How do you simplify -5(m + 9) + 3m + 6(3m – 15)

16m   - 135

Step-by-step explanation:

-5(m + 9) + 3m + 6(3m – 15)

Distribute

-5m + -5*9 +3m +6*3m -6*15

-5m -45 +3m +18m -90

Combine like terms

-5m +3m +18m    -45-90

16m   - 135

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
