Linear equations are one-degree equations. It is a straight-line equation. A linear equation with parameters a and b equal to zero has the conventional form ax + by + c = 0.
What is a linear inequality?The graph of a two-variable inequality is the set of points that describe all solutions to the inequality. The coordinate plane is split in half by a boundary line created by a linear inequality, with one-half representing the solutions to the inequality.
It's a line with a shaded side on one side to show which xy pairings are the inequality's solutions.
Following steps to graph inequalities on a calculator:
1) Press the [Y=].
2) Press [3] [X,T,θ,n] [+] [2] on Y1.
3) Press [◄] six times until the symbol to the left of Y1 is flashing.
4) Press [ENTER] [▼] to select the Line area.
5) Press [►] repeatedly until a triangle pointing to the lower part is displayed.
6) Press [▼] [ENTER].
7) This will change the graph style to shade below the function (this style was chosen because the solution set consists of all real numbers below the line of the y= equation).

Suppose that P, is invested in a savings account where interest is compounded continuously at 6% per year.
When will the investment double itself?
Answer:
We'll need the attached equation.
We'll use as an example that principal = 100 and total =200.
Years = ln (total/principal) / rate
where "ln" means natural log
Years = ln (200/100) / .06
Years = ln (2) / .06
Years = 0.69314718056 / .06
Years = 11.5524530093

Sandra notices a fourth racer called the Whirlwind. Its poster says it covers 1232 yards in 180 seconds. She wants to compare the Whirlwind with the other racers. What is the Whirlwind's speed in yards per seconds to the nearest tenth?
Answer:
6.8yards/seconds
Step-by-step explanation:
Speed = Distance/Time
Given the following
Distance covered = 1232 yards
Time taken = 180 seconds
Substitute to get the speed
Speed = 1232/180
Speed = 6.84
Hence whirlwind's speed in yards per seconds to the nearest tenth is 6.8yards/seconds
Larry and Jack are playing a game of rock-paper-scissors. The probability that Larry will win two times in a row is. Using this probability, determine if the event of Larry winning the first game and the second game was independent, dependent, both, or neither.
The event of Larry winning the first game and the second game was dependent since it was stated that he won two in a row.
How to depict the probability?It should be noted that dependent events are the events that depend on what happened before.
In this event, the first game is being considered in this situation. Therefore, the event of Larry winning the first game and the second game is dependent.

Tangents from same external point have equal length.
KJ = LJ
4x - 1 = 2x + 9
Add 1 to both sides
4x = 2x + 9 + 1
4x = 2x + 10
Subtract '2x' from both side
4x - 2x = 10
2x= 10
Divide both sides by 2
x = 10/2
x = 5

Kelly rides the bus to work d days each month. She pays a fare of $2.25 each time. On t of those days, she pays an additional fare of $0.75 to transfer onto another bus. The expression shown can be used to find her total cost for bus fare for the month.
d × 2.25 + t × 0.75
Which statement explains how to find Kelly’s total bus fare for the month?
Answer: A: find the product of D and $2.25 and the product of t and $0.75. Then find the sum of the two products.
The total fare for the bus can be found by first find the product of d and $2.25 and the product of t and $0.75. Then find the sum of the products.
What are Expressions?Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.
Given that,
The total fare for the bus can be calculated using the expression
d × 2.25 + t × 0.75
Here d is the total days that Kelly worked in a month.
On each of these days, she pays a fare of $2.25.
Total fare now = d × 2.25
Find this product.
There is also an additional fare of $0.75 to transfer onto another bus on t of these days.
Additional fare = t × 0.75
Find this product.
Add the resultant both products.
Hence the statement which explains how to find Kelly's total bus fare for the month is first find the product of d and $2.25 and the product of t and $0.75. Then find the sum of the products.

19 = 12⁰
Step-by-step explanation:
14,15,16 and 17 are formed from perpendicular lines. They are not counted as angles for the kite because, the are in the middle of the kite, not at the side...
You can easily find the angles using the triangle angles formula...to find 12,
