y = [tex]\frac{1}{2}[/tex] x + 4
Step-by-step explanation:
1). Slopes of ║ lines are equal.
2). Equation of the line passing through the point ( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] ) is
y - [tex]y_{1}[/tex] = m( x - [tex]x_{1}[/tex] )
~~~~~~~~~~~~~~~~~~
y = [tex]\frac{1}{2}[/tex] x - 10 , slope m = [tex]\frac{1}{2}[/tex]
( 2 , 5 )
y - 5 = [tex]\frac{1}{2}[/tex] ( x - 2 )
y = [tex]\frac{1}{2}[/tex] x - 1 + 5

Answer:
x = 85°
y = 45°
Step-by-step explanation:
For x, a line measures 180°, so subtract 95° from 180° to get 85°.
For y, all the angles in a triangle measure to 180°, and since we know x, add it to 50° and subtract it from 180°. 85° + 50° = 135°, and 180° - 135° = 45°
Answer:
x = 85
y = 45
Step-by-step explanation:
for x, angles on a straight line add up to 180 so 95 + x = 180 then evaluate for x
for y, angle in a triangle add up to 180 so 50+85 (as evaluated for x) +y= 180 and evaluate for y
What is the equation of the line that passes
through the point (-2,2) and the point (-6,4)?
Answers
Answer:
y = -1/2x+1
Step-by-step explanation:
First step is to find the slope
m = (y2-y1)/(x2-x1)
= ( 4-2)/(-6 - -2)
(4-2)/(-6+2)
2/-4
-1/2
Then we can use the slope intercept form of a line
y = mx+b where m is the slope and b is the y intercept
y = -1/2x+b
Substitute a point into the equation to find b
2 = -1/2(-2) +b
2 = 1+b
Subtract 1 from each side
1 =b
y = -1/2x+1
y = mx + b
Where m = slope and b is the y intercept
Let's find the slope = change in y/change in x
m = (4-2)/(-6+2) = 2/-4 = -1/2
Now we have:
y = (-1/2)x + b
Now substitute point (-6,4)
4 = (-1/2)(-6) + b
4 = 3 + b
b = 1
So y = (-1/2)x + 1 is the equation

I use the foil method, but if you need to use a different method you can look online at how it is done, but this should give you the correct answer.
First
Outside
Inside
Last
First you multiply 5x and 3x together (the first values in each bracket), which gives you 15x squared (15x^2)
Then you multiply the 5x and 3 (the values on the "outside" of the equation --> first and last) which gives you 15x
Then you multiply the "inside" values (the ones in the middle of all the terms), which is 2 and 3x, and gives you 6x
Last you multiply the 2 values that are last in each bracket, 2 and 3, which gives you 6
So then you put then in order of the exponent
15x^2+15x+6x+6
Then you collect like terms (which means terms that have the same number of the variable) and you're left with the answer
15x^2+21x+6
Then most likely you need to further simplify and you can common factor a number out (take the highest number that evenly mutiplies into each term and divide it out of each), so that you have,
3(5x^2+7x+2)

If the average value of the function f on the interval 2≤x≤6 is 3, what is the value of ∫62(5f(x)+2)dx ?
Answers
The value of the definite integral is 68.
We have,
Break down the integral into two parts:
[tex]\int\limits^6_2 (5f(x) + 2)dx = \int\limits^6_2(5f(x)dx + \int\limits^6_2(2)dx[/tex]
Given that the average value of f(x) on this interval is 3, replace 5f(x) with 5 * 3 = 15:
[tex]\int\limits^6_2 (5f(x)dx = \int\limits^6_2(15)dx[/tex]
= 15(6 - 2)
= 15(4)
= 60
And,
[tex]\int\limits^6_2 2 dx = 2 [6 - 2] = 8[/tex]
Adding both parts of the integral:
= 60 + 8
= 68
Therefore,
The value of the definite integral is 68.

For ellipses:
-First, let's use completing the square method to determine values of a(semi-major axis), b(semi-minor axis), and the coordinates of the center of the ellipse.

-Since the major axis of the ellipse is horizontal, the distance between the center of the ellipse and the co-vertices of the ellipse is ±b.
[tex]\mathsf{CoV_1=(5,3+b)}[/tex][tex]\mathsf{CoV_2=(5,3-b)}[/tex]-The coordinates of the co-vertices of the ellipse are:
[tex]\mathsf{CoV_1=(5,3+2)} \longrightarrow \mathsf{CoV_1=(5,5)}[/tex][tex]\mathsf{CoV_2=(5,3-2)} \longrightarrow \mathsf{CoV_2=(5,1)}[/tex]For the parabola:
-We have the following data:
The parabola is opening to the left and axis symmetry along the major axis of the ellipse (axis of symmetry: y = 3):
[tex]\mathsf{(y-k)^2=-4a(x-h)}[/tex]The focus of the parabola is the center of the ellipses.
F = (5, 3)-The parabola is passing through the co-vertices of the ellipse:
-The parabola is passing through poînts (5, 5) and (5, 1)
-From the first data, we know that the value of k is equal to 3 because the axis of symmetry of the parabola is y = 3.
[tex]\mathsf{(y-3)^2=-4a(x-h)}[/tex]-From the second data, we know that the x-coordinate of the vertex is at h = 5 + a. (Note: the distance of the focus of the parabola and the vertex of the parabola is equal to ±a, since the parabola is opening the the left we use -a)
[tex]\mathsf{F=(5,3)}[/tex]
[tex]\mathsf{F=(h-a,k)}[/tex][tex]\mathsf{5=h-a}[/tex][tex]\mathsf{h=5+a}[/tex][tex]\mathsf{V=(h,k)}[/tex][tex]\mathsf{V=(5+a,3)}[/tex]-Substitute the coordinates of the vertex of the parabola

Using the point (5, 5), x = 5, y = 5:
[tex]\mathsf{(y-3)^2=-4ax+20a+4a^2}[/tex][tex]\mathsf{(5-3)^2=-4a(5)+20a+4a^2}[/tex][tex]\mathsf{4=-20a+20a+4a^2}[/tex][tex]\mathsf{4a^2=4}[/tex][tex]\mathsf{a^2=1}[/tex][tex]\mathsf{a=1}[/tex]-Another way to solve for the value of a is using the formula for the length of the latus rectum (LR = 4a). Since the length of the latus rectum is equal to the minor axis of the ellipse, we can easily solve for the value of a.
[tex]\mathsf{LR=4a}[/tex][tex]\mathsf{4=4a}[/tex][tex]\mathsf{a=1}[/tex]-Substitute the value of a in the equation:

Find the formula for an inverse proportion, knoping that its graph goes through th
point:
(2/3,9/5)
Answers
The graph of this equation runs through the point (2/3, 9/5), and it illustrates an inverse proportion, where y is inversely proportional to x.
What is an inverse proportion?An inverse proportion in mathematics is a relationship between two variables where a rise in one variable causes a fall in the other and vice versa. The two variables are thus inversely proportional to one another.
Let x be the independent variable and y be the dependent variable in an inverse proportion. Then the general form of an inverse proportion is:
y = k/x
where k is a constant of proportionality.
To find the specific formula for an inverse proportion that goes through the point (2/3, 9/5), we can substitute these values into the equation and solve for k:
y = k/x
9/5 = k/(2/3)
Multiplying both sides by (2/3), we get:
k = (9/5) * (2/3) = 6/5
Therefore, the specific formula for the inverse proportion is:
y = (6/5) / x
y = 6/(5x)
This equation represents an inverse proportion, where y is inversely proportional to x, and the graph of this equation passes through the point (2/3, 9/5).
