1 answer:
Bear in mind that, a "solution" so-called, or a zero, or a root, is really just an x-intercept of the graph, namely, where does the graph touch the x-axis? that's a zero/root/solution/x-intercept.
now, about those two lads above, check the picture below.
notice, that, the horizontal line, by definition will never touch the x-axis, whilst the other one does, at x = 2.

3x+60=150 can be used to determine the number of days you read. Solving the equation determines that you have been reading for 30 days.
Step-by-step explanation:
Total pages = 150
Pages per days = 3
Pages left to read = 60
Let,
x be the number of days.
According to given statement;
Total pages = Pages per day*number of days + Pages left to read
Dividing both sides by 3
3x+60=150 can be used to determine the number of days you read. Solving the equation determines that you have been reading for 30 days.

Solution
f(r) = 3.14
Now we have to find the area of the circle when the radius (r) = 4.
Plug in r = 4 in f(r) to get the area of the circle.
f(4) = 3.14
f(4) = 3.14 * 4 * 4
f(4) = 3.14 *16
f(4) = 50.24
The answer is C. 50.24
