Answer:

The values for the given function f is defined by $f(x)=\frac{1}{2}x$ is

a) $f(0)=0$ ,

b) $f(18)=9$ and

c) $f(-18)=-9$

Step-by-step explanation:

Given that the function f is defined by $f(x)=\frac{1}{2}x$

Now to find the value of f(0), f(18) and f(-18)

Now take f(0)

Put x=0 in the given function $f(x)=\frac{1}{2}x$ we get

$f(0)=\frac{1}{2}(0)$

$=0$

Therefore $f(0)=0$

Put x=18 in the given function $f(x)=\frac{1}{2}x$ we get

$f(18)=\frac{1}{2}(18)$

$=9$

Therefore $f(18)=9$

Put x=-18 in the given function $f(x)=\frac{1}{2}x$ we get

$f(-18)=\frac{1}{2}(-18)$

$=-9$

Therefore $f(-18)=-9$

The values for the given function f is

a) $f(0)=0$ ,

b) $f(18)=9$ and

c) $f(-18)=-9$

In planning her retirement, Liza deposits some money at 4.5% interest, with twice as much deposited at 5%. Find the amount depos

AlekseyPX

Let

x ----> amount deposited at 4.5%

y ----> amount deposited at 5%

we have that

y=2x----> equation A

4.5%=0.045

5%=0.05

0.045x+0.05y=1,595 ----> equation B

solve the system

substitute equation A in equation B

0.045(x)+0.05(2x)=1,595

solve for x

0.045x+0.10x=1,595

0.145x=1,595

x=11,000

Find y

y=2(11,000)=22,000

<h2>The amount deposited at 4.5% was $11,000 and the amount deposited at 5% was $22,000</h2>
