Answer:
x=1/2y+2
Step-by-step explanation:
−4x+2y=−8
Step 1: Add -2y to both sides.
−4x+2y+−2y=−8+−2y
−4x=−2y−8
Step 2: Divide both sides by -4.
−4x
−4
=
−2y−8

Find the Perimeter of Polygon JKLMN. Round to the tenth.
Please help! I am having an insanely hard time with this
9514 1404 393
Answer:
24.1 units
Step-by-step explanation:
This is done using the Pythagorean theorem (or distance formula) to find the lengths of the sides.
For each side of the figure (except the bottom horizontal), you need to identify the dimensions of the right triangle whose hypotenuse is the side of interest. For example, LM is the hypotenuse of a triangle 4 units high and 1 unit wide. The Pythagorean theorem tells you LM has a length of ...
LM = √(4^2 +1^2) = √17 ≈ 4.12
Similarly ...
KL = √(2^2 +2^2) = √8 ≈ 2.83
JK = √(1^2 +6^2) = √37 ≈ 6.08
NJ = √(5^2 +1^2) = √26 ≈ 5.10
Of course, the length of MN is found by finding the difference of the x-coordinates:
MN = 3 -(-3) = 6
Then the perimeter is the sum of side lengths:
4.12 +2.83 +6.08 +5.10 +6.00 = 23.17 ≈ 24.1 . . . units

Three towns are linked by three straight roads. Loretta Adman has created a three-sided billboard that she wants to position as close as possible to all three roads. To do this, she needs to find the ____ of the triangle formed by the three roads.
Answer Choices:
Center
Incenter
Circumcenter
Answer:
c
Step-by-step explanation:
Loretta Adman needs to find the center of the triangle formed by the three roads.
What is Center, Incenter and Circumcenter of the triangle?
Incenter I, whose point is equidistant from the triangle's sides, and circumcenter O, whose point is equidistant from each of the triangle's vertices. A triangle center is a point in the plane that resembles the centers of squares and circles in some ways, meaning that it is roughly in the centers of the figure.
Given: Three towns are linked by three straight roads.
Loretta Adman has created a three-sided billboard that she wants to position as close as possible to all three roads.
The center is in the middle of the figure by some measure.
Therefore, Loretta Adman needs to find the center of the triangle formed by the three roads.

What is the sale price of a stereo that normally sells for $250.00 and is on sale for 10% off?
Answer:
$225.00
Step-by-step explanation
First, take the percentage and switch it to a decimal. 10%= 0.10
Next, take $250.00 and multiply that by 0.10. 250x0.10=25
Lastly, subtract 25 from 250. 250-25= 225.
So you’re final answer is $225.00 Hope this helped!
Answer:
$225
Step-by-step explanation:
To find the sale price you convert 10% to decimals so that is equal to .10. Then you multiply the .10 by the original price, and that equals $25. After you have to subtract the found price by original price (250-25) then that should give you $225.
x^2-12x-6=-65 solve for x
Answer:
x
Step-by-step explanation:
x
Answer:
x = 6 + 4.796i and x = 6 - 4.796i
Step-by-step explanation:
For this problem, we will simply apply the quadratic formula to find the values of x. The quadratic formula is as follows:
x = [-b +/- sqrt(b^2 - 4ac)] / 2a
Using the formula let's find the values of x.
x^2 - 12x - 6 = -65
x^2 - 12x - 6 + 65 = -65 + 65
x^2 - 12x + 59 = 0
The coefficient of x^2 is a, the coefficient of x is b, and the constant 59 is c.
Hence, for our formula we have the following values:
a = 1
b = -12
c = 59
x = [-b +/- sqrt(b^2 - 4ac)] / 2a
x = [-(-12) +/- sqrt( (-12)^2 - 4(1)(59) ) ] / 2(1)
x = [ 12 +/- sqrt ( 144 - 236 ) ] / 2
x = [ 12 +/- sqrt ( -92 ) ] / 2
x = [ 12 +/- sqrt ( -4 * 23 ) ] / 2
x = [ 12 +/- 2i sqrt(23) ] / 2
x = 6 +/- i sqrt(23)
Hence from the formula, we have two possible values for x, both complex solutions. Note, i is an imaginary number.
x = 6 + i sqrt(23) and x = 6 - i sqrt(23)
x = 6 + 4.796i and x = 6 - 4.796i

What is the radius (to the nearest inch) of the child's bicycle wheel? of the child's mountain bicycle wheel? b. The child's mountain bicycle wheel takes 2 seconds to make 3 revolutions . How fast(to the nearest inch per second) is the bicycle moving?
Answer:
36960in per minute
Step-by-step explanation:
Answer:
a) 6 inchesb) 113 inches per secondStep-by-step explanation:
Let the child bicycle wheel radius be x
Then its circumference is
C = 2πxa) Solving for x
37.7 = 2*3.14xx = 37.7/6.28x = 6.0 inb) Mountain bicycle has twice the circumference of a child bicycle
In 2 seconds it makes 3 revolutions
It makes the distance of
d = 3*2*37.7 = 226.2 inches in t = 2 secondsSpeed = d/t
Speed is:
226.2/2 = 113 inches/second

for each dog he walked last summer. This summer, he raised his fee to $9
per dog. Express the change in Logan’s fees as a percent. Round to the nearest tenth of a percent
Answer: 11.11%
Step-by-step explanation: Since he earned 8 dollars for each dog last summer, and he now raised it to 9 dollars per dog, we can make the subtract 9/9 - 8/9, which would equal 1/9. 1 is 11.111% of 9, so that's the answer.
