Answer:
(Some textbooks describe a proportional relationship by saying that " y varies proportionally with x " or that " y is directly proportional to x .") This means that as x increases, y increases and as x decreases, y decreases-and that the ratio between them always stays the same.

and I know that the second one is the answer I dont know the others
1 * -10 is -10 and 1 + (-10) is -9 so the two factors are 1 and -10
Hope this helps
The first one sqrt29 or 5.38.
The second one is 5.0
By using the distance formula to solve and thinking of the 2 points given as sides of a triangle we solve for the hypotenuse. Taking the difference in the Y values and X values give us the 2 sides and from there we can do a^2 +b ^2 is c^2 to solve for the distance between them
Let the cost of jacket before sales tax be z.
sales tax = $2.38
When the sales tax was included the jacket = $37
Cost of Jacket + Sales tax = 37
z + 2.38 = 37 Equation
z = 37 - 2.38
z = 34.62
Hence cost of jacket = $34.62
Hope this explains it.
