Answer:
- reflected across the y-axis
- compressed by a factor of 2
Step-by-step explanation:
Replacing x by -x in f(x) causes it to be reversed horizontally, that is, reflected across the y-axis.
Replacing x by 2x in f(x) causes it to be compressed horizontally by a factor of 2.
Both of these transformations result in g(x) being a horizontally compressed horizontal reflection of f(x).

See the attachment for an example. The blue curve is g(x); the red curve is f(x).

Answer:
1080 minutes
Step-by-step explanation:
The greatest common factor (GCF) of the two times is 15 minutes, so their least common multiple is (120×135)/15 = 1080 minutes.
In that time, Kayla will have watched 9 shows, and Josh will have watched 8.
It will be 1080 minutes before they start again at the same time.

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
