Answer:
15x^5*y^3
Step-by-step explanation:
Answer:
I believe the one that is selected is correct.
Step-by-step explanation:
1/5k - 2/3j and -2/3j + 1/5k
If you switch the subtraction to addition, 2/3 becomes negative, while 1/5 stays the same.
Answer:
B. x ≈ 13/8
Step-by-step explanation:
We assume that one iteration consists of determining the midpoint of the interval known to contain the root.
The graph shows the functions intersect between x=1 and x=2, hence our first guess is x = 3/2.
Evaluation of the difference between the left side expression and the right side expression for x = 3/2 shows that difference to be negative, so we can narrow the interval to (3/2, 2). Our 2nd guess is the midpoint of this interval, so is x = 7/4.
Evaluation of the difference between the left side expression and the right side expression for x = 3/4 shows that difference to be positive, so we can narrow the interval to (3/2, 7/4). Our 3rd guess is the midpoint of this interval, so is x = 13/8.
_____
The sign of the difference at this value of x is still negative, so the next guess would be 27/16. It is a little hard to tell what the question means by "3 iterations." Evaluating the function for x=13/8 will be the third evaluation, so the determination that x=27/16 will be the next guess might be considered to be the result of the 3rd iteration.
Answer:
$36.6 for 20 pints of ice cream
Step-by-step explanation:
4 pints = $7.32.
20 pints = ?
you need to cross multiply or you can just multiply $7.32. with 5.
Answer:

Step-by-step explanation:
x - 2 (x -
) = 2 (4 - x) + 10
x − 2 ×
=2(4−x)+10
x−(−x)=2(4−x)+10
x+x=2(4−x)+10
2x=2(4−x)+10
2x=8−2x+10
2x=−2x+18
2x+2x=18
4x=18
