Answer:
-3<y<=3 or B
Step-by-step explanation:
first we find the smallest y value which is -3
then we find the largest y vlaue which is three
so since there is an open circle at negative three we do not include it while at three we do.
so the answer would be -3<x<=3
if my answer helps please mark as brainliest.
A: From the graph, car B was traveling faster.
Because the line of car B is more steep than the line of car A.
B:
The lines cross at (2,80), this means that the two cars were traveling at the same distance (80 miles) at the same time (2 hours).
C:
Since the line passes through the points (0,0) and (2,80)
So the unit rate or slope is 40 mph.
The distance which car A traveled in the first four hours = 4x40= 160 mph
Answer:
The expression that represents the population of elk is:
. It'll take 6 years for the population to reach 1,458 individuals.
Step-by-step explanation:
Since the number of elks triples every year and starts at
, then after the first year the population will be:

While on the second year, it'll be:

On the third year:

And so on, therefore the expression that describes the population of elk as the years passes is:

If we want to know the number of years until the population reach 1,458 elk, we need to apply this value to the left side of the equation and solve for t.

The population will reach 1,458 elk in 6 years.
There are 3 girls .
9 students , 3 boys & 3 girls + another 3 boys because there are 3 more than girls so there are only 3 girls since you can't exceed 9 .
