Answer:
Step-by-step explanation:
every time x goes up 1, y goes up 4
x = 3 minus x = 2 is a delta (a change of 1)
x = 4 minus x = 3 is a delta (a change of 1)
x = 5 minus x = 4 is a delta (a change of 1)
the delta x is ALWAYS 1 for this table you can always substract x's to find the delta delta is symbolized by Δ Δx for the delta x
y = 7 minus y = 3 is a delta (a change of 4)
y = 11 minus y = 7 is a delta (a change of 4)
y = 15 minus y = 11 is a delta (a change of 4)
the delta y is ALWAYS 4 for this table you can always substract y's to find the delta delta is symbolized by Δ Δy for the delta y
the slope m = Δy / Δx m = 4 / 1 m = 4
y = mx + b when x = 0 then y = b (called the y intercept)
so how do we find the y intercept?
look at the pattern in the TABLE Δx and Δy
when x = 1 y = (3 - 4) = -1
x = 0 y =( -1 - 4) = -5
so y = 4x - 5 is a line equation for the data in this table
I believe there are other forms for linear equations
I chose the y-intercept form
use the point slope equation
(y - y1) = m(x - x1) where (x1, y1) are the coordinates of a point on
the line
when you know the slope of the line and a point on the line
as before
m = (y2 - y1) / (x2 - x1) from the table
= (7 - 3) / (3 - 2) still equals
= 4/1 = 4
pick a point on the line say x= 4 and y = 11 (4, 11)
(y - y1) = m(x - x1)
y - 11 = 4(x - 4) point slope form
solving point slope form for y
y - 11 = 4x - 16 add 11 to both sides
y = 4x - 5 back to the y-intercept form

Which of the following is a valid probability distribution?
The first option is the correct one, that is the valid probability distribution.
Which of the options is a valid probability distribution?For any probability distribution we have two main rules.
The probabilities must be positive.The sum of all the probabilities must be 1.So, with the second rule we can see which one of the tables is a valid distribution, we will see that for table A the sum is:
Sum(A)= 1
And for the other two:
Sum(B) = 1.08
Sum(C) = 0.9
So we can see that the only valid probability distribution is the one in the first option.

On a bike trip, you traveled 21 miles on the first day, 19 miles on the second day, and n miles on the thirdday.
a. Write an expression for the number of miles traveled all three days.
b. Simplify the expression.
PLZ DONT WASTE MY POINTS
Answer:
21 + 19 + x
40 + x
Step-by-step explanation:
well you would just add up 21 + 19 + x. that would be 40 + x. That would be the number of miles
2/3 of 21=? who wants to answer
Answer:
14
Step-by-step explanation:
Convert 21 to a fraction: 21/1
2x21= 42
3x1= 3
42/3= 14
3/3= 1
14/1 --> simplify to 14

what the slope and the y intercept for-12x+4y=-8
Answer:
slope is -3
y-intercept is -2
Step-by-step explanation:
put into slope-intercept form which is y = mx + b where 'm' is slope and 'b' is the y-intercept
12x + 4y = -8
4y = -12x - 8
y = -12/4x - 8/4
y = -3x - 2 (simplified)
The length of rectangle is represented by 8x - 3. The width of the rectangle is represented by 2x. The perimeter is 34 inches. Which equations represent the perimeter? Choose all of the correct answers.
Answer: 20x-6 = 34
Step-by-step explanation:
Given: The length of rectangle is represented by 8x - 3.
The width of the rectangle is represented by 2x.
The perimeter is 34 inches.
Perimeter of rectangle = 2 (length + width)
Perimeter of rectangle = 2 (8x-3+2x)
Perimeter of rectangle = 2 (10x-3)
Perimeter of rectangle = 20x-6
Thus , the required equation that represent the perimeter: 20x-6 = 34

Given equation of a straight line is,
y = -4 - 2x
Domain of the line (x) → {-3, -2, -1, 0, 1}
Therefore, range for the given set of domain will be,
Range (y) → {2, 0, -2, -4, -6}
[By substituting the value of x in the given equation we get the value of y]
Set of scatter points are,
(-3, 2), (-2, 0), (-1, -2), (0, -4), (1, -6)
Now we plot these points to get the discrete graph as attached.

Sum of angles in a quadrilateral = 360°
360° - 128° - 40° - 82° = 110°
Answer:
x = 110
Step-by-step explanation
The sum of the interior angles of a quadrilateral = 360°
Sum the given angles and equate to 360
82 + 40 + 128 + x = 360
250 + x = 360 ( subtract 250 from both sides )
x = 110
