Answer: the question can only be simplified to -8z-12 because there is no equal sign.
Step-by-step explanation:
(4z - 12) - 12z
-8z-12
Answer:
a > 12
Step-by-step explanation:
To ride the go karts you need to be OVER 12 years old. We are going to use < and > because you can't be 12 and younger. The hint is OVER because this essentially means that the variable a HAS to be bigger than 12. Thus is why the ineuality is a > 12.
Best of Luck!
Answer: B
<u>Step-by-step explanation:</u>
In order to get the best representative sample, you should choose the widest range of students, which is from a random sample of all students.
(A) Choosing from only the 6th graders, eliminates the choices the other grade-level students would choose.
(C) Choosing only from students who participate in after-school activities, eliminates the choices the other students would choose.
(D) Chhosing only from students not participating in the fundraiser is silly since you want to know what the students participating in the fundraiser would choose.
The only possible option is B - students from all grades, regardless of whether or not they participate in after-school activities.
B. triangle and triangular prism
Step-by-step explanation: Given that the graph shows the side view of a water slide with dimensions in feet.
We are to find the rate of change between the points (0, ?) and (?, 40).
From the graph, we note that
the y co-ordinate for the x co-ordinate 0 is 80 and the x co-ordinate for the y co-ordinate 40 is 5.
So, the given two points are (0, 80) and (5, 40).
The rate of change for a function f(x) between the points (a, b) and (c, d) is given by
Therefore, the rate of change for the given function between the points (0, 80) and (5, 40) is
Thus, the required rate of change is -8.
