Answer:
d
Step-by-step explanation:
Slope intercept form: y = mx + b
y = -x + 7
x + y = 21
x + y = 21
-x -x
y = -x + 21
y = -x + 7
y = -x + 21
Parallel lines have the same slope. Here, our slope is -1
Therefore, our final answer is d.
Hope this helps!
Answer:
15
Step-by-step explanation:
The formula for factoring a sum of cubes is:
We have a=3f and b=5g here.
So a*b in this case is 3f*5g=15fg.
The ? is 15.
Answer:
ok is this supposed to be a quesion to ask or a fact?
Step-by-step explanation:
Answer: 5
Step-by-step explanation: The median is the middle number in the data set when the data set is written from least to greatest.
Notice that our data set is already written from least to greatest.
1, 2, 2, 8, 9, 14
Notice that in this data set, there is no middle number directly because 2 and 8 fall directly in the middle. In this situation, we take the average of these two middle numbers and divide their sum by 2.
Since 2 and 8 are the numbers that appear in the middle, we add them.
2 + 8 gives us 10.
Now we divide 10 by 2 to get 5.
So the median of this data set is 5.
Use the communicative property of addition to switch to order and you get
13 - 5, so the answer is 8, or k = 8
OR
-5 + 13 = k
Combine like terms
8 = k
or
k = 8<span />
