Answer: I think the table has the greater rate of change because to find the greater rate of change we have to find the rate of change for both function. So, for this we have to find two points for both and then using the slope formula we have to solve for it.
for the first one: (4,6)(6,9)
9-6/6-4
3/2
For the second function: (4,5)(5,10)
10-5/5-4
5/1
5
so as we see that 3/2 is not greater than 5 so the function 3 has the greater one.
I don't know how to solve the first one. I am sorry but hope this helps you!

Step-by-step explanation:
On a 40 question test students gain 6 points for each correct answer and lose 0.5 points on each incorrect answer. If everyone required to give an answer to each question, what is the formulas that describes how a student's raw score, r, depends on the number of correct answers he or she provided, c?
Answers
Answer:
r=6.5c-20
Step-by-step explanation:
The raw score is given by
r=c*6-0.5(40-c)
Taking the number of correct answers as c
The incorrect answers will be 40-c
Since each incorrect answer deducts 0.5 points. Then the deducted points will be 0.5(40-c)=20-0.5c
Since correct answers, c gives 6 points each then the number of points will be 6c
Now, the raw score will be
r=6c-(20-0.5c)
Opening the brackets, the signs change hence
r=6c-20+0.5c
r=6.5c-20
The formula that describes the student's raw score based on the number of correct answers is; r = 6.5c - 20
How to solve algebra word problems?
We are told that they gain 6 points for each correct answer and lose 0.5 points for each incorrect answer. Thus, the formula for the raw score is;
The raw score is given by
r = 6c - 0.5(40 - c)
where;
c is the number of correct answers
40 - c as number of incorrect answers
We are told that each incorrect answer deducts 0.5 points.
Thus, the deducted points = 0.5(40 - c) = 20 - 0.5c
We are told that each correct answers, c gives 6 points each. Thus, the raw score will be;
r = 6c - (20 - 0.5c)
⇒ r = 6c - 20 + 0.5c
r = 6.5c - 20

Line R, because it shows a negative association
Answers
Answer:
A.)Line P, because it is closest to most data points
Step-by-step explanation:
The line of best fit is a line which best represents the data and the data points are closely related to it.
It is also known as a trend line.
The line of best fit may pass through, some , none or all of the data points.
Also if the scatter plot does not pass through all the data point then the magnitude of positive residual must be approximately equal to the magnitude of negative residual of the data points.
Hence, by looking at the scatter plot we see that all the data points lie above Line R.
Hence, the Line R will not be a line of best fit.
But all the data points lie close to the line P , hence it act as a line of best fit.

8x-3=3x+17
Subtract 3x from both sides
8x-3x-3=3x-3x+17

What is a system of equations?
Answers
Answer and Step-by-step explanation:
A system of equations is a group of equations that need to be manipulated in some way that will figure out the values of the variables.
The most common system of equations seen is a system of linear equations, which means that the degree of the variables is no more than 1. These can be solved using elimination, substitution, or even graphing, if applicable.
Hope this helps!
Answer:
A system of equations is 2 or more equations that need to be solved. When you solve a system of equations, the answer is where the equations intersect on a graph. Sometimes there is 2 solutions (equations intersect twice), 1 solution (equations intersect once), no solution (equations don't intersect), or infinite solutions ( equations are the same).
They are usually solved using substitution, elimination, or simply looking at a graph to see where the lines intersect.
Some examples:

In △ABC, angle C is a right angle and BC > AC. Select all the statements that are true.
A. m∠B > m∠A
B. sin A > sin B
C. sin A < sin B
D. cos A > cos B
E. cos A < cos B
Answers
△ABC right angle C, leg BC > leg AC. So angle A > angle B.
a=BC, b=AC, c=AB
a > b
sin A= cos B = a/c
sin B = cos A = b/c
a = c sin A = c cos B
b = c sin B = c cos A
a > b
c sin A > c sin B
sin A > sin B
c cos B > c cos A
cos B > cos A
Answer: B, E
Final answer:
In a right-angled triangle △ABC with BC > AC, it is true that m∠B > m∠A, sin A < sin B, and cos A > cos B. These correspond to choices A, C, and D.
Explanation:
In the context of triangle △ABC where angle C is a right angle and BC > AC, we can assess the truth of various statements regarding the angles and their sine and cosine values:
m∠B > m∠A: This statement is true because in a right-angled triangle the side opposite the right angle is the hypotenuse and is the largest side. Therefore, the angle opposite the longest side (BC) must be the largest acute angle, hence m∠B > m∠A.
sin A > sin B: This statement is false. Since m∠B > m∠A and sine of an angle increases with the angle's magnitude (for acute angles), it must be that sin A < sin B.
sin A < sin B: This statement is true based on the relationship of the sides and angles mentioned earlier.
cos A > cos B: This statement is true. Since m∠B > m∠A and cosine of an angle decreases as the angle's magnitude increases (for acute angles), it must be that cos A > cos B.
cos A < cos B: This statement is false for the same reason that cos A > cos B is true.
The correct statements are therefore A, C, and D.
(9 – 6i) × m = 9 – 6i
What is m?

9 + 6i
-9 + 6i
Answers
To solve for m in the equation (9 – 6i) × m = 9 – 6i, both sides are divided by (9 – 6i), yielding m = 1.
Explanation:The equation given is (9 – 6i) × m = 9 – 6i. To find the value of m, we can divide both sides of the equation by (9 – 6i). Doing so, we get:
m = (9 – 6i) / (9 – 6i) = 1.
Therefore, the value of m is 1.
triangle ABC is isosceles a= 56 degrees work out three possible values of angle B
Answers
def: -in an isosceles triangle two of its angles measure the same
- the sum of all angles in a triangle is 180°
case1: if angle a measures the same with another angle in the triangle
=>angle1=56
angle2=180-2*56=180-112=68°
from this case we extract 2 posibilities:
B=56° or B=68°
case2: if the other 2 angles beside a measure the same
angle1=angle2=(180-56)/2=62°
from this case we e extract one posibility:
B=62°
Final answer:
In an isosceles triangle ABC with angle A equal to 56 degrees, three possible values for angle B are 68 degrees if it is the vertex angle, and 56 degrees or 62 degrees if it is one of the base angles.
Explanation:
If triangle ABC is an isosceles triangle with angle A (a) equal to 56 degrees, we can work out three possible values of angle B using the properties of an isosceles triangle and the fact that the sum of angles in any triangle is 180 degrees.
Since triangle ABC is isosceles, two of its angles are equal. If angle A is one of the two equal angles, then angle B (which is the vertex angle) is given by:
B = 180° - 2AIf angle B is one of the two equal angles, then we have two cases:
B = A (the two base angles are equal)B = (180° - A) / 2 (the vertex angle is different)In the first case where angle B equals angle A (56 degrees), then the other base angle (angle C) must also be 56 degrees, and the remaining vertex angle B would be 180° - 56° - 56°, which is 68 degrees.
In the second case, where B is the vertex angle:
B = 180° - 2AB = 180° - 2(56°)B = 180° - 112°B = 68 degreesThis gives us the same value for angle B as in the first case since both result in the same configuration.
Finally, if angle B is one of the two base angles and equal to angle C, then B would be (180° - A) / 2:
B = (180° - 56°) / 2B = 124° / 2B = 62 degreesSo, three possible values for angle B are 68 degrees, 56 degrees (if B is one of the base angles), and 62 degrees (again, if B is a base angle).

We are told [tex]a-b=2[/tex] being [tex]a[/tex] and [tex]b[/tex] positive integers, hence:
[tex]a=2+b[/tex] (1)
Now we have the following expression:
[tex]\frac{4^{0.5 a}}{2^{b}}[/tex] (2)
Which can be also written as:
[tex]\frac{2^{2(0.5 a)}}{2^{b}}[/tex] (3)
Since [tex]4=2^{2}[/tex]
Then, substituting (1) in (3):
[tex]\frac{2^{2(0.5(2+b))}}{2^{b}}[/tex] (4)
Since we have exponents with the same base, we can do the following:
[tex]\frac{2^{2+b}}{2^{b}}=2^{2+b} 2^{-b}[/tex] (5)
Finally:
[tex]2^{2+b} 2^{-b}=2^{2+b-b}=2^{2}=4[/tex] (6)
Hence:
[tex]\frac{4^{0.5 a}}{2^{b}}=4[/tex]

In ΔKLM, the measure of ∠M=90°, the measure of ∠K=10°, and LM = 86 feet. Find the length of KL to the nearest tenth of a foot.
Answers
Answer:
495.3 feet
Step-by-step explanation:
delta math i got the problem wrong and it gave me the right answer
Final answer:
To find the length of KL in ΔKLM with a 90° angle at M and a 10° angle at K, we use the sine function with the given hypotenuse length of 86 feet. Calculating sin(10°) times 86 gives approximately 14.9296 feet, which rounds to 14.9 feet.
Explanation:
To find the length of KL to the nearest tenth of a foot in ΔKLM, where ∠M equals 90°, ∠K equals 10°, and LM is 86 feet, we can use trigonometry.
Since LM is the hypotenuse and we want to find KL, which is the side opposite ∠K, we will use the sine function:
sin(∠K) = opposite/hypotenusesin(10°) = KL/86 feetKL = 86 feet × sin(10°)Calculating this we get:
KL = 86 feet × 0.1736 (approximate value of sin(10°))KL ≈ 14.9296 feetKL ≈ 14.9 feet (rounded to the nearest tenth)This provides us with the length of KL in the triangle.
