Answer:
The first one: the error was that the 3 shouldn’t have been moved but the 5 should have. The correct answer is k=-8
The second one: the error was that they added the 6 and 4, you would only get -10 if the 4 was - the correct answer is -2
You can check your answer by plugging in your answer to the variable and making sure both side equal each other
Step-by-step explanation:
The first one: the 5 should be - from both side so you get k=-8
The second one: the 4 should be + to both sides. And the -6 and +4 should be added together to get n=-2
Remember you always want to get the variables by themselves.
Sorry that was a lot. Hope it helps!
Answer:
1/256
Step-by-step explanation:
=> 1/256
Answer:
yes and no
Step-by-step explanation:
Thus, the ratios 6 : 8 and 12 : 16 are equal. Therefore, they form a proportion. Thus, the ratios 24 : 28 and 36 : 48 are unequal. Therefore, they do not form a proportion.
Answer:
8 and -8
Step-by-step explanation:
0-8= -8
0+8= 8
Both 8 jumps from 0
Answer:
(0,7)
Step-by-step explanation:
For a set of ordered pairs to be a function, there needs to be "ONE" value of y for each unique x value.
Thus, we see that the 3 ordered pairs given have x values of 0, 2, and 3.
Now, we look in the answer choices and find which ones are 0, 2, or 3 in x-coordinate.
That would be only (0,7). Now the original set has x = 0 corresponding to y = 1
Is that true for (0,7)?? NO!
x = 0 will now correspond to "TWO" values of y.
THis will make this NOT A FUNCTION.
So, (0,7) is correct.
