.60 = republ .40 = democ rep x dem .6 x .4

Math
Divide both sides by 7 and that will isolate y.

Calculus
Take the derivative of the function because the derivative is equal to the slope of the tangent line. a horizontal line has a slope of zero. Set you derivative = 0 and solve for x. That should give you the correct value of x.

math
148 drachma = 1 dollar he spent 10 dollars so he should have 10 = 148 drachma. since the 3 items are priced the same just divide the above answer by 3.

Math
I meant to say s and h. You could do that which issubstitution or you could use the addition/elimination method -6h -6s <= 216 6h +8s >= 245 2s =461

Math
hours: h + s < or equal to 36 6h + 8s > or equal to 245 You can solve these just like you would equations. How would you solve h + s = 36 6h + 8s = 245 Multiply the first equation by -6 and then combine the equations to eliminate the x and solve for y. Substitute back in...

Math
You really need to know how to do it yourself. I can give you a hint. x >= 10 y>= 21 14x + 2y >= 300 (for part C just substitute here) so.. you have to graph x = 10 y = 21 14x + 2y = 300

Math
This is similiar to the one above. Try it based on those hints and I will be happy to check it for you.

Engineering Econonmy
To determine what you would have at the end of 3 or 5 years use: The following formula works for compounded annually. future value = P(1+r)^n for 1500 and 3 years at 8% 1500(1+.08)^3 Do this calculation and a similar one for the 5 year period and then compare.

When a teenager has a baby... what happens? These are things to think about... how does this impact the community? Who pays the hospital bills? Who pays for diapers, formula, etc.? Who pays for the doctor? Can the teenager go back to school? Who watches the baby?
