3(4-y) = 5(y+2), what does y =
An expression does not have answers or solutions because it's not an equation.
[ 8x - 2 = 14 ] is the equation.[ x = 2 ] is the solution to the equation.
2X^2 - 11X - 21 = 0 quadratic equation X = -b +/- sqrt(b^2 -4ac)/2a a = 2 b = - 11 c = - 21 X = -(-11) +/- sqrt[(-11)^2 - 4(2)(-21)]/2(2) X = [11 +/- sqrt( 289)]/4 X = [11 +/- 17]/4 X = 7 X = - 3/2 My TI-84 graphs original equation and confirms answers
you have to do a fair test to know that your answers are reliable.

The equation for the Pythagoras Theorem is written as: a2 + b2 = c2. The theory of this equation is to provide analysis of the sum of squares from 2 different sides.
Analysis of Variance (ANOVA) compares 3 or more means. The t-test would only compare 2 means.
We don't provide test answers. Sorry.
the maximum number of solutions to an euation is equal to the highest power expressed in the equation. 2x^2=whatever will have 2 answers

What is the answer for number 2
Wiki Answers can not be trusted for example: Answer: 2+2=5
There are 2 answers, +sqrt 7 and -sqrt7. Generally, the highest exponent in the expression (in this case 2) is the maximum number of possible answers.
