Answer:
f(x) = 4/7x + 20/7
Step-by-step explanation:
If we were to graph this function, we would see that the two points would be, (-5, 0), and (2, 4). First, we have to find the slope, which is equal to:
<u>(first y-coordinate - the second y coordinate)</u>
(first x-coordinate - second x coordinate)
= <u>(0 - 4)</u>
(-5 - 2)
= -4/-7 = 4/7. now, we multiple -5 by 4/7 and get -20/7. we have to add 20/7.
Thus, the answer is f(x) = 4/7x + 20/7
22x
(11x) (2)
this is supposed to look like a factor tree where 11x and 2x are circled :)
Answer:
Cluster Sample
Step-by-step explanation:
According to ThoughtCo., "A cluster sample involves using a simple random sample of evident groups that the population contains." Since only the first students that enter the cafeteria are surveyed, not all grade levels are included. Since most schools do lunch by grade, only a certain grade would get to have a say, so there could be some bias.
(Edit: Looking back on this it might could be a convenience sample but it depends on what the answer choices are)
Let's first calculate the inner functions, then fill in in the outer one:
g(-1) = 1/-1 = -1.
f(-1) = (-1)^2 + 9(-1) = 1 - 9 = -8
And then
f(1/2) = (1/2)^2 + 9(1/2) = 1/4 + 9/2 = 19/4
g(19/4) = 4/19
Answer:
0
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(5-5)/(3-6)
m=0/-3
m=0
