Answer:
-7
Step-by-step explanation:
(x²+6x-16)(x-2) = x³+4x²-28x+32
x³+4x²-28x+32 = ax³+bx²+cx+d
a=1; b=4; c= -28; d= 32
-28/4 = -7

Write the equation of the line in slope-intercept form using y=mx+b
Answers
Answer:
y = 4x + 4
Step-by-step explanation:
Two points you can see on the graph are (0,4) and (-2,-4)
Now, to find the slope, use delta y/ delta x
(-4-4)/(-2-0)
(-8)/(-2) = 4
Slope is 4.
y = 4x + b
Now, to find b, we need the y-intercept, which is the point where x is 0 and the graph crosses the y-axis.
This value is 4. So, the y-intercept is 4
Substitute into your equation
y = 4x + 4
There are approximately 3,000 bass in a lake. The population grows at a rate of 2% per year. Round answers to the nearest tenth.
From Year 1 to Year 4, the average rate of change of the population was about 62.4 bass per year.
From Year 5 to Year 8, the average rate of change of the population was about 67.6 bass per year.
The rate of change increased by about _____ bass per a year.
Answers
Answer:
years 1–4: 62.4 bass per year
years 5–8: 67.6 bass per year
Step-by-step explanation:
If the population in year n is ...
p(n) = 3000·1.02^n
then the average rate of change from year 1 to year 4 is ...
(p(4) -p(1))/(4 -1) = 3000(1.02^4 -1.02^1)/3 = 1020·(1.02^3 -1) ≈ 62.4
The average rate of change for years 1–4 is 62.4 bass per year.
___
For years 5–8, the rate of change is similarly computed:
(p(8) -p(5))/(8 -5) = 3000(1.02^8 -1.02^5)/3 = 1000·1.02^5·(1.02^3 -1) ≈ 67.6
The average rate of change for years 5–8 is 67.6 bass per year.

A group of students were surveyed to find out if they like playing tennis or volleyball in PE class. The results are shown in the table:
Complete the table and answer the following questions.
a. What percentage of the total students surveyed like both
Volleyball and Tennis?
b. What is the probability that a student who does like
Volleyball does not like Tennis?
Answers
Using the probability concept, it is found that:
a) 41.67% of the total students surveyed like both Volleyball and Tennis.
b) There is a 0.1667 = 16.67% probability that a student who does like
Volleyball does not like Tennis.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
Item a:
There is a total of 70 + 50 = 120 students, and x + 20 = 70 -> x = 50 like both sports, hence:
p = 50/120 = 0.4167.
41.67% of the total students surveyed like both Volleyball and Tennis.
Item b:
60 students like voleyball, and of those, 10 do not like tennis, hence:
p = 10/60 = 0.1667 = 16.67%.
There is a 0.1667 = 16.67% probability that a student who does like
Volleyball does not like Tennis.

A line is reflected, what line is the results?
Answers
Answer:
A I think
Step-by-step explanation:
I dont really get the question so im not sure
Answer:
C.
Step-by-step explanation:
The question states that a LINE is reflected, just with this information we know that A. is incorrect because it is curved.
At first, when looking at B., it seems as though it could work, until you notice that it starts somewhere, but doesn't end, thus it is not a LINE. So, we can count B as incorrect as well.
When looking at C, it it a straight line, and has a beginning and and end, which means that so far, it is the most likely the line.
Then, we look at D. When looking at D, we can tell that it is a straight line, however, it has no beginning and no end, thus it can't be the answer.
Now, we know that C is the only possible answer for this question.
