Answer:
I solved this like you would a system of equations - if that is not the answer you need LMK
Point form:
(- 1/11, 32/11)
Equation Form:
x = -1/11, y = 32/11
Step-by-step explanation:
Answer:
x= -15
Step-by-step explanation:
3x+10=2x-5
3(-15)+10=2(-15)-5
-45+10=-30-5
-35=-35
Each side of the angle is equal, that's how i knew the two were supposed to be equal. <3 Hope this helps!

Answer:
The cost is $43.2
Step-by-step explanation:
The first thing to do here is to calculate the amount of energy consumed.
From the question, we are told that this is;
Power * Time
From the question, power = 1600 watts
Time = 9 hours
So amount of energy consumed = 1600 watts * 9 hours = 14,400 watts hour
It should be known that energy is measured in Kilowatts hour ; So therefore 14,440 watts hour is 14,440/1000 kwh = 14.4 kwh
Now, the cost per unit of energy is $3.00 per kwh
So the cost of using 14,400 watts hour would be 14.4 * 3 = $43.2
