Answer:
I usually try and practice changing my mindset. Just try to look at things from another perspective, and if you can't, try thinking the OPPOSITE of what you thought.
Think homework is hard? Say to yourself, "Homework is easy." and trudge on through. After some time, your mindset *will* improve, and your attitudes will change from negative to positive.
Also, try to go out more often. Doing exercise, socializing, all of which will produce serotonin and will improve your outlook on life and attitude.

Let the number of large frames sold be X.
Therefore the number of small frames sold is 3X.
So X large frames + 3X small frames = total sales last week.
Now substitute the prices for each item and the total into above equation:
8.99X (large frames) + 3 x 2.99X (small frames) = 233.48 (total sales)
Therefore 8.99X + 8.97X = 233.48
Therefore 17.96X = 233.48
So X = 233.48 / 17.96
Therefore X = 13
So 13 large frames were sold
So if there were 3X small frames sold, there were 3 x 13 sold, which is 39
Therefore 13 large frames and 39 small frames were sold.
(I'm not sure if this is the right method for working out this problem or not, but even if it isn't, hopefully if gives you the idea ;) )
Answer:
√308 or 17.5
Step-by-step explanation:
c^2=a^2+b^2
c^2-a^2=b^2
Substitute
18^2-4^2=b^2
324-16=b^2
b^2=308
b=√308 or b=17.5
For this case, the first thing to do is to observe the cut points with the y axis and the x axis.
We have then that for the following equation:
y = -3x + 15
The cut points are:
Axis x:
0 = -3x + 15
3x = 15
x = 15
Axis y:
y = -3 (0) +15
y = 0 + 15
y = 15
Therefore, the line that best approximates the data is:
y = -3x + 15
Answer:
y = -3x + 15
