Two negatives equal what?
It is said that two negatives equal a positive when multiplying them with coefficients.
What does Two Kinds refer to?
Two kinds of daughters: obedient and disobedient
What is the key to using the elimination method to find variable terms in the two equations that have equal or opposite coefficients?
Eliminate the variables that have equal coefficients but opposite in sign.x + 2y = 103x - 2y = 14Or you can work to have one of the variables with equal coefficients but opposite in sign such as:3x + 2y = 5x + y = 2 multiply by -2 to both sides3x + 2y = 5-2x - 2y = -4
What is the difference between irrational and transcendental numbers?
An irrational number is a number that cannot be represented as a fraction involving two integers. A transcendental number is a number that cannot be repesented as a polynomial with rational coefficients. Two notable transcendental numbers are pi and e.
What is a ratio that compares two quantities with different kinds of units?
A rate.
What are the two kinds of coefficients?
In terms of mathematics, a coefficient plays the role of a multiplicative factor in a series or an expression. The two different kinds of coefficients include numbers and letters.
What are two examples of two surfaces that have a high coefficient of friction?
Sandpaper and asphalt both have relatively high coefficients of friction.
Riction between two flat surfaces can be divided into two categories What are the two most common kinds of friction?
High friction and low friction.
Friction between two flats surfaces can be divided into two categories what are the two most common kinds of friction?
The friction felt between two flat surfaces can either be sliding friction or static friction.
What are two examples of two surfaces that have a low coefficient of friction?
Ice and glass both have very low coefficients of friction because they are very smooth, so it is easier for a substance to glide over them.
Name two kinds of friction affecting the mouse trap car?
The wheels on the ground create friction
Friction between two flat surfaces can be divided into two categories What are the two most common kinds of friction?
B. static C. kinetic
What two kinds of friction affecting mouse traps?

What are microwelds?
Table of CoefficientsThe coefficient of kinetic friction is always less than or equal to that of static friction.The table below shows many coefficients of friction. Notice that each value is always given for a pair of surfaces. Friction doesn't work unless there are two surfaces.Also note that there are values shown for both static friction and kinetic friction. Static friction deals with starting to move something, while kinetic friction deals with keeping something moving once it's already in motion.In each case, it's also important to note that the coefficients of kinetic friction are always less than or equal to the coefficients of static friction. objectWrite('');Coefficients of Friction for Pairs of SurfacesSurfaces in ContactCoefficient of Static Friction (s)Coefficient of Kinetic Friction (k)Wood on wood0.50.3Waxed ski on snow0.10.05Ice on ice0.10.03Rubber on concrete (dry)1.00.8Rubber on concrete (wet)0.70.5Glass on glass0.940.4Steel on aluminum0.610.47Steel on steel (dry)0.70.6Steel on steel (lubricated)0.120.07Teflon on steel0.040.04Teflon on Teflon0.040.04
Name two kinds of friction affecting mousetrap cars?
Static and Kinetic :)
What are the two kinds of mattter?
There are in-fact 15 kinds of matter that have been proven to exist.
Force that acts between two sticks when they are rubbed together?
Friction. If its done right with the right kinds of woods and preparation, you can make a fire with them by rubbing them in a special way.
