since 48/12 = 4
4(44 +3) = 4 x 47 = 188
E is the midpoint of BC. If BE = 50 and CE = 2x + 25, find the value of x.
Answer:
The value of [tex]x[/tex] is [tex]\frac{25}{2}[/tex].
Step-by-step explanation:
From Analytical Geometry we get that ratio of BC to BE is:
[tex]\frac{BC}{BE} = 2[/tex] (From definition of midpoint)
[tex]\frac{BE+CE}{BE} = 2[/tex]
[tex]1 + \frac{CE}{BE} = 2[/tex]
[tex]\frac{CE}{BE} = 1[/tex]
[tex]CE = BE[/tex]
If we know that [tex]BE = 50[/tex] and [tex]CE = 2\cdot x + 25[/tex], then, the equality above is expanded:
[tex]2\cdot x +25 = 50[/tex]
[tex]2\cdot x = 25[/tex]
[tex]x = \frac{25}{2}[/tex]
The value of [tex]x[/tex] is [tex]\frac{25}{2}[/tex].
A person has a rectangular garden that has a length of 11 feet longer than the width. Set up a quadratic equation
to find the dimensions of the garden if its area is 126 ft2. Solve the quadratic equation to find the length and
width.
Answer: width = 7, length = 18
Step-by-step explanation:
Area (A) = Length (L) x width (w)
Given: A = 126, L = w + 11
126 = (w + 11)w
126 = w² + 11w
0 = w² + 11w - 126
0 = (w - 7)(w + 18)
0 = w - 7 0 = w + 18
7 = w -18 = w
↓
Disregard because width cannot be negative
L = w + 11
= 7 + 11
= 18

Among all pairs of numbers (x,y) such that 3x+y=15, find the pair for which the sum of squares, x^2+y^2, is minimum. Write your answers as fractions reduced to lowest terms.
Answer:
(4.5, 1.5)Step-by-step explanation:
Lets substitute y in the second equation and find its minimum
3x + y = 15y = 15 - 3xSubstitute
x^2 + y^2x^2 + (15 - 3x)^2 =x^2 + 225 - 90 x + 9x^2=10x^2 - 90x + 225This expression gets minimum value at x = -b/2a as quadratic function's vertex:
x = -(-90)/2*10 = 90/20 = 4.5Then finding the value of y:
y = 15 -3*4.5 = 15 - 13,5 = 1.5The answer is (4.5, 1.5)
Answer:
[tex](9/2, 3/2)[/tex]
Step-by-step explanation:
We have the equation:
[tex]3x+y=15[/tex]
Which is equivalent to 15 among all pairs of (x, y).
We want to find the pair of solutions (x, y) such that:
[tex]x^2+y^2[/tex]
Is minimum.
Note that our given equation is a line.
And the equation x²+y² is a circle centered on the origin.
In other words, we want to find the radius of the circle such that it is tangent to our line at 3x+y=15.
It must be tangent because this guarantees that it is the smallest value of x²+y².
It's good if we have a visual of this. I've graphed the given linear equation. Please refer to it.
If you remember in geometry, in order for the radius to be tangent to a line, the radius must be perpendicular to our line.
So, let's find the perpendicular equation to our line. Our original equation is:
[tex]3x+y=15[/tex]
Subtract 3x from both sides:
[tex]y=-3x+15[/tex]
So, the slope of our original equation is -3.
This means that the slope of our perpendicular line must be the negative reciprocal of -3. Namely, it is 1/3.
And since our circle is centered on the origin, this line will go through the origin. Therefore, our perpendicular equation is:
[tex]y=\frac{1}{3}x[/tex]
Graphing this will yield (please refer to the second graph):
Therefore, the intersection between our old and new line is at (4.5, 1.5).
Therefore, the (x, y) value that grants the minimum sum is 9/2 and 3/2.
We can check this by substituting them into our second equation. This yields:
[tex](9/2)^2+(5/2)^2[/tex]
Square and add:
[tex]=81/4+9/4=22.5[/tex]
Note that 22.5 is the radius squared.
Graphing this gives us (please refer to the third graph):
We can see that it is indeed tangent to our line. And it is the lowest value of P that does so.
So, our answer is x=9/2 and y=3/2.

A point lies on AB and is the distance from A to B. Point A is located at (4, 8) and point B is located at (14, 10)
What are the coordinates of this point?
o (11), 9)
o (6,8)
O (6, 6)
o (9, 9)
Help please
Answer:
(9,9)
Step-by-step explanation:
Assuming the point is exactly halfway between A and B, to find it we just need to find the centre point between (4,8) and (14,10).
To find the midpoint, we just need to find the middle value, by dividing the difference between the x values by 2, and repeating the process with the y values.
This is because the point is in the middle, so it's y value will be in the middle of the given AB y values, and its x value will also be directly in the middle of the AB x values.
The x values are 4 and 14. The midpoint is
14-4=10
10/2=5 (the midpoint is 5 away from each reference point)
4+5=9
The midpoint is 9 for the x values. This means the x-value for the point is 9.
Repeat for y-values:
10-8=2
2/2=1
8+1=9
The midpoint is 9, therefore it has the y coordinate of 9.
Therefore the coordinates for the point are (9,9).

Step 1: Write equation
(x - 8)² = -8
Step 2: Solve for x
Square root both sides: x - 8 = √-8Factor out negative: x - 8 = √-1 · ±√8Simplify: x - 8 = ±i2√2Add 8 to both sides: x = 8 ± 2i√2Answer:
x = 8 ± 2i√2

what other ratio is related to 3 : 9
3: 9 is related to 1:3
Step-by-step explanation :
Reducing ratios is the same as reducing fractions. When doing this, we find the GCF of the numerator and denominator. Then we divide the numerator and denominator by the GCF.
The GCF is 3.
3:9 = (3/3) : (9/3) = 1:3
Answer:
1 : 3 is related to 3 : 9
Step-by-step explanation:
According to ratios you can always divide them if they are even numbers like for example the ratio, 6 : 9 is uneven but you can divide each number by 3 and you get a ratio of 2 : 3. and they are both alike because if you go back and multiply each number by three you get the same ratio that you had before.
