Answer:
A
Step-by-step explanation:
You can eliminate B and D because it’s using
, but the question is asking
. So it’s either A or C. They are both written correctly, but out of the two, A is correct because just that x ≠
part of it is what makes it true.
The reason being is that the only thing that won’t make
true is when the denominator equals 0, because anything divided by 0 is undefined. So, when you plug
for x in the denominator you get:
. The
part just turns into 7, and 7 - 7 is 0. So you don’t want x to equal
.
<u>So the answer is A:</u>
,
±
There you go my friend!
I hope you understand and that this helps with your question! :)
Answer:
$29500
Step-by-step explanation:
Given data
The number of months is 60
the downpayment is $5,500
the monthly payment is $400
Let the function for the total payment be given as
y=mx+c
y= 400(60)+5500
y=24000+5500
y= 29500
Hence the total paid for the car is $29500

Answer:
500 phones
Step-by-step explanation:
cost of manufacturing: y = 80x + 10,000
money from phone sales: y = 100x
* note: x = #phones
solve for when they're equal;
100x = 80x + 10,000
100x - 80x = 80x - 80x + 10,000
20x = 10,000 –––––––––––> divide both sides by 20
x = 500
