Answer:
Let x be the numbers of cones sold and y be
profit for the selling of cones.
When number of cones (x) increases then profit must be increased.That means, y is directly proportional to x
only one equation y = 2x satisfy this condition. all other equations does not satisfy the condition.
y = 2x gives that if the x number of ice cream sold the the profit made is 2x.
y = 8 + x (all time profit is number of item plus 8)
y = x – 8 (all time profit is number of item minus 8)
y = 2x – 8 (all time profit is 2 times number of item plus 8)
y = 2x Each item get Rs.2 profit. It is valid

Answer:
60
Step-by-step explanation:
The corresponding angles of the triangles are given, y + 10 and 2y - 40. You need to first find the value of the variable (in this case, y), and to do this, you need to set them equal to one another:
y + 10 = 2y - 40
<u>Subtract y from both sides:</u>
<u />
y + 10 = 2y - 40
-y -y
____________
10 = y - 40
<u>Add 40 to both sides:</u>
<u />
10 = y - 40
+40 +40
________
50 = y
Now that we have the value of y, you need to plug the value into one of the expressions (either one will come out with the same answer):
y + 10
50 + 10 = 60
<em><u>OR</u></em>
<u />
2y - 40
2(50) - 40
100 - 40 = 60
<u />
The absolute value of -6.4 is 6.4,
so -|-6.4| = -6.4
A. -|-6.4| = - 6.4 incorrect
B. |-6.4| = 6.4 6.4 is greater than -6.4 the answer is B.
