35=45-n
we do not want negative n so we add n to both sides
n+35=45
now subtract 35 from both sides
n=10
144 - 49 = 95

Answer:
A. The graph of is the graph of stretched vertically, flipped over the x axis, and shifted 7 units down.
Step-by-step explanation:
Given:
In order to transform to , we need to follow the following transformation rules:
1. Multiply the function by the number 2. According to transformation rules, multiplying a function by a positive number greater than 1 results in vertical stretch of the function's graph.
2. Multiply by -1. Multiplying a function by -1 flips it over the x axis.
3. Add -7 to the function obtained in step 2. When a negative number C is added to a function, then the graph shift down by C units. So, here the graph shifts down by 7 units.
Thus, the graph of is the graph of stretched vertically, flipped over the x axis, and shifted 7 units down.
Answer:
(–9,0)
Step-by-step explanation:
f(x) = (x – 8)(x + 9)
= x² + 9x -8x - 72
= x² + x - 72
x-intercept is a coordinate of x axis where a function cuts the x-axis. They are points where y=0 or f(x) = 0.
x² + x - 72 = (x – 8)(x + 9) = 0
∴ x – 8 = 0
x = 8
x + 9 = 0
x = -9
The required points are (8, 0) and (-9, 0).
From the choices given there is only one correct answer. (–9,0)
