Plug in -7 for x in the equation...
f(x) = 3 - 2( - 7 )
f(x) = 3 + 14
f(x) = 17
Answer:
Step-by-step explanation:
you change it to an improper fraction for example 20 2/6x6 3/6
you gotta multiply the 6 in the 20 2/6 by 20 then add the 2 so it would be 122/6 do the same for the other and then you have 39/6 then multiply 122/6x39/6
We know that all black beards cost the same money
And all red beards cost $25
And B represents number of black beards
And R represents number of red beards
We have been given the inequality 20B+25R > 350 to show the target for this month.
The above inequality shows that Merlin needs to make more than 350, hence he made 350 last month
Further, it shows that B has been multiplied by 20, hence the black beard's cost was 20
