Answer:
A. Positive
Step-by-step explanation:
Since 48 is way larger than 39, we know that if we subtract 39 from 48, we will still get a positive number.
Factor the side effects of equivalent subtract 9 from both sides of the equivalent take the square root of both sides of the equation subtract 10 from both sides of the equation
First add 45 and 55 because sum means addition. 45+55=100 and teiple means multiplication and 3x100= 300 hope this helped :)
X<0
y > 0
so x is negative and y is positive
Quad. II
answer
Quadrant II
Answer:
2x + y = 18
y = 4x - 12
x = 5, y = 8
Step-by-step explanation:
x = 1st number
y = 2nd number
We can use the substitution method as we know what 'y' equals; that value will get plugged in for 'y' in the first equation as follows:
2x + 4x - 12 = 18
6x - 12 = 18
6x = 30
x = 5
y = 4(5) - 12 which is 20-12 or 8
y = 8
