Answer: 9
Step-by-step explanation:
1.) you first want to plug in your x= -2
2.) 2*-2^2=1
3.) Solve in order.
4.) 2*-2 = -4
5.) -4 * -2 (your power) = 8 , it is a negative two because x = -2 and where it lands in the order of operations that is how you solve.
6.) 8 + 1 = 9
7.) =9 .

A right triangle is a special triangle that has a right angle. In this case, we have to write a system of inequalities that defines a shaded region that looks like a right triangle. First of all, let's say that at the origin the triangle will have a right angle. To do so, we'd need to set:

So the shaded region in this first part will be the First Quadrant as indicated in the first figure below. So if the opposite side lies on the x-axis the adjacent side will lie on the y-axis or if the adjacent side lies on the x-axis the opposite side will lie on the y-axis. Everything is ok up to this point. We just need to define the hypotenuse, so we'd need to define a line. In order to have a right triangle, we need a line with negative slope and positive y-intercept shaded under the line. So, this inequality could be:

Finally, the system of inequalities would be:

And the final shaded region is the one shown in the second figure.

Alright, lets get started.
At the beginning of her training, she is able to run 2 miles without stopping means 2 will be in the addition when we will write the equation for her running miles.
Her goal is to increase her distance by three quarters of a mile each week.
Means in first week, she will add the distance =
miles
Suppose she runs x weeks, so shee will add distance = 
So, suppose she runs total number of miles = d, then

Where d is total numer of miles she runs
x is number of weeks : Answer
Hope it will help :)
