Substitution Method for Solving Systems of Equations
Homework Statement 5a = 5 - b 5a = 3 - b Homework Equations The Attempt at a Solution I got the solution set to be 1/2, 5/2 i used substitution for substituting a into b of the second equation, just like they were x's and y's just used a's and b's there is no difference...- rcmango

How Do You Find the Slope-Intercept Form with Given Intercepts?
Okay, thanks for the advice, ill definitely keep that in mind. So denominators, and numerators from opposite equations can cancel early for fractions.- rcmango

Solving this equality. Then simple plot.
The way this equality is written is correct. So i reworked the problem, and I get this answer instead. 2* 7/2*x >= -1/4 *2 7x >= -1/2 7x/7 >= -1/2 / 7/1 x>= -1/14 which on a number plot should be about 0 to wherever (infinity)? including 0.- rcmango

Solving this equality. Then simple plot.
Homework Statement 7/2x >= -1/4 then put it on a number plot. Homework Equations The Attempt at a Solution 7x/7 >= -2/4 = -1/2 -1/2 *7/1 = -7/2 x>= -7/2 and I'm not sure if I'm even correct for that answer, and I have to put it on a number plot.- rcmango

Adding variables with same exponents
Homework Statement solve. .2y^3 + .6y^3 - .5y^3 I believe the answer to be .3y^3 Homework Equations The Attempt at a Solution i got the answer to be .8y^3 - .5y^3 = .3y^3 I think this is correct, I'm not sure, please let me know if I finished this correctly.- rcmango
