Answer:
mmm, well, not much we can do per se, you'd need to use a calculator.
I'd like to point out you'd need a calculator that has regression features, namely something like a TI83 or TI83+ or higher.
That said, you can find online calculators with "quadratic regression" features, which is what this, all you do is enter the value pairs in it, to get the equation.
Step-by-step explanation:
The two equations would yield no solution if they are dependent. That means that both equations are equivalent. You can determine this by manipulating the equations through simplification. For example, a dependent equation would be:
3x - 4y = 2
3x/2 - 2y = 1
Another dependent equation is when you multiply the whole equation with a number, say 3.
(3x - 4y = 2)3
9x - 12y = 6
Let x=0.6737373...(1)
10x=6.737373...(2)
1000 x=673.737373...(3)
(3)-(2) gives
990x=667
x=667/990
Answer:
9
Step-by-step explanation:
What you do is you plug in the a number into a, b into b, and c into c.
4(4)-(2+5)=9.
Hope this helps.
Answer:
B
Step-by-step explanation:
You can eleminate D right off the bat, no one said they would go if more were planted.
A is just wrong as half of 75 is 35 and 27 is not greater than 35.
It is between B & C but 27/75=.36 which would make B the most correct.
