Answer:
Discount:
$2.85
final price
$54.15
Step-by-step explanation:
Discount = Original Price x Discount %/100
Discount = 57 × 5/100
Discount = 57 x 0.05
You save = $2.85
Final Price = Original Price - Discount
Final Price = 57 - 2.85
Final Price = $54.15
Answer:
The first choice is correct.
Step-by-step explanation:
First work out the common ratio r:-
a2 = a1r and a5 = a1 r^4
So r^3 = a1r^4 / a1r = 256/ 108
r = cube root (256/-108) = 4/3
So the explicit formula is 108(4/3)^(n-1)
Answer:
Step-by-step explanation:
You would first have to plug in for x, (which is already given). After plugging in for x, you would need to solve the equation to get y.
Once you have both x and y, you will have your (x,y)
For example: (given x value = -5)
![f(x) = -|x - 5| -4\\f(-5) = -|(-5) - 5| - 4\\f(-5) = -|-10| - 4\\f(-5) = -10 - 4\\f(-5) = -14\\f(-5) = y = -14\\\\](https://tex.z-dn.net/?f=f%28x%29%20%3D%20-%7Cx%20-%205%7C%20-4%5C%5Cf%28-5%29%20%3D%20-%7C%28-5%29%20-%205%7C%20-%204%5C%5Cf%28-5%29%20%3D%20-%7C-10%7C%20-%204%5C%5Cf%28-5%29%20%3D%20-10%20-%204%5C%5Cf%28-5%29%20%3D%20-14%5C%5Cf%28-5%29%20%3D%20y%20%3D%20-14%5C%5C%5C%5C)
so:
x = -5
y = -14
( -5, -14)
