Answer: A rate of change is a rate that describes how one quantity changes in relation to another quantity.
Step-by-step explanation: Hope this help
It tells us the average speed. For instance, if you move 10 meters in 4 seconds, then the average rate of change is 10/4 = 2.5 meters per second. This could apply to moving from one location to another.
It could also be used to describe how much work you can get done over time. For example, let's say you paint 5 square meters of a wall per hour. This is the speed at which you get the job done. After 1 hour, you've painted 5 square meters of wall. After 2 hours, you've painted 2*5 = 10 square meters, and so on.
Another example could be how a population is changing. If there are 100 animals at time 5 hours, then the population becomes 200 animals at time 10 hours, then the rate of change is (200-100)/(10-5) = 100/2 = 50 animals per hour. In other words, the population is going up by 50 animals for every hour.

Answer:
x=−7/5and y=−6/5
Step-by-step explanation:
Step: Substitute−2x−4foryiny=3x+3:
y=3x+3
−2x−4=3x+3
−2x−4+−3x=3x+3+−3x(Add -3x to both sides)
−5x−4=3
−5x−4+4=3+4(Add 4 to both sides)

What fraction is equivalent to 150%?
A. 1 2/5
B. 15/1
C. 3/5
D. 1 1/2
Answer:
D : 1 1/2
Step-by-step explanation:
150% converted into a decimal is 1.5, this is the same as 1 1/2, so the answer is D.
hope this helps :)
The 150% as a fraction in simplest form is D. 1 1/2
What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
We have to write 150% as a fraction in simplest form.
So we put 150 over 100
That is (150/100)
Now multiply the top and the bottom by 10 to get rid of the decimal as;
15/10
1.5 = 1 1/2
Hence, the fraction in simplest form is 1 1/2

The graph of a logarithmic function is shown below.
On a coordinate plane, a curve starts at y = negative 2 in quadrant 4 and curves up into quadrant 1 and approaches y = 2.
What is the domain of the function?
x 0
x < 1
all real numbers
Answer:
x > 0
Step-by-step explanation:
Domain of a function is defined by the set of x-values of the graph of a function.
From the graph attached,
x-values are starting from x > 0 [Since x ≠ 0] and moves towards infinity,
Therefore, domain of the function will be,
(0, ∞) Or x > 0

Answer:
multiply 4 and x and then multiply 4 and 8
Step-by-step explanation:
Answer: x=0.3
Step-by-step explanation:
you would write the equation again
4(x+8)=34-2x time 4 byx and the same on the other side
4x+32=34-2x get rid of the 2x by adding 2x
6x+32=34 get rid of 32 by doing opposite and taking away
6x=2 you want one x so divide by six on both sides

The answer after division is: [tex]2\frac{2}{5}[/tex]
Step-by-step explanation:
The given question involves two mixed fractions that are being divided.
[tex]7\frac{1}{2}\div 3\frac{1}{8}[/tex]
First of all, we will convert the fractions into proper fractions
[tex]\frac{15}{2}\div \frac{25}{8}[/tex]
When the division is performed, the second fraction is reversed
So dividing gives us:
[tex]\frac{15}{2} * \frac{8}{25}\\= \frac{3*4}{5}\\=\frac{12}{5} = 2\frac{2}{5}[/tex]
Hence,
The answer after division is: [tex]2\frac{2}{5}[/tex]

The average rate of change of g(x) over the interval 1 ≤ x ≤ 4 is 27. What is the missing value in the table?
x |0 | 1 | 2 | 3 | 4
g(x)|0 |3| 6 | 15| ?
Answer:
The value of g(x) ar x = 4 is 84.
i.e. g(4) = 84
Step-by-step explanation:
Given the table
x 0 1 2 3 4
g(x) 0 3 6 15 BLANK
The average rate of change of g(x) over the interval 1 ≤ x ≤ 4 is 27.
at x₁ = 1, g(x₁) = 3
at x₂ = 4, g(x₂) = g(4) = ?
The average rate of change = 27
Using the formula involving the average rate of change
Average rate = [g(x₂) - g(x₁)] / [ x₂ - x₁]
substituting x₁ = 1, g(x₁) = 3, x₂ = 4 and Average rate = 27
27 = [g(4) - 3] / [4 - 1]
27 = [g(4) - 3] / [3]
27×3 = g(4) - 3
81 = g(4) - 3
81+3 = g(4)
84 = g(4)
Thus,
The value of g(x) ar x = 4 is 84.
i.e. g(4) = 84

A certain forest covers an area of 3300 km². Suppose that each year this area decreases by 6.75%. What will the area be after 11 years?
Round your answer to the nearest square kilometer.
Answer:
849.75 km^2
Step-by-step explanation:
First, 6.75% is equal to 0.0675
each year, it decreases by 0.0675 x 3300 or 222.75km^2
0.0675 x 3300
222.75 km^2
in 11 years, 11 x 222.75, 2450.25, will be gone
11 x 222.75
2450.25 km^2
that means 849.75 km^2 will be left:
3300 - 2450.25
849.75 km^2
Answer:
849.75
Step-by-step explanation:
3300-222.75x
x is the year
222.75 is 6.75%
3300-222.75(11)=849.75
A car travels 2 5/8
miles in 3 1/2
minutes at a constant speed. Which equation represents the distance, d, that the car travels in m minutes?
Ad = 0.75m
B. d=14 m
C. d = 3.5m
D. d = 2.625m
Answer:
A. d = 0.75m.
Step-by-step explanation:
If, for 3 1/2 minutes (3.5 minutes) the car travels 2 5/8 miles (2.625 miles),
Then in m minutes the car will travel d miles
d = (2.625*m)÷ 3.5
d = 0.75m
