Answer:
x = -1 or 2
Step-by-step explanation:
Taking the antilog, you have the quadratic ...
x^2 -x -1 = 1
x^2 -x -2 = 0 . . . . subtract 1
(x -2)(x +1) = 0 . . . factor
The values of x that make these factors zero are the solutions to the equation.
x = 2 or x = -1
(fog) (x) = (5x - 7) / (5x - 4)
The denominator cannot be zero so the domain is All real x except x = 4/5
The formula for the circumference of a circle is 2πr. r stands for the radius ehich is 1/2 of the diameter (the length from one edge of the circle to another on the inside of the circle). If you are estimating then you will want to change π to three and put that in for pie in the original equation.
Answer:
$1559.40
Step-by-step explanation:
1. Find the perimeter of the garden

2. Convert to feet
1 yd = 3ft
50 x 3 = 150
50 yd = 150 ft
3. Divide by 2.5 to find out how many sections are needed
150/2.5 = 60 sections
4. Multiply by 25.99
60 x 25.99 = 1559.4
It will cost $1559.40
Answer:
10*5 = 7x
Step-by-step explanation:
We can solve using cross products
10*5 = 7x
50 = 7x
divide each side by 7
50/7 =7x/7
50/7 =x
