Graph the following points on the graphing calculator:
Nimfa-mama [501]
Brainly says you need the following points

- The pattern is min-zero-max-zero-min, which is the pattern for a cosine function of the form y = acos(x) + k, but is reflected over the x-axis (so a < 0).
- The amplitude is |a|, so a = –1 and |a| = 1.
- The midline is exactly between the max and the min, y = (6 + 8)/2 = 7, so k = 7.
- The equation is y = –cos(x) + 7.

Rashawn read 25 pages of his book each day until he finished the book. His book was 400 pages long.
Katyanochek1 [597]

The first thing we are going to do for this case is define variables.

We have then:

x: number of days

y: number of pages remaining.

We write the linear equation that models the problem:

y = -25x + 400

The intersection with the vertical axis is:

We evaluate x = 0:

y = -25 (0) + 400\\y = 0 + 400\\y = 400

We get the point:

(x, y) = (0, 400)

The intersection with the horizontal axis is:

We evaluate y = 0:

0 = -25x + 400\\25x = 400

x = \frac{400}{25}\\x = 16

We get the point:

(x, y) = (16, 0)

Answer:

The graph is:

y = -25x + 400
