Answer:
A linear equation is a fancy term for a straight line, which can be created by joining 2 points.
A point can be defined by (x, y), where x and y are the horizontal distance and the vertical distance respectively from point (0,0) (called the origin).
There are 3 ways to define a line:
(1) The slope-intercept form
y = mx + b, in which m is the slope, b is the y-intercept, where the line crosses the vertical axis at (0, b). If values of m and b are given, you can substitute and write the equation right away.
The slope, m, is calculated by rise (vertical difference between 2 points on the line) divided by run (horizontal difference between the 2 points on the line)
Step-by-step explanation:
or example, if 2 points on the line are
(x1, y1) and (x2, y2)
Then slope = (y1– y2)/(x1 — x2)
If m > 0, then the line rises to the right.
If m = 0, then the line is horizontal.
If m < 0, then the line rises to the left.
If the line is in the form x = c, where c is a constant, then the line is vertical.
(2) Point slope form
m = (y — y1)/(x — x1), when (x1, y1) and m are given.
In other words,
m(x — x1) = y — y1
mx — m(x1) = y — y1
y = mx — m(x1) + (y1)
Note that b = -m(x1) + (y1)
(3) linear form
ax + by + c = 0, where a, b, and c are constants.

While watching a football game, Jordan decided to list yardage gained as positive integers and yardage lost as negative integers. After these plays, Jordan recorded 14, -7, and -9. What was the overall gain or loss?
Answer:
There is a loss of 2 yards.
Step-by-step explanation:
To find the overall gain or loss, we add or subtract there values.
Initially, we have 0 yards.
Records 14, so 0 + 14 = 14, that is, for now a gain of 14
Then loses 7, so 14 - 7 = 7, for now a gain of 7.
Then, 7 - 9 = - 2, so in all, there is a loss of 2 yards.
A sweater was on sale for 40% off regular price LSA saved $20 by buying that sweater on sale what was the regular price of the sweater
Answer:
The original price of the sweater was $28
Step-by-step explanation:
To find out the answer to this problem you need to first convert the percent into a decimal which would be 0.4 and then to solve the problem in one step you need it to be 140% which would be 1.4 as a decimal. Then you need to multiply 20 by 1.4 which gives you 28 and 28 would be the total cost of the shirt at it's regular price.
Answer:
$50
Step-by-step explanation:
Sale on sweater = 40% .
Money saved = $20 .
Let original price be x then ,
=> 40% of x = $20
=> 40x/100 = $20
=> x = $20 *100/40
=> x = $ 50

The scale factor of the triangle ΔABC to the triangle ΔA'B'C' will be 2/3. Then Annyie says correctly.
What is a transformation of a shape?A point, line, or mathematical figure can be converted in one of four ways, and each has an effect on the object's structure and/or position.
Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered. There is no effect of dilation on the angle.
From the graph, the length of AC is given as,
AC = 9 - 3
AC = 6 units
From the graph, the length of A'C' is given as,
A'C' = 6 - 2
A'C' = 4 units
The scale factor is given as,
Scale factor = A'C' / AC
Scale factor = 4 / 6
Scale factor = 2/3
The scale factor of the triangle ΔABC to the triangle ΔA'B'C' will be 2/3. Then Annyie says correctly.

Steven has 20 tickets to use at the carnival. Jared has 4 tickets to use at the carnival. How many times as much is the amount of tickets Steven has than Jared?
i accidentally answered this one instead of another one sorry
Steven has five times more tickets than Jared.
What is Multiplication?'Multiplication is an operation that represents the basic idea of repeated addition of the same number.'
According to the given problem,
If we add the number of tickets till it equals Steven's number of tickets,
= 4 + 4 + 4 + 4 + 4
= 20
This can also be represented as 4 × 5 = 20
Hence, we can conclude that Steven has five times more tickets than Jared.

Let N be the number of data entries in a population and n be the number of data entries in a sample data set. Describe the difference between the calculation of population standard deviation and sample standard deviation.
Answer:
Step-by-step explanation:
During the calculation of any population standard deviation, the sum of the squared deviation is usually divided by N, which is the number of data entry in the population. Thereafter, the square root of the result would be taken.
On the other hand, during the calculation of the sample standard deviation, the sum of the squared deviations is usually divided by n - 1, with n being number of entries in the sample data set. Thereafter, the square root of the result would be taken.

is 2880 a perfect square? if not, find the smallest multiple of 2880 which is a perfect square. find the square root of the new number
Step-by-step explanation:
2880 = 2⁶ * 3² * 5.
Since not all the prime factors of 2880 have even powers, 2880 is not a perfect square.
Instead, 2⁶ * 3² * 5² is a perfect square as all its prime factors have even powers. The square root of this new number is 2³ * 3 * 5 = 120.
