the rest of the 360 $ 275
Ok this inequality tells you the number of devices you can have before the new plan costs more than the old plan. The new plan expression is $4.50x + $94m = y ( total cost). The old plan is $175m = y (total cost). You can see m (number of months) in both equations, you don't need it this time since we're going to to compare both to one month. Since they're both equal to y you can make them equal to each other. $4.50x + $94 = $175. Now you want to figure when the new plan is less than the old plan you switch the equal sign for a less than sign. $4.50x + $94 < $175; this will help you find the inequality you want. From there just use algebraic steps to find that x has to less than 18 or
x < 18.
