Answer:
1 and 2 answers are correct
Step-by-step explanation:
2x-y= -8
x-y = -4
ADD BOTH (y is cancelled)
3x= -12
x= -4
-8+y=-8
y=0
-4-y = -4
Multiply all by -1
4+y=4
y=0
Answer:
A. (14,20)
Step-by-step explanation:
The inverse relation is found by swapping x and y in the ordered pair.
When ...
14 = f^-1(20)
then ...
20 = f(14)
The corresponding ordered pair is (14, 20).
Answer:
option 3: 3(10+5) = 30+15
Step-by-step explanation:
They are opposites. since |-3| has the lines around it, this represents absolute value, which is not positive or negative but how far away the value is from 0. the plain -3 remains the same. |-3| is 3, because it is 3 units away from 0 on the number line.
