Answer,
<u><em>-7</em></u>
Explanation,
<u><em>Hello! All we are doing here is simply subtraction :-)</em></u>
<em>-9 - 6 = -15</em>
<em>-15 - (-8) = -7</em>

OK so first I like to find what 10% is which in this case would be 1.8 and to find the other 5% you divide 1.8 by 2 which gets you .9 if you and 1.8 and .9 you get 2.7 and if you add 2.7 to 18 you get 20.7 which is your retail price
Answer: D.
Step-by-step explanation: The smaller the coefficient of a fraction by the quadratic function (the x squared value), the more narrow the graph becomes. 1/4 is larger than 1/9 and the other two whole numbers are still larger than 1/9. Even though -1 is less than 1/9, this only makes the graph flip, not make it any more narrow. Fractions are what squeeze graphs, negatives do not make a difference (i.e. -1/4 is the same size of narrowness as 1/4).
I added 8 on both sides to get 12=3x then I divided by 3 on both sides to get x=4
In the linear format of y=ax+b, b is the y-intercept hence it is 9.
y=ax+9
Then insert (-4,0) which would then be
0=-4a+9
-9=-4a
9/4=a
Thus the answer is y=9/4x+9 which can also be described as 9/4x-y=-9
