Dalton and Connor each invest money. The function f(x) = 850(1.07)^x models the value of Dalton's account after x years. The function g(x) = 844(1.06)^x models the value of Connor's account after x years. What is the difference between the percentage points of the two
annual interest rates?

A. 4%
B. 6%
C. 7%
D. 1%

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.

=

x=0.8898305 is the answer to that equation

4 inches will get you 10.16 centimeters, but you can either do 10.1 or round up to 10.2. good luck and hope this : )
