Elimination because u could multiply the second equation by -3 which would cancel the x and allow you to solve for y and then everntually x but yea elimination is the best method
Step-by-step explanation:
Since



The function has a constant factor so we have a exponential function.
The equation of a exponential function is

Where a is the initial value and b is the growth factor
The growth factor is 3/2,
The initial value in 32

Plug in 4 for x.
You will get 162
Plug in 5 for x you will get
243.
2013- 162
2014- 243
<u>Answer:</u>
y=-1/4x-1
<u>How to find the </u><u>slope</u>
To find the slope of the line you need to do the change in y/change in x. This is also known as the rise/run. To do this you count the spaces in between the two points.
In this graph the change in y (rise) is 2. The change in x (run) is 8. Since the line is going down they are negative. The rise/run is -2/8. This can be simplified to -1/4.
Slope: -1/4x
<u>How to find the y-intercept</u>
To find the y-intercept, you need to look at where the line crosses y.
In this graph the line crosses y at -1.
Y-intercept: -1

Answer:
17
Step-by-step explanation:
4w = w + 51
3w = 51
w = 51 : 3
w = 17
The answer is 20 because if you divide 15:20 by 5, you get 3:4. hope this helps!
