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

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
