But where is the question???
Answer:
18/44
Step-by-step explanation:
To turn 9/22 into something over 44, we need to figure out what to multiply it by.
44 / 22 = 2.
Multiply 9/22 by 2:
9/22 * 2 = 18/44
Answer:
Sorry chief i need to answer 25 questions in 50 minutes
Step-by-step explanation:
Given:
1st recipe
y = 16x + 560
where x is the number of teaspoons of sugar ; y is the total number of calories
2nd recipe
tsps of honey 1 2 4 7
total calories 504 568 696 888
There are 16 calories in a teaspoon of sugar.
There are 64 calories in a teaspoon of honey.
568-504 / 2 - 1 = 64/1
696-568 / 4 - 2 = 128/2 = 64
888-696 / 7 - 4 = 192/3 = 64
The number of positive roots is the number of changes of signs there are, then decrease by 2 each time and stop when you get to 1 or 0
negative roots, sub every x with -x and reevaluate, count change of signs
decrease by 2 each time and stop when you get to 1 or 0
y=+2x⁵-x⁴-2x³+4x²+x-2
+,-,-,+,+,-
1 2 3
3 or 1 positive roots
replace x with -x ( baically flip all signs of odd powerd numbers)
y=-2x⁵-x⁴+2x³+4x²-x-2
-,-,+,+,-,-
1 2
2 or 0 negative roots
3 or 1 positive roots
2 or 0 negative roots
2nd option is answer
