What is the rate of change of the function?
A rate of change describes how an output quantity changes relative to the change in the input quantity. The units on a rate of change are “output units per input units.” The average rate of change between two input values is the total change of the function values (output values) divided by the change in the input values.

Rewrite the equation below so that it does not have fractions.
Answer:
Step-by-step explanation:
\(2-\frac{3}{4}x =\frac{2}{5}\\8-3x=\frac{8}{5}\\40-15x=8\)
I simply multiplied the equation on both sides by the denominators of each fraction to get whole numbers. You can also do this by multiplying by 20, since the product of the denominators is 20 and will guarantee to create a numerator that creates a fraction that is also a whole number.
20(3/4)=60/4=15
20(2/5)=40/5=8
20(2)=40

scientific notation is hard
Answer:
8.4x10^5 is the first answer. 9.16 x 10^-6 is the second one.
Step-by-step explanation:
Let me explain. To find scientific notation of a number, you have to make the number greater than 1 and less than 10. So for the first number, you would have to move a decimal place 5 times to the right to make 840,000 less than 10 and greater than 1. But, you still have to add the exponent. So the amount of numbers you move the decimal point to the left, that will be your exponent.
2nd. BUT, for the 2nd number, this number is not 1 or greater than 1 or less than 10. So you would have to move it to the right. If your moving a number to the right, remember the exponent will always be negative. So you would move it 6 times to the right.
I hope this made sense. If it didn't, don't worry! You'll get the hang of it.

Is 4 a solution for the equation 5x + 3 = 12? Complete the following statement: The equation is (false, true) when x = 4, so 4 (is, is not) a solution.Is 4 a solution for the equation 5x + 3 = 12? Complete the following statement: The equation is (false, true) when x = 4, so 4 (is, is not) a solution.Is 4 a solution for the equation 5x + 3 = 12? Complete the following statement: The equation is (false, true) when x = 4, so 4 (is, is not) a solution.
Answer:
False, is not
Step-by-step explanation:
If we plug in 4 for x in the equation, we get that 5 * 4 + 3 = 12, and we can calculate that 20 + 3 = 12, which is not true. 4 is a false solution for that equation so it is not a solution (We can use this info to say that the answer is false, is not).
Solve the equation r = 1/(x-1) for x in terms of r. In other words, manipulate the equation until you have x equal to an expression with r's in it but no x's.
Answer:
\(x=\frac{1}{r} +1\)
Step-by-step explanation:
\(r=\frac{1}{x-1}\)
\(r(x-1)=1\)
\(x-1=\frac{1}{r}\)
\(x=\frac{1}{r} +1\)
Answer:
\(x=\dfrac{1+r}{r}\)
Step-by-step explanation:
Given equation:
\(r=\dfrac{1}{(x-1)}\)
Multiply both sides by (x - 1):
\(\implies r(x-1)=\dfrac{1}{(x-1)} \cdot (x-1)\)
\(\implies r(x-1)=1\)
Expand the brackets:
\(\implies rx-r=1\)
Add r to both sides:
\(\implies rx-r+r=1+r\)
\(\implies rx=1+r\)
Divide both sides by r:
\(\implies \dfrac{rx}{r}=\dfrac{1+r}{r}\)
\(\implies x=\dfrac{1+r}{r}\)

Liz's age is two-thirds of Debbie's age. Debbie's age is half of Freya's age. what is the ratio of Liz's age to Freya's age?
Answer:
Let's start by using variables to represent the ages of the three people:
Let L be Liz's age.
Let D be Debbie's age.
Let F be Freya's age.
From the problem, we know that Liz's age is two-thirds of Debbie's age, so we can write:
L = (2/3)D
We also know that Debbie's age is half of Freya's age, so we can write:
D = (1/2)F
To find the ratio of Liz's age to Freya's age, we need to express Liz's age and Freya's age in terms of a common variable. Since we have an equation relating Debbie's age to Freya's age, we can use that as the common variable. From the equation D = (1/2)F, we can solve for F in terms of D:
F = 2D
Now we can substitute this expression for F into the equation for Liz's age:
L = (2/3)D = (2/3)(1/2)F = (1/3)F
So Liz's age is one-third of Freya's age. The ratio of Liz's age to Freya's age is therefore 1:3.

An ant can travel at a constant speed of 980 inches every 5 minutes.
1. How far does the ant travel in 1 minute?
Do not include units (inches) in your answer.
Answer:
196
Step-by-step explanation:
We have been given that an ant can travel at a constant speed of 980 inches in every 5 minutes.
To find the distance traveled by ant in one minute we will divide total distance traveled by time taken to travel that distance.
Therefore, ant travels 196 inches in one minute.

Answer: Range and mean = 8 of both
variance of Set X= 4.7
variance of Set Y= 4.6
Step-by-step explanation:
Two sets of data, set X and set Y are given
a.) Range is the difference of the highest value and the lowest value,
Therefore, Range of set X = 12-4=8
Range of set Y = 12-4=8
Now, Mean of a given data set is the average of all the terms present in the given data set
Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8
Mean of set Y= (4+5+7+32+20+12)/10= 8
Therefore, both the data sets has same range and mean.
b.) Standard deviation tells about the variability of the date and is given by,
S.D= σ = √∑ ( X − μ )^2/n
S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7
S.D of set Y= √(16+9+1+0+4+16)/10= √4.6
Variance is the square of S.D, that is, σ^2
Therefore, variance of set X=4.6
variance of set Y= 4.7
c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?
2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100
The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:
2/8 = j/18
This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:
2/8 = j/18
218 = 8j
36 = 8*j
j = 36/8
j = 4.5
Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.
Answer:
2 over 8 equals j over 18Step-by-step explanation
2 over 8 equals j over 18
This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.
So, the correct proportion is:
2 over 8 equals j over 18
