What is an equation of the line that passes through the points (-6,5) and (6,7)
Answers
Answer:
y = 1/6 x + 6
Step-by-step explanation:
m = (y2-y1)/(x2-x1)
m = (7-5)/(6-(-6))
m = 2/12 = 1/6
Substitute x and y values with a pair of coordinates,
y = mx+c
7 = 1/6(6) + c
7 = 1 + c
c = 6
Thus, the equation is y = 1/6 x +6

How do you solve a simple equation?
Answers
Answer:
Solving Simple Equations
When solving a simple equation, think of the equation as a balance, with the equals sign (=) being the fulcrum or center. Thus, if you do something to one side of the equation, you must do the same thing to the other side. Doing the same thing to both sides of the equation (say, adding 3 to each side) keeps the equation balanced.
Solving an equation is the process of getting what you're looking for, or solving for, on one side of the equals sign and everything else on the other side. You're really sorting information. If you're solving for x, you must getx on one side by itself.
Step-by-step explanation:
Addition and subtraction equations
Some equations involve only addition and/or subtraction.
Example 1
Solve for x.
x + 8 = 12
To solve the equation x + 8 = 12, you must get x by itself on one side. Therefore, subtract 8 from both sides equation
X+8=12
- 8 - 8
_____ _____
X = 4
To check your answer, simply plug your answer into the equation:
X+8=12
(4)+8=12
12=12

What is the point slope form
Answers
Answer:
Point-slope is the general form y-y₁=m(x-x₁) for linear equations. It emphasizes the slope of the line and a point on the line (that is not the y-intercept).
Step-by-step explanation:
Answer: y - 2 = -6/5(x - 0)
You use the equation (y - y1) = m(x - x1)
Where y1 and x1 are coordinates of a point on the equation.
If the y intercept is 2, then the point (0, 2) is on the equation.

The answer would be (-0.5, -0.5)
Step-by-step explanation:
This is because when you solve for a mid-point you it's like solving for an average. You would take x1 and x2 and you would find the difference between them. Which would be -0.5. You do the same with y1 and y2. Which would be 3.5.
what is the slope for a line that is parallel to the line y=2/5x-4
Answers
Answer:
2/5
Step-by-step explanation:
The slope of the line

There are 100 bolts in 5 bookcases. What is the unit rate in bolts per bookcase?
Answers
Answer:
20/1
Step-by-step explanation:
The unit rate in bolts per bookcase is 20bolts per bookcase
What is unit rate?There is independent quantity, and a quantity which depends on it (dependent quantity). When independent quantity moves by a unit measurement (single unit increment), the increment in dependent quantity is called rate of increment of dependent quantity per unit increment in independent quantity.
We are Given that 100 bolts in 5 bookcase
We need to find the unit rate in bolts per bookcase
Number of bolts in 5 bookcases= 100
Number of bolts in 1 bookcases= 100/5
= 20
So, it will be 20 bolts everyday

Write a quadratic function in standard form with zeros -4 and -3
Answers
Answer:
y = x² + 7x + 12
Step-by-step explanation:
Given the zeros x = - 4 and x = - 3, then the corresponding factors are
(x - (- 4) ) and (x - (- 3) ), that is
(x + 4) and (x + 3)
The function is then the product of its factors
y = (x + 4)(x + 3) ← expand using FOIL
= x² + 7x + 12
The center of an ellipse is (-9,3). One focus is (-6,3). The
major axis is 14 units long.
What is the equation of the ellipse in standard form?
Enter your answer by filling in the boxes.
Answers
Answer:
49 in first box, 40 in second box. I took the test.
The equation of an ellipse with center (-9, 3), focus (-6, 3) and major axis length of 14 units is [tex]\frac{(x+9)^2}{49} + \frac{(y-3)^2}{40}= 1[/tex]
The standard form of the equation of an ellipse is:
[tex]\frac{(x-h)^2}{a^2} + \frac{(y-k)^2}{b^2}= 1[/tex]
The center of the ellipse, (h, h) = (-9, 3)
That is, h = -9, k = 3
The length of the major axis = 14 units
The length of the major axis = 2a
2a = 14
a = 14/2
a = 7
a² = 7²
a² = 49
The coordinates of the foci are [tex](h \pm c, k)[/tex]
One of the foci = (-6, 3)
h - c = -6
-9 - c = -6
c = -9 + 6
c = -3
[tex]c^2 = a^2 - b^2\\(-3)^2 = 7^2 - b^2\\9 = 49 - b^2\\b^2 = 49 - 9\\b^2 = 40[/tex]
Substitute a² = 49, b² = 40, h = -9, and k = 3 into the equation [tex]\frac{(x-h)^2}{a^2} + \frac{(y-k)^2}{b^2}= 1[/tex]
[tex]\frac{(x+9)^2}{49} + \frac{(y-3)^2}{40}= 1[/tex]
The equation of an ellipse with center (-9, 3), focus (-6, 3) and major axis length of 14 units is [tex]\frac{(x+9)^2}{49} + \frac{(y-3)^2}{40}= 1[/tex]

Determine if this series converges or diverges. Find the sum if possible. 250, 50, 10...
Answers
Answer:
50
Step-by-step explanation:
Answer:
312.5
Step-by-step explanation:
We have the series: 250, 50, 10...
As we can see, each subsequent term gets smaller and smaller. Eventually, it will be infinitesimally small. So, our series converges.
We can also see this from our common ratio. Each term is 1/5 of the previous term. Since our r 1/5 is less than 1, our series will converge.
Since it converges, we can indeed find our sum. First, we can write our series using summation. This will be:
[tex]\displaystyle{\sum_{n=0}^{\infty} 250(\frac{1}{5})^n }[/tex]
We can use the following infinite geometric series formula:
[tex]\displaystyle{\sum_{n=0}^{\infty} ar^n=\frac{a}{1-r}[/tex]
So, let's substitute 250 for a and 1/5 for r. This yields:
[tex]\displaystyle{\sum_{n=0}^{\infty} 250(\frac{1}{5})^n }=\frac{250}{1-\frac{1}{5}}[/tex]
Subtract:
[tex]\displaystyle{\sum_{n=0}^{\infty} 250(\frac{1}{5})^n }=\frac{250}{\frac{4}{5}}[/tex]
Divide. So, our series converges to:
[tex]\displaystyle{\sum_{n=0}^{\infty} 250(\frac{1}{5})^n }=312.5[/tex]
And we're done!
