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:
The dollar amount of the meals Sarah served was $1150.
Step-by-step explanation:
Set up an equation expressing Sarah's total earnings:
(total earned) = (base wage) + 0.15 * (price of meals served)
Now the same using what we know:
$252.50 = $80 + 0.15 * x
where x is unknown and can be solved for:
x = (252.50 - 80) / 0.15 = $1150
The dollar amount of the meals Sarah served was $1150.
C, because -22t>66 | : (-22)
t< -3
Answer:
88 squared
Step-by-step explanation:
4 x 2 equals 8.
So 8 x 11 equals 88.
Hopefully I helped :3
THe LCD is x(x^2 - 4)
so multiplying through by this we get:-
2x(x + 2) + 7x = 5(x^2 - 4)
2x^2 + 4x + 7x = 5x^2 - 20
3x^2 - 11x - 20 = 0
(3x + 4)(x - 5 ) = 0
so x = 5 , -4/3
Its the second choice
