Answer:
x=-34
Step-by-step explanation:
isolate the variable by diving each side by the factors that don't contain a variable.
Answer:
From <u>fourth</u> month onwards, the growth rate of 
is greater than that of 
.
Step-by-step explanation:
Given:
The growth rates of both bank accounts are given as:
Now, as per question, we need to find the value of 'x' when the value of 
. Or,
Now, we can do this by checking the values of 'x' by hit and trial method.
Let 
. The inequality becomes:
Let 
. The inequality becomes:
Let 
. The inequality becomes:
Let 
. The inequality becomes:
Therefore, the value of 'x' for which is 4.
So, from the fourth month onwards, the balance in becomes greater than .
The graphical solution is shown below to support the same.
From the graph, we can conclude that after the 'x' value equals 3.4, the graph of lies above of . Hence, for 
<span><span><span>(<span>−<span>320x</span></span>)</span><span>(7)</span></span>16</span><span>=<span>−<span>140
The answer is -140
Hope this helps!

A line through two points A, B can be found by the point-slope form of the formula:
(y-ya)=m(x-xa)............(1)
and
m=(yb-ya)/(xb-xa).......(2)
where A(xa,ya), B(xb,yb) and m is the slope between points A & B.
Substituting
A(xa,ya)=A(1,3)
B(xb,yb)=B(0,2)
From (2)
m=(yb-ya)/(xb-xa)
=(2-3)/(0-1)
=-1/(-1)
=1
Substitute in (1) : (y-ya)=m(x-xa)
y-3=1(x-1)
Distribute and simplify
y=x-1+3=x+2
or
y=x+2 .................(3a) equation required in slope-intercept form
x-y+2=0...............(3b) equation in standard form
