Answer:
0,1.5
Step-by-step explanation:
y = 510 - 60x
We want to find the domain or the x values where x represents the time
We need to determine the possible values for x
Y cannot be greater than 510 or less than 0. 510 means they have not started the trip, and 0 means they have arrived
510 = 510 -60x
Subtract 510 from each side
510-510 = 60x
0 = 60x
The smallest value of x can be 0
0 = 510 - 60x
Subtract 510 from each side
-510 = 510-510-60x
-510=-60x
Divide by -60
-510/-60 = -60x/-60
8.5 = x
The maximum value of x is 8.5 hours
So x must be between 0 and 8.5 inclusive.
In order to get the answer to this problem you will have to go to the thousands place value and look at the number next to the place value and if the number is greater then 5 then you round up which will give you your answer.
Which means your answer is "692,000."
Hope this helps.
Answer:
-15X^3y^2Z^2 is the answer
Answer:
66. Assuming after you substituted 3 in place of x, you followed order of operations, or PEMDAS.
Step-by-step explanation:
6(2x) + 9x +3 = area
6 (2(3)) + 9(3) + 3 = area
6 x 6 + 27 + 3 = area
36 + 30 = 66
area = 66
