Answer:
(3/2, -1/2)
Step-by-step explanation:
add the 2 inequalities together.
you get 2X<3 so x<3/2. plug X back in and solve for y and you get y= -1/2
X= total acres on farm
x * 21%= 168
move decimal 2 places to the left to go from percent to decimal form
x * 0.21= 168
divide both sides by 0.21
x= 800 acres
ANSWER: There are a total of 800 acres on the farm
Hope this helps! :)
This simplifies to 25x^8 16y^6.
You square everything in this probelm to get rid of the parentheses.
A.
Start by factoring out an x and then you have a standard trinomial, which you can factor by examining the factors of the final number that add up to the middle number.
