Two negative signs together change the sign to a positive sign.
Using the distributive property with the 7 you would have -(-7), the two negatives would make it +7
So you end up with -8 + 7
The weights of their backpacks would be discrete
Answer:
Step-by-step explanation:
Set builder notation-
It is a notation for representing a set by enumerating its elements and stating the properties that its members must satisfy.
The given set is,
This set is comprised of all negative integers. So symbol Z should be used in this case.
The set builder notation for this set is,
Let's simplify ~
Therefore, A is the Correct choice !
Answer:
B. y = -3/8x - 4
Step-by-step explanation:
Given equation: 3x - 8y = 12
Find a parallel line that matches one of the equations shown.
First, find the slope by solving for y:
3x - 8y = 12
8y = -3x + 12
y = -3/8x + 12/8
y = -3/8x + 3/2
Slope m = -3/8
Since the slope of a line parallel is the same slope, the only equation that fits the conditions is B because in the form y = mx + b, m = -3/8
