(-1, 8) and (5,-2) equation must be in slope intercept form
The linear equation that passes through (-1, 8) and (5,-2) is:
y = (5/3)*x + 29/3
How to find the linear equation?
A general linear equation in the slope-intercept form is:
y = a*x + b
Where a is the slope, and b is the y-intercept.
If we know that this line passes trhough the points (-1, 8) and (5, -2) then we can write the slope as:
a = (-2 - 8)/(5 + 1) = -10/6 = 5/3
Then we can write:
y = (5/3)*x + b
Now to find the value of b we can replace the values of one of the points in the line, if we use (-1, 8) we will get:
8 = (5/3)*-1 + b
8 + 5/3 = b
24/3+ 5/3 = b
29/3 = b
We conclude that the linear equation is:
y = (5/3)*x + 29/3

Use the table below to answer questions on the number of TV sets per household in the United States. # TV Sets 0 1 2 3 4 5 or more Prob. 0.092 0.275 0.101 0.194 0.035 0.303 a. Verify that this is a probability model. b. Find (3 4) c. Find ( ) d. Find (4) e. Is (4) an unusual event? Why?
From the given discrete probability distribution, we have that:
a) Because the sum of all probabilities is of 1, we can verify that this is a probability model.
b) P(3 or 4) = 0.229.
c) P(at least one) = 0.908.
d) P(4) = 0.035.
e) Since both P(X ≤ 4) and P(X ≥ 4) > 0.05, 4 is not an unusual event.
What is the discrete probability distribution?The probability distribution in this problem gives the probability of a household having a number of TV sets, given as follows:
P(X = 0) = 0.092.P(X = 1) = 0.275.P(X = 2) = 0.101.P(X = 3) = 0.194.P(X = 4) = 0.035.P(X = 5) = 0.303.For item a, we have to add all the probabilities, hence:
0.092 + 0.275 + 0.101 + 0.194 + 0.035 + 0.303 = 1.
Because the sum of all probabilities is of 1, we can verify that this is a probability model.
For item b, we take the probabilities from the table as follows:
P(3 or 4) = P(X = 3) + P(X = 4) = 0.194 + 0.035 = 0.229.
For item c, we follow a similar procedure to item b, taking the probabilities from the table as follows:
P(at least one) = 1 - P(X = 0) = 1 - 0.092 = 0.908.
For item d, from the table, we have that:
P(4) = 0.035.
For item e, we have that:
P(X ≥ 4) = 0.338.P(X ≤ 4) = 0.662.Since both P(X ≤ 4) and P(X ≥ 4) > 0.05, 4 is not an unusual event.

), and D(0, b).
The coordinates of the midpoint of AC¯¯¯¯¯ are (
,b2).
The coordinates of the midpoint of BD¯¯¯¯¯ are (a2,
).
The midpoints of the diagonals have the same coordinates.
Therefore, AC¯¯¯¯¯ and BD¯¯¯¯¯ bisect each other.
Answer:
a, b, a/2, b/2
Step-by-step explanation:
The coordinates of C are (a,b).
You find the midpoint by taking the averages of the coordinates.
The third blank is a/2.The fourth blank is b/2.The length of a rectangle is 7yd more than twice the width x. The area is 555yd2.
(a) Write an equation in terms of x that represents the given relationship.
The equation in terms of x that represents the given relationship is (7 + x)x = 555
Write an equation in terms of x that represents the given relationship.The given parameters are
Length = L
Width = x
Area = 555 yd^2
From the question, we have
L = 7 + x
The area of a rectangle is
A = Lx
Substitute 7 + x for L
So, we have
A = (7 + x)x
Substitute 555 for A
So, we have
(7 + x)x = 555
Hence, the equation in terms of x that represents the given relationship is (7 + x)x = 555

Find the general expression for the slope of a line tangent to the curve of y=x2+2x at the point P(x,y). Then find the slopes for x=−3 and x=0.5. Sketch the curve and the tangent lines.
The general expression for the slope of the tangent line is m = y'(x) = 4x + 2. the value of m is - 10 for x = - 3 and is 4 for x = 0.5.
A line that only touches a curve once is said to be tangent to it. The point (x₀ , y₀) where a line with the equation of a tangent to a curve
y = f ( x ) is given by:
T' (x) = f'(x) (x ₋ x₀) ₊ y₀
The slope of the tangent line to a curve at a point is computed by getting the first derivative of the curve.
y(x)=2x²y
y'(x) = (2)2x²⁻¹ ₊ (1)2x¹⁻¹
y'(x) = 4x¹ ₊ 2x°
y'(x) = 4x ₊ 2(1)
y'(x) = 4x ₊ 2
The slope at a point
P (x, y) is computed by substituting the x-coordinate of the point to the first derivative. This is the general expression for the slope:
m = y'(x) = 4x + 2
For x = - 3
m = 4 (- 3) + 2
m = - 12 + 2
m = - 10
For x = 0.5
m = 4 (0.5) + 2
m = 2 + 2
m = 4
Therefore, the general expression for the slope of the tangent line is m = y'(x) = 4x + 2. the value of m is - 10 for x = - 3 and is 4 for x = 0.5.

Let a = any rational number. Is the absolute difference if a is a positive or a negative number? Explain
Answer: Is the absolute difference if a is a positive number, when a = any rational number.
Step-by-step explanation:
Define Positive numbers:
Positive numbers are the numbers which are greater than zero that lies on the right side of the number line.
Example: 0, 1, 2, 3, 4…
Define Negative numbers:
Negative numbers are the numbers which are less than zero that lies on the left side of the number line.
Example: … -5, -4, -3, -2, -1, 0.
Given data,
Let a = any rational number. Is the absolute difference if a is a positive number.
Because,
Let us take, a = any rational number
We have to know → Is the absolute value of a different if a is a positive number or negative number.
Define Modulus (|x|) of a number :
The modulus or absolute value of a number means the distance that goes from the number to its origin, this is, to the point 0 (zero) that makes part of the real straight line. For instance, the distance from point 6 to its origins is 6, but the distance from point -6 to its origins is also 6.
The modulus operator formula is :
|x| = { x if x ≥ 0 and -x if x ≤ 0
Given question,
Assume any rational number x/y
Using the Modulus property :
|x| = { x/y if x/y ≥ 0 and -x/y if x/y ≤ 0
Therefore, if the rational number is less then zero (say -2).
Then the absolute value will be = - (- 2) = 2
and for any rational number greater than 0 (say 2)
Then its absolute value will be = 2 only.
Hence,
Is the absolute difference if a is a positive number, when a = any rational number.

Find an equation of the circle that satisfies the given conditions. Center (−1, 8); passes through (−3, −5)
Answer:
[tex](x + 1)^2 + (y-8)^2 = 173[/tex]
Step-by-step explanation:
[tex]\textsf{The standard form of the equation of a circle is }\\\\ \sf (x -h)^2 + (y-k)^2 = r^2 \;where\; (h, k) \textsf{ are the coordinates of the center of the circle and \;r\; is the radius}[/tex]
Here h = -1, k = 8
So we get
[tex](x - (-1)) ^2 + (y - 8)^2 = r^2[/tex]
[tex](x + 1)^2 + (y - 8)^2= r^2\\\\[/tex]
Since the circle passes through the point (-3, -5) we can plug in these values of x = -3 and y = -5 to get r squared
[tex](-3 + 1)^2 + (-5 -8)^2 = r^2\\\\(-2)^2 + (-13)^2 = r^2\\\\4 + 169 = r^2\\\\r^2 = 173\\\\\\[/tex]
So the equation of the circle is
[tex](x + 1)^2 + (y-8)^2 = 173[/tex]

The amount that a deposit of $4,500 made today would worth in 6 years is the future value because the initial deposit is the present value.
