Answer:

Step-by-step explanation:
(5x^3+4x^2)−(6x^2−2x−9)
To find the opposite of 6x^2−2x−9 find the opposite of each term.
5x^3+4x^2−6x^2+2x+9
Combine 4x^2 and 6x^2 to get −2x^2.
5x^3-2x^2+2x+9
Answer:
10% of %450 is $45
SO 1500 divide by $45 is 33.33333
SO it will take a little over 33 weeks

Answer:
X = -8
Step-by-step explanation:
-7(x-5)=91
x-5=-13
x=-13+5
x=-8
Answer:
f = - 
Step-by-step explanation:
Given f varies directly with m then the equation relating them is
f = km ← k is the constant of variation
To find k use the condition f = - 19 when m = 14
- 19 = 14k ( divide both sides by 14 )
-
= k
f = -
m ← equation of variation
When m = 2 , then
f = -
× 2 = -
