Answer:
yes (also the c.o.p would be 5)
Step-by-step explanation:
if you model this on a graph, it comes out proportional because its starts from the origin, and its a straight line with no curves.
For this case, the first thing we must do is define variables:
t1: time to drive uphill
t2: time to drive downhill
We now write the system of equations:
t1 = 2 * t2 - 10
t1 - t2 = 65
To rewrite this problem as an equation with a variable, we clear t2 from equation 2:
t2 = t1 - 65
We substitute equation 1 and obtain an equation with a variable:
t1 = 2 * (t1 - 65) - 10
Clearing t1 we have:
t1 = 2t1 - 130 - 10
t1 = 2t1 - 140
2t1 - t1 = 140
t1 = 140 minutes
Answer:
System of equations:
t1 = 2 * t2 - 10
t1 - t2 = 65
Equation with a variable:
t1 = 2 * (t1 - 65) - 10
the drive uphill takes:
t1 = 140 minutes
Answer:
(0, 6), (2, 7)
y = mx + b
m = (7 - 6)/(2 - 0) = 1/2 = 0.5
b = 6
y = 1/2*x + 6
1/2*x - y = -6
So, answer D is correct. But m is the fraction 1/2 and not 12.
Since 450 is less than 500 you would leave it at 10,000
Given:
The total revenue of this year = $14,600
This year revenue is 27% less than their total revenue in the previous year.
To find:
The total revenue in the previous year.
Solution:
Let x be the total revenue of the previous year.
This year revenue is 27% less than their total revenue the previous year.
Revenue in this year = Revenue in previous year - 27% of it
Divide both sides by 0.73.
Therefore, the total revenue in the previous year is $20,000.
