Answer:
What you found were the x-intercepts of the quadratic function. Here's how you would write it- (2,0), (-9,0).
I think finding the zeroes of a function is equal to finding the x-intercepts, so I believe the two terms can be used interchangeably.
Hope I helped, have a nice day, also please correct me if I did anything wrong
Answer:
-9, 2
Step-by-step explanation:
f(x) = x^2 +7x -18
Set the function equal to zero
0 = x^2 +7x -18
Factor. What two numbers multiply to -18 and add to 7
9*-2 = -18
9+-2 = -7
0 = (x=9) (x-2)
Using the zero product property
x+9=0 x-2 =0
x=-9 x=2
You can also write in coordinate pairs
(-9,0) and (2,0)

P = 2L + 2W ....subtract 2L from both sides
P - 2L = 2W ...divide both sides by 2
(P - 2L) / 2 = W .....can also be written like (P/2) - L = W
Let the balance = Y and the number of weeks = x
She takes out 15 per week, so multiply 15 by x ( the number of weeks) to get 15x.
You would then want to subtract that from the amount she started with in her account.
The equation becomes: Y = 150 - 15x

Step-by-step explanation:
The formula is:
a = h / n.
h = a · n
If a = 0.285 and n = 400, then:
h = 0.285 · 400 = 114
