Answer:
x1 = 2 -
x2= 2 +
Step-by-step explanation:
x/4 + 6 = 7 + 1/4x
(x^2 - 1)/4x = 1
x^2 - 1 = 4x
x^2 - 4x -1 = 0
x= (4+
)/2 = 2 -
x= 2 +
About 67 pairs. one shoe is left over. walking; 26 pairs running: about 41 pairs. sorry if im wrong
X intercept is 4/3 because you plug zeros in for y to find the y intercept
Gradient =2 because the slope is 2 units. Y-intercept = -2 because it crosses the y-line at -2.
Answer:
Graph B
The graph in the attached figure
Step-by-step explanation:
we have

This is a exponential function
of the form

where
a is the initial value
b is the base
r is the rate
b=1+r
In this problem
a=2 ----> the y-intercept
b=3
so
1+r=3 -----> r=3-1=2 -----> r=200%
so
The y-intercept of the graph is equal to 2
As x increases the value of f(x) increases
therefore
Graph B
