Write a linear equation in slope-intercept form to represent the data shown in this table.
Bicycle Rental Costs
Time, x(hours) Total cost, y(dollars)
1 $8
2 $16
3 $24
Show your work.
Answer:
[tex]\displaystyle y=8x[/tex]
Step-by-step explanation:
We are given a table and we want to determine a linear equation (in slope-intercept form) that represents this table.
So, we will first need to determine the slope. We can use the slope formula:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Where (x₁, y₁) and (x₂, y₂) are two points.
We have three points: (1, 8), (2, 16), and (3, 24).
Let’s pick two. We can use (1, 8) and (2, 16).
So, let (1, 8) be (x₁, y₁) and let (2, 16) be (x₂, y₂). Substitute appropriately:
[tex]\displaystyle m=\frac{16-8}{2-1}[/tex]
Evaluate:
[tex]\displaystyle m=\frac{8}{1}=8[/tex]
So, our slope is 8.
Now, we can determine the equation using point-slope form:
[tex]\displaystyle y-y_1=m(x-x_1)[/tex]
Where m is our slope and (x₁, y₁) is a point.
We know that the slope is 8, so we will substitute 8 for m.
We can use any of our three points for the point. Let’s use (1, 8) for consistency. So, let (1, 8) be (x₁, y₁). Substitute appropriately:
[tex]\displaystyle y-8=8(x-1)[/tex]
Solve for y. Distribute the right:
[tex]\displaystyle y-8=8x-8[/tex]
Add 8 to both sides:
[tex]\displaystyle y=8x[/tex]
And we have our equation.
Notice that this is a direct variation or proportional equation as we don’t have a y-intercept.

Given f(x)=2^x and g(x)= f(x-3)+4, write the new function rule (equation) for function g and describe (using words) the two transformations that occur between the function f and the function g
*Some good words to consider using would include horizontal, vertical, stretch, compression,
translation, reflection, and phrases such as “to the left”, “to the right”, “up”, “down”, “by a
factor of__, or ”over the __ axis”.
Answer:
Just like Transformations in Geometry, we can move and resize the graphs of functions. Let us start with a function, in this case it is f(x) = x2, but it could be anything: ... g(x) = x2 + C. Note: to move the ... If you change that to (age+4) = 25 then you will get it when you are 21. Adding 4 ... Example: the function v(x) = x3 - x2 + 4x.
Step-by-step explanation:
The graph of the function y = 2x⁴ - 5x³ + x² - 2x + 4 is plotted and attached.
What is a polynomial?Polynomial is an expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variable(s). For example -
y = 4x⁴ + 3x³ + 2x² + 6x + 7
We have the following polynomial functions -
f(x) = 2ˣ
g(x) = f(x - 3) + 4
We can write g(x) as -
g(x) = 2ˣ ⁻ ³ + 4 = (2ˣ/2³) + 4
g(x) = (2ˣ/8) + 4
The graph of f(x) is stretched by the factor of 1/8 and is shifted 4 units upwards.
Therefore, the graph of f(x) is stretched by the factor of 1/8 and is shifted 4 units upwards to given the function g(x)

A 50-centimeter piece of wire is bent into a circle. What is the diameter of the circle? What is the radius of the circle? What is the area of the circle?
Answer:
The diameter will be given by 50 cm ÷ 3.142 = 15.9134 cm
The radius will be 15.9134 ÷2 = 7.9567 cm or about 7.96 cm
The area of a circle is given by \pi × square of radius
Area = 3.142 × 7.96×7.96 = 199.0821 square cm
Answer:
the diameter would be half of the original length because it needs to be a circle so each half of the circle would equal 25 centimeters

Explain the process of solving inequality with variables on both sides. Show an example.
Answer:
Inequalities work exactly like equations with one exception. The process begins just like equations: first, do the opposite of what you see, then do the same thing on the other side of the sign. At the last step of solving an inequality, if you multiply or divide by a negative number, then you reverse the sign
The two examples show the process of solving inequality with variables on both sides are
3 + x > 3x - 6
3 - 4x < 2x + 8
The process is shown below.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal =
Greater than and equal=
We have,
Let us consider an inequality:
3 + x > 3x - 6 ____(1)
3 - 4x < 2x + 8 _____(2)
We will solve for x.
From (1),
3 + x > 3x - 6
Subtract 3 on both sides.
3 + x - 3 > 3x - 6 - 3
x > 3x - 9
Add 9 on both sides.
x + 9 > 3x - 9 + 9
x + 9 > 3x
Subtract x on both sides.
x + 9 - x > 3x - x
9 > 2x
Divide 2 on both sides.
9/2 > x
x < 9/2
This means that x must be less than 9/2.
From (2),
3 - 4x < 2x + 8
Subtract 3 on both sides.
3 - 4x - 3 < 2x + 8 - 3
- 4x < 2x + 5
Subtract -2x on both sides.
-4x - 2x < 2x + 5 - 2x
-6x < 5
Divide both sides by 6.
-x < 5/6
Since we can not keep a negative sign with x we will multiply a negative on both sides and flip the inequality.
- (-x) > -5/6
x > -5/6
Thus,
The two examples show the process of solving inequality with variables on both sides are:
3 + x > 3x - 6
= x < 9/2
3 - 4x < 2x + 8
= x > -5/6

Can yall give me 4 examples of rules of exponents with answers pls?
Answer and Step-by-step explanation:
When multiplying two numbers (or variables) of the same exponent, the solution would have the exponents adding each other:
[tex]a^{x} * a^{y} = a^{x+y}[/tex]
When dividing two numbers (or variables) of the same exponent, the solution would have the exponents subtracting each other:
[tex]a^{x} / a^{y} = a^{x-y}[/tex]
When a number with an exponent is being raised to an exponent, the solution would have the exponents multiplying each other:
[tex](a^{x)^{y} } = a^{xy}[/tex]
When there are two variables in parentheses and an exponent on the outside, the exponent will power both variables:

A bottlenose dolphin is 10 feet below sea level. Then it begins to dive at a rate of 9 feet per second. What is the equation of the line that represents its elevation, y, after x seconds?
A.
y = 9x − 10
B.
y = -9x − 10
C.
y = 9x + 10
D.
y = -9x + 10
Answer:
B. y=-9x-10
Step-by-step explanation:
The dolphin is starting 10 feet below sea level so the y-intercept (or b in slope-intercept form) would be negative 10. Diving means going down, or a negative slope, so the slope would be -9. When you plug those numbers into y=mx+b, you would get y=-9x-10.
