A certain species of tree grows an average of 0.5 cm per week. Write an equation for the sequence that represents the weekly hei
Anestetic [448]
For this we will use equation:

H = starting height + rate_of_growth*periods
We can mark H with index w to represent how many weeks have passed.
Because all of this we can write:

Hw = 200 + 0.5*w

To calculate height after some number of weeks all you need to do is to exchange w with number of weeks.

Y=5x+2 <br> 4x-y=0<br> is (2,12) a solution of the system?
Svetach [21]

Answer:

The point (2,12) is not a solution of the system

see the explanation

Step-by-step explanation:

we have

y=5x+2 ----> equation A

4x-y=0 ----> equation B

Solve the system by elimination

Adds equation A and equation B

y=5x+2\\4x-y=0\\------\\y+4x-y=5x+2+0\\4x=5x+2\\5x-4x=-2\\x=-2

Find the value of y

substitute the value of x in the equation A

y=5(-2)+2=-8

The solution of the system is the point (-2,-8)

The system has only one solution, because the intersection point both lines is only one point

therefore

The point (2,12) is not a solution of the system
