Answer:
20 Blocks
Step-by-step explanation:
First you would realize that 5 blocks is only 1/4 of the way to school because 1/4 is 25%
Next you should know that you just need to add 5 four times.
Lastly you would multiply 4*5=20
So therefore she lives 20 blocks from her school
Okay, the exponential function is
![g = a^{x}](https://tex.z-dn.net/?f=g%20%3D%20a%5E%7Bx%7D%20)
The start price of it in t=0 is 3,500, as we can see on the graph. Then, the function becomes
![g = 3500^{x}](https://tex.z-dn.net/?f=g%20%3D%203500%5E%7Bx%7D%20)
Let's see at t=2, where the price is g=2000:
![2000 = 3500^{x}](https://tex.z-dn.net/?f=2000%20%3D%20%203500%5E%7Bx%7D%20)
Take natural logarithm:
![ln 2000 = ln 3500^{x}](https://tex.z-dn.net/?f=ln%202000%20%3D%20ln%20%203500%5E%7Bx%7D%20)
![x*ln 3500 = ln 2000](https://tex.z-dn.net/?f=x%2Aln%203500%20%3D%20ln%202000)
![x = \frac{ln 2000}{ln 3500} = 0.93](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7Bln%202000%7D%7Bln%203500%7D%20%3D%200.93)
So, the difference between t=0 and t=2 is
![x_{t=0} - x_{t=2} = 1 - 0.93 = 0.07](https://tex.z-dn.net/?f=x_%7Bt%3D0%7D%20%20-%20%20x_%7Bt%3D2%7D%20%20%3D%201%20-%200.93%20%3D%200.07)
And then we get the change of x in one year equal to 0.035.
So, the final equation is
![g = 3500^{1-0.035t}](https://tex.z-dn.net/?f=g%20%3D%20%203500%5E%7B1-0.035t%7D%20)
You can insert any t and see that it is correct, for example t=7
This question is a little unclear. y= 4x - 3 is already in slope-intercept form. If you use (2,-3), then it would look like -3 = 4(2) - 3...
So when you solve, it’s going to be y=60x-30. So on the graph, you start at -30 and add 60 up and one box over.
