Answer:
Step-by-step explanation:
look at 2=x-y=2
move this term to the left (2)
it becomes 2=x-y+2=0
and thats your results
Examples: x^2-2x=-1, 3x-x-x+a-a=5, (x^2-1)/(x+1), 2x-(x+x)
Answer:
(x-3)(x^2-7) = x^3 -3x^2 -7x + 21
just change the sign of the root and put x in front of it, then multiply the factors all together
(x-3)(x-sqr7)(x+sqr7) roots come in conjugate pairs to eliminate irrational coefficients
(x-sqr7)(x+sqr7) = x^2-7. similar to (a-b)(a+b) = a^2-b^2
Step-by-step explanation:
.075 will be written as 75/1,000. The fraction can then be simplified to the fraction 3/40.
Powers of ten! is the answer
Answer:
$1.60

6/4.80 1/?
?= 0.8
by writing out the fractions and solving the proportion you will find that one bag costs $0.8. Multiply that by 2 and you get your answer which is $1.60
