Answer:
1. x = 2, y = -2 prod: -4 / 2 = -2
2. x = 6, y = -6 prod: -36 / 2 = -13
3. x = -1, y = -1 prod: 1 / 2 = 0.5
4. x = -4, y = -1 prod: 4 / 2 = 2
5. x = 10, y = -1 prod: -10 / 2 = -5

Answer:
D. x = 5
Step-by-step explanation:
Add x+3 to both sides and simplify.
9x -3 -8x +(x +3) = 7 -x +(x +3)
2x = 10 . . . . . simplify
x = 5 . . . . . . . divide by 2
__
As you can see, the expression we chose to add (x+3) is the one that results in variable terms being separated from constant terms after simplification.
Say to him if u had 10 28s which one would it be
Okay, so first you draw a picture and let x be the distance from point D to the rest stop. Then the distance from point to the rest stop is 8 - x
You know that the length of the new trail is y + z, where y is the distance from Ancaster to the rest stop and z is the distance from Dundas to the rest stop.
Now by the Pythagorean theorem, y^2 = 4^2 + x^2 and z^2 = 6^2 + (8 - x) ^2
So take square roots of these, add them, and minimize.
Note: I am assuming the path is perfectly straight, otherwise this approach fails.
The reasonable measurement is D.)the distance from New York to California is 2,250 miles
Measurement:
Measurement is the process of comparison of an unknown quantity with a known or standard quantity.
Given,
Mr. Customs is correcting the class’s math homework on customary units. Here we need to find which of the following measurements is reasonable.
By looking at the given options,
A) a pencil is 12 feet long - This one is wrong because the measuring unit of pencil is cm.
B) the back porch is 12 inches wide - For this one we have to use the feet or meter scale.
C) the 3rd hole in the golf course is is 123 miles long - Here this one we have to use either cm or mm.
Therefore, option (D) the distance from New York to California is 2,250 miles is a reasonable statement.
