Answer:
a) f(0) = -9
b) f(2) = -5
c) f(-3) = -15
d) f(1/2)=-8
Step-by-step explanation:
We are given the function
and we need to find the following:
a) f(0)
For finding f(0) put x =0 in the given function

So, we get f(0)=-9
b) f(2)
For finding f(2) put x =2 in the given function

So, we get f(2)=-5
c) f(-3)
For finding f(-3) put x =-3 in the given function

So, we get f(-3)=-15
d) f(1/2)
For finding f(1/2) put x =1/2 in the given function

So, we get f(1/2)=-8
Answer:

Let (a) be the first cat
let (b) be the second cat
a +b=11kg-----(1)
a=b+1500g⇒(1.5 kg)-------(2)
so now u have a system of two unknowns
a=11-b
substitute a in (2)
11-b=b+1.5
11-1.5=2b
2b=9.5
b=9.5/2=4.75
subs. b in (1)
a+b=11
a+4.75=11
a=11-4.75=6.25
so cat (a) is 6.25 kg
and (b) is 4.75 kg
hope I helped
Answer:
The students baked 19 pies.
Step-by-step explanation:
Least total pieces of pies sold = 224
Number of pies donated by school cafeteria = 9
Number of pieces of pies donated by school cafeteria = 9×8 = 72
Number of pieces of pies baked = 224 - 72 = 152
Number of pies baked = 152 ÷ 8 = 192
Answer: 40
