This does not look easy to factor, so I'd suggest using the quadratic formula:
-1 plus or minus sqrt( 1-4(3)(-5) )
x = -----------------------------------------------
2*3
-1 plus or minus sqrt(61)
= ------------------------------------
6
Thus, there are 2 real, unequal, irrational roots / solutions.
Answer: 25
Step-by-step explanation: 8*5=40, so multiply 5 by 5. Or, to put it another way:
5/8 = 25/40
You would owe the rental shop 54 dollars
13.00 x 5.00 = 18.00
since it is per hour you multiply 18.00 x 3
3 stands for the hours you kayaked
and that gives you 54
therefore your answer is 54<span />
Answer:
f(x) = x + 4
Step-by-step explanation:
Given
y - x - 4 = 0 ( add x to both sides )
y - 4 = x ( add 4 to both sides )
y = x + 4 ( let y = f(x) )
f(x) = x + 4
