Answer:
8
Step-by-step explanation:
f(1) is another notation for x = 1
so we’ll plug in 1 for x
f(1) = 7((1) -1) +8
f(1) = 7(0) +8
f(1) = 0 +8
f(1) = 8
Answer:
Option C is correct, The scatter plot shows a positive association because y increases as x increases.
Step-by-step explanation:
We are given a graph of scatter plot of points. We need to choose correct option using graph.
Option A: The point (18,2) is an outlier. This point is not shown on graph.
False.
Option B: The scatter plot show linear association. This is not linear association because points are not col-linear.
False
Option C: The scatter plot shows a positive association. This is positive association because y increases as x increases.
True
Option D: The scatter plot shows no association. This is false because it shows positive association.
False
When points are being reflected over the x axis you simply multiply the y value by -1. This makes the last option the correct one.
Well we want to find out how much more will it cost to rent a ski boat than a sailboat for four hours.
All we have to do is Multiply 73 by 4 for the sailboat which gives you $292
Now we do the same for the ski boat. $88 * 4 = $352
So we now have to find out how much more it will cost for a ski boat than a sail boat. All we do is subtract 352 by 292
352
-
292
====
$60
Your answer is $60
Hey there!☺
Let's start by simplifying both sides. First, we distribute.
Now let's subtract 7x from both sides.
Now we will subtract 12 from both sides.
In our last/final step, we will divide both sides by -10.
Now simplify -20/-10.
Hope this helps!
