Answer:
-3
Step-by-step explanation:
-12(x-12)=-9(1+7x)
-12x+144=-9-63x
-12x+63x=-9-144
51x=-153
x=-153/51=-3
<em>Answer: C</em>
<em />
<em />
<em>It is C because when there is a line at the top of the number, it is infinite and repeats many times. That number in a shorter was can be written as a fraction over 990. Two of the answer choices has 990 in it which is letters B and C. This eliminates answer choices A and D. The number that is within the dot is your numerator (645) and 990 is your denominator. Overall the answer is 645/990</em>
Answer:
y = 18.38 + 0.0634x
Step-by-step explanation:
Given,
Monthly base charge = $18.38,
Also, the cost of each kilowatt-hours = 6.34 cents = $ 0.0634
( 1 cents = 0.01 dollars ),
So, the cost of x kilowatt-hours = 0.0634x,
If y represents the total monthly charge ( in dollars ) for x kilowatt-hours,
Thus, the total monthly charge for x kilowatt-hours = base charge + cost of x kilowatt-hours,
⇒ y = 18.38 + 0.0634x
Which is the required equation.
Ax + 32 = 6
- 32 = -32
