Answer:
y=-2 x=-2
Step-by-step explanation:
y=-x-4
y=x
you can plug y in for x in the first equation by using substitution
y=-y-4
and then you solve for y
2y=-4
y=-2
so y equals -2. Since y=x, x also equals -2. Therefore
y=-2 x=-2

Step-by-step explanation:
The trick is always to look at the number after the first decimal for rounding to 1 decimal place, if its above 5, you round it up to the next decimal; eg. 13.45 = 13.5 because the 5 will round it up,and if value below 5, you round it down; eg. 12.34 = 12.3 because the 4 is below 5 and the nearest 10th decimal is 3.
Step-by-step explanation:
Step 1: Multiply the numerators from each fraction by each other (the numbers on top). The result is the numerator of the answer.
Step 2: Multiply the denominators of each fraction by each other (the numbers on the bottom). ...
Step 3: Simplify or reduce the answer.
it's really simple if you still need help tell me
