Which function has an inverse that is a function? a) b(x)=x2+3 b) d(x)=-9 c) m(x)==-7x d) p(x)=x

yes   because as the functions are graphed they eventually will intersect unless otherwise

step-by-step explanation:

if she was to only spend a dollar she can get 1lb

step-by-step explanation:

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
