5 0

Answer:

<h2>x=2 , x = 6</h2>

Step-by-step explanation:

x² – 8x = 20 ⇌ x² – 2(4)x  = 4 + 16 ⇌ x² – 2(4)x - 16 = 4 ⇌ (x - 4)² = 4

⇌ x - 4 = 2 or x - 4 = -2 ⇌ x = 6 or x = 2

What is the height in meters of a person who is 6 ft 1.0 in. tall? (assume that 1 meter equals 39.37 in.)?

1 foot = 12 inch so 6 feet = 6*12 inch
6 feet = 72 inch

The height of the person in inch is = 72+1 = 73 inch

1 meter.............39.37 in

x = 73/39.37 = 1.85 meters

Really need help with this plsss answer
Nutka1998 [239]
Point slope form is:

y - y_{1} = m(x - x_{1})

With y_{1} and x_{1} being the coordinate points, and m being the slope.

So the coordinate points are (4, -5), and the slope is -6 in this case.

So just substitute everything in, to get:

y - ( -5) = -6(x - 4)

Or

y + 5 = -6 (x - 4)
