Step-by-step explanation:
Answer:
5900 units per year
Step-by-step explanation:
The average rate of change from (x₁, y₁) to (x₂, y₂) is the slope of the straight line joining the two points.
slope = (y₂ - y₁)/(x₂ - x₁)
From the graph, I estimate your points to be (2006, 35 000) and (2015, 88 000).
slope = (88 000 - 35 000)/(2015 - 2006) = 53 000/9 ≈ 5900 units per year
The average rate of change in the number of digital cameras sold between 2006 and 2015 was 5900 units per year.
Answer:
2
Step-by-step explanation:
-7 x 2 = -14
Let's solve this problem step-by-step.
STEP-BY-STEP SOLUTION:
We will be using simultaneous equations to solve this problem.
Let's establish the two equations we will be using to solve the problem.
Let Andrew's current age = a
Let Andrew's son's current age = s
Equation No. 1 -
a = 3s
Equation No. 2 -
a - 10 = 5s
To begin with, we will substitute the value of ( a ) from the first equation into the second equation to solve for ( s ).
Equation No. 2 -
a - 10 = 5s
( 3s ) - 10 = 5s
3s - 5s = 10
- 2s = 10
s = 10 / - 2
s = - 5
Next we will substitute the value of ( s ) from the second equation into the first equation to solve for ( a ).
Equation No. 1 -
a = 3s
a = 3 ( - 5 )
a = - 15
FINAL ANSWER:
Therefore, the present age of Andrew is - 15 and the present age of Andrew's son's is - 5.
It isn't possible for someone to be negative years old, but this is the answer that I ibtained from the equations.
Hope this helps! :)
