The change rate is just to big to differ from 2-4 and M isnt the same rate as P in the problem, so the answer would be C. (hoped this helped :D
Answer:
A
Step-by-step explanation:
Rate of change of the functions is measured by their slopes.
Function M
Calculate slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, - 9) and (x₂, y₂ ) = (0, 1) ← 2 ordered pairs from the table
m = [tex]\frac{1+9}{0+2}[/tex] = [tex]\frac{10}{2}[/tex] = 5
Function P
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 7x + 9 ← is in slope- intercept form
with m = 7
Thus
Their rates of change differ by 2 → A

First answer is 14
Second answer is 25
Step-by-step explanation:
Median is the middle ( 1 2 3 4 5 the median would be 3)
You start at 2 and end at 27
List all the numbers from 2 to 27 and come from both ends until you get to the middle number(s)
In this case there are two 14 & 15
14+15=29 29÷2=14.5
Since there are no decimal answers you are left with 14
Range you take the two end numbers and subtract them (27 & 2)

The correct answer would be C. y = -10x
Step-by-step explanation: We cam eliminate the first two by common sense, that would leave us with options C, and D. The correct answer would be C, the reason it is not D is because D isn't a proportion, y = -10 is just stating that variable y equals -10, whereas, y = -10x represents a proportion.

A. The curve is a parabola with a vertex at (3,-4) and is traced from left to right for increasing values of t.
B. The curve is a parabola with a vertex at (3,-4) and is traced from right to left for increasing values of t.
C. The curve is a parabola with a vertex at (-3,4) and is traced from left to right for increasing values of t.
D. The curve is a parabola with a vertex at (-3,4) and is traced from right to left for increasing values of t.
Answers
Answer:
A. The curve is a parabola with a vertex at (3,-4) and is traced from left to right for increasing values of t.
Step-by-step explanation:
x = 3 + t
y = t² − 4
Eliminating the parameter:
t = x − 3
y = (x − 3)² − 4
This is an upwards parabola with a vertex at (3, -4).
x = 3 + t, so as t increases, x increases.
So the curve is traced from left to right.
Solve for x in the equation x2 – 3x+41 = 0
Answers
Answer:
no solution
Step-by-step explanation:
Let's solve your equation step-by-step.
x2−3x+41=0
Step 1: Subtract 41 from both sides.
x2−3x+41−41=0−41
x2−3x=−41
Step 2: The coefficient of -3x is -3. Let b=-3.
Then we need to add (b/2)^2=9/4 to both sides to complete the square.
Add 9/4 to both sides.

Each of the 17 guinea pigs needs its cage cleaned. If it takes 1 hour to clean 4 cages, how many hours will it take to clean all 17 cages? It will take hours to clean all the cages.
Answers
Answer:
Time taken to clean all 17 cages = 4.25 hours
Step-by-step explanation:
Total number of Guinea pig cage = 17
Time taken to clean 4 cage = 1 hour
So,
Time taken to clean 1 cage = [tex] \frac{1}{4} [/tex] hour = 15 minutes
Therefore,
Time taken to clean 17 cages = 17 × 15 minutes = 255 minutes
= [tex] \frac{255}{60} [/tex] hours
= 4.25 hours
Answer:
Time taken to clean all 17 cages = 4.25 hours

Which equation represents a line that passes through (2. - 1/2) and has a slope of 3?
y-2 = 3(x + 1/2)
y-3 = 2(x + 1/2)
y + 1/2 = 3(x - 2)
y + 1/ 2 = 2(x - 3)
Answers
Answer:
y + 1/2 = 3(x - 2) This matches the 3rd answer choice.
Step-by-step explanation:
Use the point-slope formula for the equation of a straight line that passes through the point (h, k) and has a slope of m:
y - k = m(x - h) becomes:
y + 1/2 = 3(x - 2) This matches the 3rd answer choice.
The equation of the line will be y + 1/2 = 3(x – 2). Then the correct option is C.
What is the equation of line?The equation of line is given as
y = mx + c
Where m is the slope and c is the y-intercept.
The slope is 3. Then the equation of line will be
y = 3x + c
If the equation is passing through (2, -1/2). Then we have
-1/2 = 3(2) + c
c = -6 - 1/2
Then the equation will be
y = 3x – 6 – 1/2
y + 1/2 = 3(x – 2)
Then the correct option is C.

Find an
explicit formula for the geometric sequence 120, 60, 30, 15, ....
Answers
Answer:
f(n) = 120 * (1/2)^n
Step-by-step explanation:
First the first number is 120, so we get y = 120, then 60/120 = 1/2
So we no the r, or constant rate is 1/2.
After that, we can finish our equation by doing
f(n) = 120 * (1/2)^n
or
y = 120*(1/2)^x
The explicit formula for the given geometric sequence is:
[tex]a_n = 120 \times 0.5^{n-1}[/tex]
We have,
To find an explicit formula for the geometric sequence 120, 60, 30, 15, ...,
we need to determine the common ratio, denoted by 'r'.
To find the common ratio, we divide any term in the sequence by its preceding term.
Let's choose the second and first terms:
r = 60 / 120 = 0.5
Now that we have the common ratio 'r', we can express the nth term of the geometric sequence using the explicit formula:
[tex]a_n = a_1 r^{n-1}[/tex]
where '[tex]a_n[/tex]' represents the nth term of the sequence, '[tex]a_1[/tex]' is the first term, 'r' is the common ratio, and 'n' is the position of the term we want to find.
Using the given sequence, '[tex]a_1[/tex]' is 120, and 'r' is 0.5.
Plugging these values into the formula, we have:
[tex]a_n = 120 \times0.5^{n-1}[/tex]
Therefore,
The explicit formula for the given geometric sequence is:
[tex]a_n = 120 \times 0.5^{n-1}[/tex]

Which graph shows y= (-5x) -4?
Answers
Answer:
Graph A
Step-by-step explanation
I look at the y-intercept first, and the y-intercept is -4, so looking at each graph you can see both A and D have y-intercepts of -4, since the line intercepts, or goes through the y-axis (the vertical line of the graph) at -4.
Then, you look at the variable that's changing, which is -5x. Since it's a negative, A is the graph that is negatively decreasing, because of its position on the graph. The line is going down, starting in the negative side.
