4+3j=43
-4 from both sides
3j=39
then divide both sides by 3 to isolate j
j=12
Answer:
0.547 in.
Step-by-step explanation:
Volume for a rectangular prism is LxWxH.
--> First turn them into decimals:
* 1/2 = 0.5.
* 7/8 = 0.875.
* 1 1/4 = 1.25.
--> Now use the formula:
* 0.5 x 0.875 x 1.25 = 0.547.
Answer:
(-8,1)
Step-by-step explanation:
Imma assume you meant (x-2, y)
x coordinate becomes -6-2=-8
y coordinate stays the same
so the image is (-8,1)

In constructing the equation, you need to know the following:
1. What don't we know? How many minutes you must talk to have the same cost for both calling plans. So, let x be the number of minutes.
2. What do we know? Plan 1 charges $17.50 per month plus $0.17 per minute used and Plan 2 charges $32 per month plus $0.07 per minute used.
So the equation must look like this: 17.50 + .17x = 32 + 0.07x
Solving the equation:
1. Multiply both sides by 100
(100) 17.5 + .17x = 32 + 0.07x (100)
1750 + 17x = 3200 + 7x
2. Subtract 1750 from both sides
1750 + 17x - 1750 = 3200 + 7x - 1750
17x = 7x +1450
3. Subtract 7x from both sudes
17x - 7x = 7x + 1450 - 7x
10x = 1450
4. Divide both sides by 100
10x / 10 = 1450/10
x= 145 minutes
145 minutes is the number of minutes you must talk to have the same cost for both calling plans.
