Answer:

Step-by-step explanation:
Given

Transformation: 180 degrees clockwise around the origin
Required
Determine the new coordinates Z'
<em>When a point (x,y) is rotated 180 degrees clockwise around the origin, the new point is: (-x,-y)</em>
<em></em>
So:

Then:

Answer:
(-2,3)
Step-by-step explanation:
Doing it the way you did and working out the problem you substituted 3 into, x+3(3)=7, 3(3) is 9 and then you subtract 9 from both sides.
7-9=-2
x=-2
Then all you have to do is put it into ordered pairs.
(x,y)
(-2,3)
Answer:
Step-by-step explanation:
To write Five times the sum of a number and one you first make "a number" into a variable. In this case let's call it
n
.
Next let's create the sum of a number and one. This would be:
n
+
1
.
Then to get five times this number we need to multiple this expression by five to get:
5
⋅
(
n
+
1
)
Answer: 10 minutes
Step-by-step explanation:
First you have to find out how big the tank is. You will have to you the formula Length x Width x Height. 20 x 18 x 10= 3,600 in. Then you would divide that by 360. 3,600/360= 10. It would have to take 10 minutes to empty the aquarium.
