Answer:

  B.  0

Step-by-step explanation:

If you subtract the right side expression and simplify, you get ...

  4/5(20x +5) -(16x -2) = 0

  16x +4 -16x +2 = 0

  6 = 0 . . . . . . . . . . . . false

There is no value of x that will make this true. There are no solutions.

kirill115 [55]

Answer: y=11x-2


Step-by-step explanation:

1. By definition, the equation of the line has the following form:

y=mx+b

Where <em>m</em> is the slope and <em>b</em> is the y-intercept.

2. Keeping the information above on mind, you the problem says that the slope is 11 and the y-interecept is -2, then:

m=11\\b=-2

3. Substitute these values into the equation of the line and you obtain that the equation of that line is:

y=11x-2

A camper attaches a rope from the top of her tent, 4 feet above the ground, to give it more support. If the rope is 8 feet long,
irina [24]
Using the Pythagorean theorem  4 would be the height and 8 would be the hypotenuse, you need to find the base

4^2 + X^2 = 8^2

16 x x^2 = 64

x^2 = 64-16
x^2 = 48

x = sqrt(48) = 6.92 feet ( round answer as needed )
