Answer:
-9 x 1 x 1 x 1 x 2 = (-18)
-9 + 1 + 1 + 1 + 2 = (-4)
11x10=110
110+40=150
150/6=25
25-8=17
17 is the number.
D. The exclusion is important because we cannot divide by zero. Apart from that we are simply looking at a function.
Step 1: move all terms to one side
7 + 2x^2 - 10x = 0
Step 2: Use the quadratic formula
X = 10 + 2(square root of 11). 10-2 _/—-11

Step 3: Simplify solutions
X= 5 + (square root of 11) 5 - (square root 11)

Please see the attached image for a visual representation of our scale factor. We can set up this proportion by taking the DVD cover and poster values and placing them in fractions. Cross multiply and divide to solve for x.
