Answer:
-27
Step-by-step explanation:
Solve the system of equations by elimination
Multiply the second equation by 2
-5x + 2y = -51
-2x -2y = -12
Combine
-7x = -63
x = 9
Then, find y by plugging in 9 for x
-(9) - y = -6
-y = 3
y = -3
Then, multiply x by y
(9)(-3) = -27
The answer is 44 the initial value is the amount she started with
Answer:
f(200) =116
f(200) is the cost to rent the moving van and drive it 200 miles
Step-by-step explanation:
f(x) = 90 + 0.13x
Let x = 200
f(200) = 90+ .13(200)
=90+26
=116
f(200) is the cost to rent the moving van and drive it 200 miles
Answer:
Please check the explanation.
Step-by-step explanation:
As the given graph includes distance 'd' at the y-axis and time 't' at the x-axis.
so from the distance-time graph, it is clear that the graph includes 5 chunks.
The first chunk of the graph indicates that the object has started traveling. And the distance 'd' is being covered in time 't', as the slope is upward, hence the speed of the object is increasing.
- Please note that speed is basically the distance covered per unit time.
The second chunk of the graph indicates the no distance is being covered. It means the object is at rest.
The third chunk of the graph indicates that the distance 'd' is being covered in time 't', as the slope is again upward, hence the speed of the object is increasing and the object has started traveling.
The fourth chunk of the graph indicates that the slope is downward, and the object has started traveling to get back to the destination, and eventually, the object has reached the starting point.
So it is 18+7 which is 25 and you make the fraction out of the total books (50).
the fraction is 25/50 which is 0.50 as a decimal
