Answer: 1/2
Step-by-step explanation: 1 x 3 = 3 and 2 x 3 = 6
ellen had 44 per box and carl had 36 per box
but if they had only two boxes altogether then each box had 80 cans in it
The highest power is 2.
Explanation:
Because x has a maximum power of 2, there will be 2 answers. if it were 3, there could be up to 3 answers, etc.
While solving this problem, you gather all terms on one side so the equation looks like
x
2
−
81
+
17
=
0
x
2
−
64
=
0
then factor
(
x
−
8
)
(
x
+
8
)
=
0
then, because any number times 0 equals 0, we know that one of the two parts in the parenthesis must be equal to 0, so
x
−
8
=
0
or
x
+
8
=
0
and so the two answers
x
=
8
,
−
8
come to be.
Let y be the yield of bushels of wheat in comparison to the amount of rainfall
Let x be the amount of rainfall that occurs (in inches)
If the linear regression equation is y = 47.3 + 0.78x, then per inch of rainfall will yield an addition 0.78 bushels (plugging into x the additional inches of rainfall).
Therefore, on the first inch of rainfall, y = 48.08.
On the second inch of rainfall, y = 48.86.
And so on.
The answer is 12a3 + 2a + 23a + 18
