Answer:
Step-by-step explanation:
the length of EG is 6 so G is 6 units away from E. If E is at 3, then G is at 3+6 = 9
X is 12 units away from E so X is at 3 + 12 = 15
This assumes you are not using negative numbers.

Number line are used to represent numbers on a line at regular intervals. The possible coordinates of G is either 10 or -14.
Given that:
[tex]G = 2[/tex]
[tex]EG = 12[/tex]
The equation that calculates EG is:
[tex]EG = |E - G|[/tex]
So, we have:
[tex]12 = |2 - G|[/tex]
Remove absolute brackets
[tex]2 - G = \± 12[/tex]
Add 2 to both sides
[tex]-G =2 \± 12[/tex]
Rewrite as:
[tex]G =-2 \± 12[/tex]
Split
[tex]G =- 2 - 12[/tex] or [tex]G = -2 + 12[/tex]
[tex]G = -14[/tex] or [tex]G = 10[/tex]
The possible coordinates of G are: 10 or -14.

You purchase a $1,500 television. You have to pay 6% sales tax. How much will the tax be on your new television?
Answer:
90 dollars. The total will be $1,590.00.
Step-by-step explanation:
6% of 1500 is 90
We start by converting 6% to a fraction :
6% = 3/50
Then we have
6% of 1500 = 3/50 x 1500 = 3/50 x 1500/1 = 4500/50
Notice that 1500 was rewritten as the fraction 1500/1, and that to multiply two fractions together, you simply multiply the numerators and denominators.
In order to find the simplest form of the fraction 4500/50 we cancel out the greatest common divisor of 4500 and 50, which is 50 :
4500/50=90/1
So the final answer is
6% of 1500=90

Answer:

Step-by-step explanation:
A 90° CCW transformation is ...
(x, y) ⇒ (-y, x)
For A(5, -2), the image point is A'(2, 5).
_____
In your mind, draw a line segment from the origin to point A. You will see that is slope is (rise)/(run) = -2/5.
When you rotate that segment 90° CCW about the origin, it will extend into the first quadrant. The rotated segment is perpendicular to the one you started with, so its slope is ...
-1/(-2/5) = 5/2
That is, it will have a rise of 5 for a run of 2. The point A' will have a x-coordinate of 2 (the run), and a y-coordinate of 5 (the rise).
A'(2, 5)

Find the area the sector. A. 5π/3 mi² B. 9π mi² C. 34π/3 mi² D. 16π mi²
Work Shown:
x = central angle = 255 degrees
r = radius = 4
A = area of sector
A = (x/360)*pi*r^2 ... see note below
A = (255/360)*pi*4^2
A = 34pi/3
note: the formula only works if the central angle x is in degrees. If x is in radians, then use the formula A = (x/2)*r^2

As you are walking down a path, you see a sign telling the path has a 2% grade (ie., a rise of 2 metres for a horizontal change of 100m). Which of the following expressions will calculate the angle between the path and horizontal?
Answer:
Option (A)
Step-by-step explanation:
It has been given in this question that sign telling path has a 2% grade.
2% grade means a rise of 2 meters for a horizontal change of 100 m (As given in the figure attached).
All the trigonometric ratios for the angle θ between the path and the horizontal are,
Sinθ = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
Cosθ = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
tanθ = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
Since measures of the opposite side and adjacent sides are given
Therefore, tangent ratio will be applied to get the measure of the angle,
tanθ = [tex]\frac{2}{100}[/tex]
θ = [tex]\text{tan}^{-1}(\frac{2}{100})[/tex]
Option (A) will be the answer.
The sum of 2 consecutive whole numbers is 206. What are the 2 numbers
Answer:
102.5, 103.5
Step-by-step explanation:
a+a+1=206
2a+1=206
2a=205
a=102.5
103.5
I think there is a bug here. They can't be whole numbers.
Answer:
There are no two consecutive whole numbers that sum to 206 (See proof below)
Step-by-step explanation:
let the first number be x
since the numbers are whole and consecutive, the second number must be (x + 1)
we are given that the number sum to 206
hence,
x + (x+1) = 206
x + x + 1 = 206
2x + 1 = 206 (subtract 1 from both sides)
2x = 206 - 1
2x = 205 (divide both sides by 2)
x = 205/2 = 102.5 (NOT A WHOLE NUMBER)
if x = 102.5, then the second number must be
x + 1 = 102.5 + 1 + 103.5 (ALSO NOT A WHOLE NUMBER)

A linear function is defined by the equation 3x - 2y = 6
what is the x and y intercept
Answer:
X intercept = (2,0)
Y intercept = (0,-3)
Step-by-step explanation:
To find x intercept make y into 0
3(x) - 2(0) =6
3x = 6
x = 2
X intercept = (2,0)
Y intercept do the same
Y intercept make x into 0
3(0) - 2(y) =6
-2y = 6
y = -3
Y intercept = (0,-3)
Answer:
x -intercept is at (2, 0).
y -intercept is at (0, -3).
Step-by-step explanation:
x intercept is found when y = 0:
3x - 2(0) = 6
3x = 6
x = 2.
x intercept is found when x = 0:
3(0) - 2y = 6
-2y = 6
y = -3.

whar is the LCM of 1/6 and 3/8
==========================================
There are 3 methods to find the lowest common multiple (LCM)
---------------------------
Method 1
List out the multiples of 6 and 8
multiples of 6 = {6, 12, 18, 24, 30, 36, 42, 48, ...}
multiples of 8 = {8, 16, 24, 32, 40, 48, ...}
We see that 24 is the smallest number in both sets at the same time. So this is the LCM.
---------------------------
Method 2
Write the prime factorization of 6 and 8
prime factorization of 6 = 2*3
prime factorization of 8 = 2*2*2
The unique prime factors here are 2 and 3. We have 2 show up at most three times meaning that 2*2*2 = 8 is a factor of the LCM. The number 3 is also a factor meaning that 8*3 = 24 is the LCM.
---------------------------
Method 3
Multiply the denominators 6 and 8 to get 6*8 = 48
48 is a common multiple, but its not the smallest
we can divide 48 over the GCF 2 to get 48/2 = 24, which is the actual LCM.
So when you have 2 different denominators, you can multiply their values and then divide by the GCF to get the LCM.
