OK, so the equation that you've been given is y=1x - 7   This is known as "slope-intercept form" and is the set of letters used to describe is y=mx + b The "m" represents the slope (often described as the "rise over run" - it's how much the line...

31 velocity (answer)

You can use an equation which represents the height of any object that travels up and down (as a projectile) over the course of time, given the initial velocity and the height at which it started. That equation is:   (height at the end of a specific time) = (-16)(time)2 + (initial...

The derivative of a function is basically just the slope of a line drawn tangentially to that function at a point along the curve of the function graph. Since this is a linear function, it has a constant slope (in this case that slope is 3), so the derivative at any of the points along its curve...

84x^5/-7x^5 (answer)

You can simplify it by considering the fraction as having coefficients (#'s) and variables that can each be simplified separately:   84/-7   =  -12   x^5/x^5     =   1     So your answer is the multiplication of those two aspects:     (-12)...

1 mole is a quantity roughly equal to 6.02 x 10^23 (602,000,000,000,000,000,000,000) and it is that quantity no matter what is the object that you are using. 1 mole of electrons would be 6.02 x 10^23 electrons. 1 mole of protons would be 6.02 x 10^23 protons. 1 mole of neutrons would...

The amount of money at the end of the period of time can be modeled using the following function:   A=P(1+r)^t   A is the amount of money at the end P is the amount of money at the start r is the percent interest rate (written as a decimal, so 6% would be 0...
