I think it is 64 cause i multiplied
domain is {2.4, 4.8, 6.3, 8.8, 10.1 }
For domain, equate f(x) to each value in the range and solve for x
7x - 2.7 = 14.1 ⇒ x = 
= 2.4
7x - 2.7 = 30.9 ⇒ x = 
= 4.8
7x - 2.7 = 41.4 ⇒ x = 
= 6.3
7x - 2.7 = 58.9 ⇒ x = 
= 8.8
7x - 2.7 = 68 ⇒ x = 
= 10.1
Step-by-step explanation:
David makes 17(25)
and
Linda maked 25(7)
so it would make the equation 17(25)+25(7)
425+175 together they would be making
600 dollars a week
If it is 40% off, then u are paying 60%
0.60(20) = 12 <== on sale, it is 12 pounds
R(x) is a polynomial. Thus, the domain is the same as the range.
Domain = range = ALL REAL NUMBERS.
We can also express the answer as
(-infinity, infinity).
