You will need to choose one of the equations, and solve for one of the variables. Then, plug the new information into the equation for the variable. Here is an example:   3x - 6y = 12 x + 3y = 3   I choose to work with the second equation, then solve for 'x', which...

(x^3y^2) + (x^2y^2) + (x^2y) You can rewrite the expression to look like this: (x*x*x * y*y) + (x*x * y*y) + (x*x * y) You then ask, "What is the greatest number of x's that I can pull from each term?" Each term has at least one x. If you look closer,...

No. A hot spot is like Hawaii, where there is one location where volcanic activity occurs for some length of time. Then, the plate the volcano is on moves, or shifts. the mountain moves, and a new one is built over the hot spot. This is different from subduction zones, where one plate moves under...

When working with quadratics, the usual formula for working with them is as a trinomial where ax2+bx+c=0. The 'a' 'b' and 'c' are simply coefficients that may or may not be in the formula. If there is no number in front of one or the other of the variables, then the coefficient is assumed...

First thing to know - remember that any number over itself as a fraction equals "1" Now you have to create an improper fraction from the mixed number 4 1/2. Let me know if you have difficulties with this.   What happens if you multiply this new improper fraction by "1"...

a) Slope-intercept form is y=mx+b. You must solve for 'y', and make the 'x' term the first one on the right side of the equation when you are finished.   b) The slope is the 'm' in the equation. it is the number (called the coefficient) that is with the 'x'   c) The...

Ebenezer didn't really show you how to round. He just answered the question for you, which doesn't usually help much. Maybe I can help.   60330.02636   In order to know whether to round the second decimal place up or down, we need to look at the third decimal place. If...
