This equation can be solved graphically by plotting the equations
f(x) = 3^x
and
g(x) = 5x-1.
The x-coordinate of the point(s) of intersection is the solution.
_____
On my graphing calculator, I find it easier to locate x-intercepts, so I would rewrite the equation as
3^x -(5x -1) = 0
and plot the function
h(x) = 3^x -(5x -1)
The x-intercept(s) would be the solutions. (There are two: x≈0.577, x=2.)
Answer:
a = 12 units
Step-by-step explanation:
Equation given is
First we have to evaluate the powers.
= =
= =
So we can now write the equation again as:
Now we have to undo the addition,
Now we have to find the square root of to get the value of
or
But the length of a leg cannot be a negative value, so we can take the +12.
a = 12 units

<u><em>The complete question is</em></u>
The first three steps of completing the square to solve the quadratic equation x2 +4x -6= 0, are shown below.
Step 1: x2 +4x= 6
Step 2: x2 +4x+4=6+4
Step 3: (x +2)^2=10
What are the next 3 steps?
we have
step 4
Take square root both sides
step 5
Simplify
step 6
Solve for x
subtract 2 both sides
Answer:
4
Step-by-step explanation:
Here you find the greatest common factor of 16,20 and 24
The greatest common factor of a set of whole numbers is the largest positive integer that divides evenly into all numbers with no remainder.
Here, the G.C.F will be
16 20 24
2 8 10 12
2 4 5 6
2×2=4
Ax+by=c
y+4= -1/3(x-12)
remove ( )
y+4= -1/3x+4
subtract 4
y=-1/3x+0
add 1/3x
1/3x+y=0
hope this helps
