Hi!
The rate of change is also known as slope.
HOW TO SOLVE:
Way 1. ) If you are given an equation in y = mx + b form, m is the rate of change, or slope.
Way 2.) If you are given two or more points, you can take those and use the equation \(\frac{y_{1}-_{2} }{x_{1}- x_{2} }\)
---
1.) using #1 from above, 29/5 is the rate of change
2.) using #2 from above, we can solve using two points; (2, 12) & (4, 17):
\(\frac{17-12}{4-2} = \frac{5}{2}\)
3.) using #2 from above, we can solve using two points; (10, 57) & (20, 112):
\(\frac{112-57}{20-10} = \frac{55}{10} =\frac{11}{2}\)
4.) using #1 from above, we want to get it into y = mx + b form:
2y - 12x = 36
add 12x to both sides
2y = 12x + 36
divide both sides by 2
y = 6x + 18
now we can see that 6 is the rate of change
5.) using #2 from above, we can solve using two points; (2, 9) & (6, 19):
\(\frac{19-9}{6-2} = \frac{10}{3}\)
6.) using #2 from above, we can solve using two points; (0, -3) & (2, 2.5):
\(\frac{2.5 + 3}{2-0} = \frac{5.5}{2} =\frac{11}{4}\)
7.) using #2 from above, we can solve using two points; (4, 14.8) & (8, 29.6):
\(\frac{29.6-14.8}{8-4} =\frac{14.8}{4} =\frac{37}{10}\)
Hope this helps! Let me know if you need any other help! :0)

If a value of 80.4° is added to the data, how does the range change?
The range decreases to 46°.
The range stays 48°.
The range stays 49°.
The range increases to 50°.
Answers
Answer:
The Range Stays 48°.
Step-by-step explanation:\
Since the value 80.4° is not the highest and not the lowest value on the list, it does not change the range.
Hope this helps!
Answer: B. The range stays 48
Step-by-step explanation:
The largest answer is 105 and the smallest answer is 57. The range is the range of numbers from smallest to largest so to find the range you subtract the largest and the smallest
Range = 105 - 57
Range = 48
The range will not change because if you put 80.4 in there, it's not the largest or smallest so it does not affect the range.
So answer is B. The range stays 48

Answer: d = ³⁄₂
Steps: -½d + ⅝ = ⅜d - ¹¹⁄₁₆
Subtract ⅝ from both sides: -½d + ⅝ - ⅝ = ⅜d - ¹¹⁄₁₆ - ⅝
Simplify: -½d = -²¹⁄₁₆ + ⅜d
Subtract ⅜d from both sides: -½d - ⅜d = -²¹⁄₁₆ + ⅜d - ⅜d
Simplify: -⅞d = -²¹⁄₁₆
Multiply both sides by 8: 8(-⅞d) = 8(-²¹⁄₁₆)
Simplify: -7d = -²¹⁄₂
Divide both sides by -7: -7d ÷ -7 = -²¹⁄₂ ÷ -7
Simplify: d = ³⁄₂

Can someone please tell me if these triangles are similar or not, and why.
Answers
Answer:
No they are not similar.
Step-by-step explanation:
Because their angles are not the same. 1st triangle: 42-48-90 2nd triangle:58-32-90
Answer:
No, they are not similar.
Step-by-step explanation:
All the angles in a triangle add up to 180°. In both triangles, we already know two of the angles - 42° and 90° in one, 58° and 90° in the other.
Let's see if they match.
180 - 90 - 42 = 48
That's 48, not 58...
Let's check again with the other triangle.
180 - 90 - 58 = 32
48 does not equal 58.
32 does not equal 42.
Therefore, the two triangles are not similar.
The approximate weights of the two animals are 5.12 x 102 lbs. and 6.8 x 102 lbs. Find the total weight of the two animals. Write the final answer in scientific notation with the correct number of significant digits. Can you please help me and stop deleting my question :(
these are the answers
1.2 x 103 lbs.
1.19 x 103 lbs.
11 x 102 lbs.
5.8 x 102 lb
Answers
Answer: Option A is the correct answer
Step-by-step explanation: I took the test and got it right
The total weight of the two animals is 1.19 x 10³ lbs. So the correct option is B.
Given approximate weights of the two animals are as:
1. 5.12 x 10² lbs
2. 6.8 x 10² lbs
We need to find the total weight of the two animals.
Step 1: Add the weights together:
5.12 x 10² lbs + 6.8 x 10² lbs
Step 2: Perform the addition:
(5.12 + 6.8) x 10² lbs
11.92 x 10² lbs
Step 3: Express the result in scientific notation with the correct number of significant digits:
The first number, 11.92, has three significant digits. To maintain three significant digits in the final answer, we can express it as 11.9 (rounding to the nearest tenth) and adjust the exponent accordingly:
11.9 x 10² lbs
This matches option 2 from your provided answers:
2. 1.19 x 10³ lbs.
So, the correct answer is: 1.19 x 10³ lbs.

40°
Step-by-step explanation:
According to the Triangle Sum Theorem: The sum of the measures of the angles in a triangle will add up to 180°.
So with this, you need to add 70° and 70°.
You get 140°
Then to find the last angle, you will subtract the 140° by 180°.
180°-140° = 40°
Hope this helped! :)
Answer:

Step-by-step explanation:
First you add 70 and 70 together to get 140 then minus it by 180.

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.
