The sum of two numbers is 18 their difference is 8
2 answers:
When we write out the system of equations, we will get:
x+y=18
x-y=8
We can then use elimination to get just one variable.
x+y=18
+x-y= 8
Which gives us: 2x=26
We then divide by 2 and get: x=13
We next plug that into one of the two equations and solve for the other variable: (13)+y=18
We subtract 13 from both sides and get: y=5
So the two numbers are 13 and 5.

<u>The answer is C</u> . This is because the square of 8 is 64 and the square of 9 is 81. The only number in between those choices is C; 71.
(-4,5) is the correct answer because it needs to be (-y,x) meaning the original x value stays the same because we’re going backwards and the y value changes signs
Volume of oblique cylinder
Answer:
y≤5
Step-by-step explanation:
3 ≥ y - 2
Add 2 to both sides
3 (+2) ≥ y - 2 (+2)
5 ≥ y
or
y ≤ 5
Hope this helps!
