Page from ready workbook, it’s about rational numbers
Answer:
-74
Step-by-step explanation:
Graph the function. See attached picture. Between the interval where -4 > x < 0, the graph rises up to a peak and descends back down when x = 0. This means the minimum value will be where x = -4.
Substitute x = -4 into the equation.
f(-4) = (-4)^3 -3(-4)^2 - 9(-4) + 2
f(-4) = -64 -3(16) +36 + 2
f(-4) = -64 - 48 + 36 + 2
f(-4) = -74
Answer:
The correct answer is C.
Step-by-step explanation:
First, we can eliminate A and D since it is obviously only 36 months.
Note that the question asks what can be interpreted from the <em>range</em> of the graph.
The range is the number of users in thousands (per month) (as can be seen from the side title).
While B is technically correct, it wrongly interprets the range. C is the best choice.
The correct answer is C.
for the first one set 3y+y=180 and y+x=180
the second one set w+y=180, 42+x=180, y+20=180, and 87+v
