Hey!
Dean's family has been traveling on the same speed for two days, so to find how far you will need to travel you will need to find how far they are traveling in one hour..
To find this you will need to set up a proportion...
3/195 = 1/x
Solve this proportion by cross multiplying and then dividing..
195 * 1 = 195/3 = 65
This tells you that they are traveling 65 miles per hour. Now with this you will simply have to multiply 65 by 5 to tell you how far they would be traveling in 5 hours with the given speed...
65 * 5 = 325
Your answer of 325 miles tells you how far they traveled.
Hope it Helped!

33% of the salary = (33/100) * 2575
= 849.75
So the income tax = 849.75 dollars
Rise/run or change in y/change in x so 3/2
Answer:
Neither
Step-by-step explanation:
If the sequence was geometric, each term would be multiplied by the same multiplier to get to the next one. We can check if the multiplier is the same by taking a term and dividing it by the term before it. For example,
-4/3.5=-1.14285714
-7.5/-4=1.87500
The multiplier between the terms aren't the same so it's not geometric.
For arithmetic, the distances between each term would be the same, and we can take the same idea from the geometric sequence, but use subtraction instead of division
-4-3,5=-7.5
-7.5-(-4)=-3.5
Again, the distances aren't the same, so it's not arithmetic.
so you're going to need to find the slope. in order to do that use (y2-y1)/(x2-x1)
(7-(-2))/(0-8)
simplify
9/-8
simplify -9/8
now using y=mx+b, we need to find b. so we can plug in the coordinates of (0,7) or (8,-2). let's use (8,-2) because it involves more math.
y=mx+b
-2=(-9/8)(8)+b
multiply (-9/8) by 8 to get -9
-2=-9+b
add 9 to both sides
7=b
so our equation is now
y=-(9/8)x+7
