Answer:
sorry you out of luck man
Down on the bottom, under the fraction line.
Answer:
Step-by-step explanation:
Let the number = x
8x - 13 = 4x + 3 Add 13
8x = 4x + 3 + 13 Combine
8x = 4x + 16 Subtract 4x
8x - 4x = 16 Combine
4x = 16 Divide by 4
x = 16/4
x = 4
Answer:
No, the absolute value of a number is different from the opposite.
Step-by-step explanation:
For example, the absolute value of 4 is 4.
l4l = 4
But the opposite of 4 is -4.
Absolute value is ALWAYS positive, but the opposite of a positive number is a negative number.
Answer:
Equivalent systems of equations review
Step-by-step explanation:
We're given two systems of equations and asked if they're equivalent.
x + 4y = 8 (1)
4x + y = 2 (2)
Interestingly, if we sum the equations in System A, we get:


Replacing the first equation in System A with this new equation, we get a system that's equivalent to System A:


This is System B, which means that System A is equivalent to System B.
