X ≥ 20
x = total number of minutes read
20 = minimum amount of minutes read

Giant
Step-by-step explanation:
Giant: .30c a can
Safeway: .33c a can
To figure out where each crosses the x and y axis simply plug in 0 for y and x respectively.
x intercept is where y = 0
y intercept is where x = 0
a) x intercept
ax + b(0) = c
c = ax
x = c/a so the x intercept is (c/a, 0)
y intercept
a(0) + by = c
0 + by = c
y = c/b, so the y intercept is (0,c/b)
Jus repeat the process for part b
b) x intercept
ax - 0 = c
x = c/a, so the x intercept is the same, (c/a , 0)
y intercept
0 - by = c
y = -c/b, so the y intercept is different from before (0, -c/b)
Answer:
f(-1) = -28 f(2) = 56
Step-by-step explanation:
f(-1) = 4 * 7(-1)
f(-1) =4* -7
f(-1) = -28
f(2) =4 * 7(2)
f(2) =4* 14
f(2) = 56
Answer:
At school, the maximum number of students that can be in a class room is 22. There are 25 students signed up for the geometry class.
Therefore, there are (25-22)=3 extra students.
Hence, no more students can join the class.
