Answer:
X-42.7
Y-5.34
Step-by-step explanation:
First factor the equation
(x-10)(x+2) = 0
Then solve for (x-10) and (x+2)
x=10
x=-2
Answer:
8.86 x 10^8
Step-by-step explanation:
Scientific notation means that you represent the standard form of a number like this:
number less than ten x 10 to the ___ power
In standard form, the decimal point is at the end of 886,000,000.
You have to move the decimal point to the left until it creates a number less than 10, but greater than 1:
8.86,000,000
You count how many decimal places you moved it. In this case, it is 8.
So your answer becomes 8.86 x 10^8
Alright so, since it says that he eats at least $10 dollars no matter what we can basically leave that alone. next week have $3.50 for every new customer (x) so we could write this as $3.50x. and lastly we have Y the amount he will earn every week.
so the equation would be $10+$3.50x=Y.
if we had more information we might be able to solve for Y but since it doesn't tell us how many he sold we would leave it like that.
Answer:
B 0 ≤x≤9
Step-by-step explanation:
The domain is the input values of the graph. In this graph it is the values that the time variable takes.
Time can take 0 seconds to 9 seconds
0 ≤x≤9
