The Answer is A: 255.4 I took the test
Answer:
Number 3 is -17 7/24 yards and Number 2 is -42 1/36 meters
Step-by-step explanation:
Number 3:
-7 2/3 + (-9 5/8)
Then you find common denominator.
-7 16/24 + (-9 15/24)
Add.
-16 31/24
Lastly, Simplify.
-17 7/24
Number 2:
-64 7/9 + 22 27/36
Then you find common denominator.
-64 28/36 + 22 27/36
Add.
-42 1/36
"A parabola is curved instead of linear, in your case it is probably just facing up or down so I won't get into square roots for now.So the quadratic equation that you probably have had to memorize (or will soon) is:
x=(-b[+or-]√(b²-4ac))/2a when you have an equation like ax²+bx+c=0Now where does the curve shape come from? You see that little pesky plus or minus in the equation? That's because there are always 2 values (inputs) that will generate the same output. Example:y=x²(2)²=4(-2)²=...4So if you were to follow this pattern, and plot the points on a graph, you would end up with a curve. You end up with a curve because the slope is constantly increasing.
And this is actually where you start the study of Calculus(!), which is all about measuring slopes (And a bunch of other stuff, but this is the easiest part to explain). Actually, in this case of y=x², the slope at any given point (funnily enough) is equal to 2 times your x-value.
The point is, your line is curved because unlike a linear equation, the slope is changing (at a constant rate)."
