Answer:
6
Step-by-step explanation:
Since the relationship is proportional, when y is increased by a factor of 3 from 7 to 21, so is x—from 2 to 2×3 = 6.
Answer:
1 .
because sqare root of -1= 1
Just slot the value of x (which is 20), everywhere you see the letter x.
Similarly, slot the value of y (which is 17), everywhere you see the letter y.
So forth,
x + 8 - y
becomes
20 + 8 - 17
which evaluates to 11.
Answer:
3x=18
Step-by-step explanation:
We want to get the variable x by itself.
Since we see a -3 with the 3x, we want to move the 3 to the other side of the equal sign by adding 3 to both sides of the equal sign.
3x - 3 = 15
3x - 3 + 3 = 15 + 3
Then we get:
3x + 0 = 18
3x = 18
So, we have the points. Here are the graphs:
So, the answer is d
