Let the number of days needed be x.
First day = 4 miles = 3.5 + 0.5
Second day = 3.5 + 0.5(2)
Third day = 3.5 + 0.5(3)
Equation: 3.5 + 0.5x
<u>Find the number of days needed to run 8 miles:</u>
3.5 + 0.5x = 8
0.5x = 4.5
x = 9
Answer: Casandra 8 miles on the <u>9th day</u>.

Step-by-step explanation:
Answer:
24 ways.
Step-by-step explanation:
In this case, you just need a factorial.
For the first seat, you have 4 students you can place.
For the second seat, you have 3 students.
For the third, you have 2.
For the fourth, you have 1.
So, you can arrange the students by doing 4 * 3 * 2 * 1 = 12 * 2 = 24 ways.
Hope this helps!
Answer:

Step-by-step explanation:
We have the function:

And we want to write its equation after being: 1) Flipped over the x-axis, 2) shifted 4 units down, and 3) shifted 1 unit to the left.
To denote a flip over the x-axis, we multiply the function by -1. Hence:

Is our function flipped over the x-axis.
To shift n units vertically, we simply add n to our function.
Since we are going 4 units <em>downwards</em>, we will add -4 to our function. Hence:

Finally, to shift n units horizontally, we substitute our variable
for
.
Since we are shifting 1 unit to the <em>left</em>, n=-1. Hence, we will substitute
for
. Therefore:

So, our final function is:

Multiply all and get 560
so v= 560
