<span>(A) formulate an equation for x: A$100= S$(65-5) So A$100= S$(60) So A($100)/60 = S$(60)/60 THEN A(1.66)= S$(1) (B) find the value of x: (By the previous equation provided x = ((A$100)/(S$))+5 (C) find the amount of Singapore dollars mr neo received if he exchanged A$125 in November 2013: IF A$(1.66)=S$(1) then A$(1.66x125)= S$(207.50) Thank you!</span>
Answer:
(f(x) -f(a))/(x -a) = x +a +1
Step-by-step explanation:
(f(x) -f(a))/(x -a) = ((x^2 +x +5) -(a^2 +a +5))/(x -a) = (x^2 -a^2 +x -a)/(x -a)
= ((x -a)(x +a) +(x -a))/(x -a) = x +a +1
(f(x) -f(a))/(x -a) = x +a +1
Answer:
x=8
Step-by-step explanation:
p=(l+b)
140=2(x+4x-2)
140=2(9x-2)
140=18x-4
140+4=18x
144=18x
144/18=x
8=x

Answer:
Step-by-step explanation:
we know that
A quadratic function in factored form is equal to
where
a is the leading coefficient
x_1 and x_2 are the zeroes of the function
substitute the given values
Find the value of a
Remember that
For x=0 ----> f(0)=4
substitute
so
