How do you find the x and y intercfept?
Set x = 0 and solve the resulting equation in y for the y-intercept. Set y = 0 and solve the resulting equation in x for the x-intercept.
Which property says that if both sides of a true equation are multiplied by the same quantity then the resulting equation is also true?
It is balance
If both entire sides of a true equation are divided by the same non-zero value then the resulting equation is also true?
Yes
If you have four -4s what would you have to do to get the equation resulting in 7?
s=-7/4
How do you find the radius of a cone if you have height and volume?
Use the equation for the volume of a cone, replace the known height and volume, and solve the resulting equation for the radius.
Explain how you an determine if the number is a solution of an equation?
Substitute the number in the equation. If the resulting statement is true the number is a solution to the equation.
When both sides of the equation are squared the resulting equation is?
Remains true. But this does not apply to square roots.
When you square each side of an equation is the resulting equation equivalent to the original?
No. The resulting equation has more solutions. For example, x = 2 has only one solution and that is x = 2.butx2= 4, the squared equation, has two solutions: x = +2 and x = -2No. The resulting equation has more solutions. For example, x = 2 has only one solution and that is x = 2.butx2= 4, the squared equation, has two solutions: x = +2 and x = -2No. The resulting equation has more solutions.

What are the resulting units in the velocity equation for falling raindrops?
m/s
How do you check to see if the value of the variable is a solution to the equation?
Substitute that value in the equation, and then check to see if the resulting statement is TRUE.

How do you determine whether a number is a solution of an equation?
Substitute the value found back into the equation, evaluate the expressions and see if the resulting equation is true.
What is Both entire sides of a true equation are divided by the same non-zero value then the resulting equation is also true?
Yes because this keeps both sides of the equation in balance.
How do you find the radius of a cone if you have height and volume?
Use the equation for the volume of a cone, replace the known height and volume, and solve the resulting equation for the radius.
