Answer:
For scale factors, I believe you just multiply it by how much it says
Step-by-step explanation:
so for 0.5 or 1/2 or let's just say half, you half (-6,4), and get (-3,-2)
(-2,-4) goes to (-1,-2)
(-2,-6) goes to (-1,-3)
(-6,-6) goes to (-3,-3)
Answer:
(7) The value of -j is 9.
(8) The value of -(-j) is -9.
(9) The value of (-j)(-j) is 81.
Step-by-step explanation :
<u>Part 7:</u>
Given algebraic expression is:
j = -9
Now we have to determine the value of (-j).
-j = - (-9) = 9
The value of -j is 9.
<u>Part 8:</u>
Given algebraic expression is:
j = -9
Now we have to determine the value of -(-j).
- (-j) = - [-(-9)] = -9
The value of -(-j) is -9.
<u>Part 9:</u>
Given algebraic expression is:
j = -9
Now we have to determine the value of (-j)(-j).
(-j)(-j) = [- (-9)] × [- (-9)] = 9 × 9 = 81
The value of (-j)(-j) is 81.
2^9=512
There are 512 possible solutions
Answer:
sup dude
Step-by-step explanation:
To solve for the time it takes to travel a certain distance at a certain speed, use the formula,
time = distance / speed
Given that the entire journey takes four hours, add up the time it takes David to row upstream with that of him travelling downstream. This is mathematically represented as,
total time = time upstream + time downstream
4 = 3/(x - 1) + 3/(x +1)
Solving for x in the equation gives 2. Thus, David's speed in still water is 2 miles per hour.
