Answer:(1,-1)
Step-by-step explanation:
Y= -2x+1
3x -2(-2x*1)=5
3x+(4x-2)=5
7x-2 =5
+2 = +2
7x=7
x= 1
Solution : (1,-1)
9/x^2 - (2x + 1)/8x = 72/8x^2 - x(2x + 1)/8x^2 = (72 - x(2x + 1))/8x^2 = (-2x^2 - x + 72)/8x^2. C is the correct answer.
Answer
Find out the how much fertilizer will Timothy need for two fields, one that is 22.5 acres and one that is 38.25 acres .
To proof
As given
Timothy is putting fertilizer on a field after planting some crops
The directions on the barrel state to use 0.75 quarts for each acre of land.
fertilizer will Timothy need for 22.5 acres = 22.5 × 0.75
= 16.875 quarts
fertilizer will Timothy need for 38.25 acres = 38.25×0.75
= 28.6875 quarts
total fetilizer Timothy need for two fields = 16.875 + 28.6875
= 45.5625
= 45.6 ( approx )quarts
Therefore the total fertilizer will Timothy need for two fields be 45.6 ( approx )quarts .
Hence proved
