For 49 It's 4*12 and 2*24 and 1*48 and for 64 it's 8*8 and 2*32
Answer:
First we add 7 on both sides
-7x+3y= -6.3
+7. +7
___________
then we simply
-7x + 7x= -1
bring down the 3y
-6.3+ 7x = 0.23
So, -1x+3y=0.7
2y = 0.7
___ __
2. 2
y = 0.35 or 35!!
Step-by-step explanation:
Hope this helps
Y = 3.5x
24= 3.5x
the train will be ride 6 times each day
and there are 7 days in a week
so multiply 6 and 7
=42
is the algebraic representation for an exponential function
Step-by-step explanation:
Given:
f(x + 1) = 4.f(x)
f(3) = 16
To Find:
Algebraic representation for an exponential function=?
Solution:
From the formula f(x+n) =
f(x)
when n= 1, x= 3
f(3+1)= 4(1)f(3)
f(4)= 4f(3)
Substituting the value of f(3)
f(4)= 4f(3)
f(4)= 4 x 16
f(4)= 64
f(4)=
f (5) =
x 16
f (5) =
x
f(5)= 
Similarly,
F(6) = 
Hence,
