Answer:
the end behavior is it's going up left and up right
Step-by-step explanation:
since n (the exponent of a(2) is even) it goes up left and up right, another factor that makes it go that way would be the (2) since it is larger than 0
a<0 (but n is even)
goes down left and right
a>0 (n is even)
goes up left and right

Answer:
x=-15/2 and y=7
Step-by-step explanation:
y=-4x-23
y=-2x-8
Two methods, substitution and elimination. Elimination is the easiest, so you can subtract the equations.
y=-4x-23
-(y=-2x-8)
----------------------
y=-4x-23
-y=2x+8
------------ so solve :)
0=-2x-15
becomes 2x=-15
so x=-15/2
------------------------ plug in x to solve for y
and you get y=7
Answer:
The distance between their house on the map is 10 inches.
Step-by-step explanation:
In order to calculate the distance from Jeremy's friend house to his we can apply a rule of three in a way that 60 miles is related to "x" inches in the same proportion as "1 1/2" inches is related to 9 miles. Before applying that it'll be for the best if we convert the mixed fraction to a pure fraction as shown below:
![d = 1\frac{1}{2} = 1 + \frac{1}{2} = \frac{2}{2} + \frac{1}{2} = \frac{3}{2}](https://tex.z-dn.net/?f=d%20%3D%201%5Cfrac%7B1%7D%7B2%7D%20%3D%201%20%2B%20%5Cfrac%7B1%7D%7B2%7D%20%3D%20%5Cfrac%7B2%7D%7B2%7D%20%2B%20%5Cfrac%7B1%7D%7B2%7D%20%3D%20%5Cfrac%7B3%7D%7B2%7D)
Creating the rule of three:
![\frac{60}{9} \frac{\text{miles}}{\text{miles}} = \frac{x}{\frac{3}{2}} \frac{\text{inches}}{\text{inches}}\\\\9*x = \frac{60*3}{2}\\\\x = \frac{180}{18}\\\\x = 10 \text{ inches}](https://tex.z-dn.net/?f=%5Cfrac%7B60%7D%7B9%7D%20%5Cfrac%7B%5Ctext%7Bmiles%7D%7D%7B%5Ctext%7Bmiles%7D%7D%20%3D%20%5Cfrac%7Bx%7D%7B%5Cfrac%7B3%7D%7B2%7D%7D%20%5Cfrac%7B%5Ctext%7Binches%7D%7D%7B%5Ctext%7Binches%7D%7D%5C%5C%5C%5C9%2Ax%20%3D%20%5Cfrac%7B60%2A3%7D%7B2%7D%5C%5C%5C%5Cx%20%3D%20%5Cfrac%7B180%7D%7B18%7D%5C%5C%5C%5Cx%20%3D%2010%20%5Ctext%7B%20inches%7D)
The distance between their house on the map is 10 inches.
