Answer:

(4, -1) is not a solution to the system

Step-by-step explanation:

The first point: (4,-1) doesn't satisfy the first inequality:

$y>x-5\\(-1) > 4-5\\-1>-1$

since we get to an absurd, because -1 cannot be strictly smaller than -1!

Mr. Champion invests 34,000 into a money-market fund that pays 4.8% simple interest. How long will it take for him to earn $8,16

Tanzania [10]

Answer:

5 years

Step-by-step explanation:

Step one:

Given Information

Principal= $34,000

rate = 4.8%

SImple interest = $8,160

Required

The time T of the investment

Step two:

the expression for simple interest is

$SI= PRT/100$

substitute

$8160 = 34000*4.8*T/100$

cross multiply we have

$8160*100= 34000*4.8*T\\\\816000= 163200T\\\\$

divide both sides by 163200

$816000/163200= T\\\\T= 5 years$

Answer:

$(f-g)(x)$

$f(x)-g(x)$

$x^{2} -6x-27-x+9$

$x^{2} -7x-18$

----------------------

$(f*g)(x)$

$=f(x)g(x)$

$(x^{2} -6x-27)(x-9)$

$=x^{3} -15x^{2}+27x+243$

----------------------

$\frac{f}{g} (x)$

$\frac{x^{2} -6x-27}{x-9}$

$\frac{(x-9)(x+3)}{x-9}$

$x+3$

-----------------------

$(f+g)(x)$

$f(x)+g(x)$

$=x^{2} -6x-27+x-9$

$=x^{2} -5x-36$
