Based on the bisection of line BC by point A, the value of x is 10/3
<h3>How to determine the value of x?</h3>
The given parameters are:
- Point A bisects BC
- BA = 6x - 3
- AC= 3x + 7
Because the point A bisects BC, then
BA = AC
Substitute the known values in the above equation
So, we have
6x - 3 = 3x + 7
Collect the like terms
6x - 3x = 3 + 7
Evaluate the like terms
3x = 10
Divide both sides of the equation by 3
x = 10/3
Hence, based on the bisection of line BC by point A, the value of x is 10/3

In the year 2009 there were 3500 birds on an island. If the bird population is declining 2.2% per year it means that in the year 2014 we will have 3500*
= 3131.57 birds.
The best prediction is that in the year 2014 the bird population will be 3132.
Answer:
y=1.8
Step-by-step explanation:
first change the fraction into a decimal.
4/5 =0.8
plus the 0.8 to both sides
y=1.8
Answer:
4 bag's
Step-by-step explanation:
Given the bean bag made by beth is in the shape of cube with each side of the cube equal to 2 feet.
Now Also given that each bean bag holds 2 cubic feet of beans.
Let the number of bags of beans recquired are x
The total number of beans available are 2x cubic feet
Now the volume of the bean bag made by beth is
Volume =
Volume = 8 cubic feet
Now 8 = 2x
x = 4
Therefore the number of bag's of beans recquired are 4
Answer:
<h2>y = -4 + 3x</h2><h2>
Step-by-step explanation:</h2>
Let's write the terms:
y = -4 + 3x → (-4) and (3x)
y = -3x + (-4) → (-4) and (-3x)
y = -3x - 4 → (-4) and (-3x)
y = -4 - 3x → (-4) and (-3x)
Other method
1. y = -4 + 3x
2. y = -3x + (-4) = -3x - 4 → 3. <em>use (-)(+) = (-)</em>
3. y = -3x - 4
4. y = -4 - 3x = -4 + (-3x) = (-3x) + (-4) = -3x - 4 → 3. <em>use commutative property</em>
