Answer:
C 3.5.......
Step-by-step explanation:
Your welcome
The answer is y=9x+27 i’m a math teacher
Let x = new apple price
Let y = $0.75 additional price
Let z = original price
3 pounds = apple Sam bought
$5.88 = total amount of apples Sam bought
1st, let
us divide 3 pounds from $5.88
5.88 ÷ 3 = 1.96 this
is the new apple price per pound.
X = $1.96
2nd, if you want to find the original price of
the apples per pound before the increase, we just need to subtract the X to Y.
$1.96 –$ 0.75 = $1.21 is the original price of apple before the increase.
I am assuming that it only 3 pounds of apples, since it will
be a negative / void if it will be 333 pounds, or even 33 pounds.
Answer:
-1
Step-by-step explanation:
First, we need to find which expression to use for f(1). The first function does not include 1, because it is <, and not 
The second functions includes 1, because it has a , meaning greater than or equal to, so this is the function we must use.
-x^2
Plug 1 in for x
-(1^2)
Solve the exponent first
-(1)
-1
So, f(1)=-1
That would be the square root of 2
