Given: Y = 7 - x
Substitute this value of y to solve for x in the equation: 2x - y = 8

2x - (7 - x) = 8
2x + x - 7 = 8
3x - 7 = 8
3x = 1
x = 1/3
Substitute this value of x in the … Read more

You can solve this problem knowing a few equations and rules about perpendicular lines.
Y = mx + b (where m is the slope of the line, and b is the y intercept.)
If two lines are perpendicular, their slopes are negative reciprocals.
The slope of the line y = -5/4x + 1 is -5/4, … Read more

You can also solve this using algebra and the following formulas:
Y = mx + b (where m is the slope of the line, and b is the y intercept)
m = (y1 - y2) / (x1 - x2) (equation for finding the slope of a line given two points)
x = a (equation for … Read more

To solve this, first solve for a length (L) that will make the perimeter 90cm exactly.
Perimeter of a rectangle is:
P = 2L + 2W
Where P is the perimeter, L is the length, and W is the width.
Using this we can solve for L by filling in P and W
90 = … Read more

Sounds similar to a form of human colitis except in a dog. Polyps or ulcers in the intestines could be causing the bleeding and the mucus. You should take your dog to a vet, perhaps even call ahead of time and see if they'll need you to bring a stool sample.
There is also good information about … Read more

One thousand thousand's make one million.
For example:
100,000 (One Hundred Thousand)
999,000 (Nine Hundred and Ninety Nine Thousand)
1,000,000 (One Thousand Thousand - One Million)

Two Equations come from the word problem:4950 = 360x + 450yx + y = 12Solve for x in second equation:x + y = 12x = 12 - ySubstitute new x value in first equation and solve for y:4950 = 360(12 -y) + 450y4950 = 4320 - 360y + 450y4950 = 4320 + 90y650 = 90y7 … Read more

According to a University of Florida website, you can kill the chiggers with a hot bath and lots of scrubbing with soap. In fact, it is a good idea to do this when you get back from an outdoor adventure to kill them before they bite you. Stop the itch before it happens!Also, you … Read more
