A because for the x values it is always the opposite side and for the y values it is correct. It is also because of the direction of the axes.
Answer:
(x-2 )( x + 1) = (-2 - c)
Step-by-step explanation:
C= - 1 = -x
We cna either multiply x and c until we find HCM before imputing x value and c value that is unknown variable.
To find that we can say x = the average of 1000 + $800 = $900 and work out the difference between the two.
We can use a new variable for half that difference to ensure we add or subtract to find the value 1000 or -1000 again.
So that $1000 - $847 = $153 half this difference is 2/3y so that 4/3 = $153 and 1/3 = 33.333 as we are working with 3 numbers then 1/3 or 2/3 for example could show a debit;
Balance of each 1000 would look like
2/3y + x + c
= c + xy - y1/3
to show smaller amounts for the last 2 debits.
2 Letters chosen among 6 with no repeat:
a) the first has 6 ways
the second has 5 ways
Then to choose 2 letters among 6, with no repeat, there are 6x5 = 30 ways
b) 3 numbers are taken from the digits 0 through 9 with repeats (total = 10)
the first has 10 ways
the second has 10 ways
the third has 10 ways
Then to choose 3 numbers among 10, with repeat, there are 10x10x10= 1000 ways
And the total serial numbers that can be generated is
30 x 1000 = 3000
Answer:
60 grams sugar for 15 biscuits.
3x60 grams of flour, so 180 grams for 15 biscuits.
60÷15= 4 batches.
4 batches with 180 grams each- 4 x 180= 720 grams of flour.
