Answer
Input= 5
Output= 120
Step-by-step explanation:
The input goes up by 1, so m=5
The output shows how many hours there are in that many days so blank=120
First you would solve 4x=28. Divide both sides by 4 and you'll get x= 7. Then you plug in the 7 in replacement for the x in the equation, 29-5x and you'll get as an answer -6!!
Answer:
60,000 people
Step-by-step explanation:
Given the number of people y (in thousands) who bought a cell phone without a camera can be estimated by the equation y=-30x+240,
x is the number of years after 2014
<u>We can find the number of people that bought the cell phone in 2020. </u><u>In year 2020, that will be after 6years</u>
Substitute x = 6 into the expression
y=-30x+240
y=-30(6)+240,=
y = -180 + 240
y = 60
Since y is in thousands, hence the the number of people that have bought the cell phone by 2020 is 60,000 people
