Answer:
<h2><em><u>x = 4</u></em></h2>
Explanation:
10 + 6x + 2x - 7 = 35
- Add Similar Elements: 6x + 2x = 8x
10 + 8x - 7 = 35
8x + 10 - 7 = 35
8x + 3 = 35
- Subtract 3 From Both Sides
8x + 3 - 3 = 35 - 3
8x = 32
8x / 8 = 32 / 8
<h2><u><em>x = 4</em></u></h2>
Answer:
x₁ = 6 and x₂ = 8
Step-by-step explanation:
See the picture below
Answer: After 7 years the number of birds of species A and B are same. and the number of birds during that year will be 140.
Step-by-step explanation:
Given: Sharon is conducting research on two species of birds at a bird sanctuary.
The number of birds of species A is represented by the equation below,where S represents the number of birds, x years after beginning her research.
The number of birds of species B is represented by the equation below,where S represents the number of birds, x years after beginning her research.
To plot the above function, first find points by which they are passing.
For species A, At x=0 ,
At x=2 ,
Similarly find more points and plot curve on graph.
For species A, At x=0 ,
At x=2 ,
Plot a line with the help of these two points.
Now, from the graph the intersection of curve (for A) and line (for B) is at (7,140) which tells that After 7 years the number of birds of species A and B are same. and the number of birds during that year will be 140.
