Answer:
The demonstration is showed below
Step-by-step explanation:
The distance betwenn two points is given by:
If the point is equidistant from a point and a line, the distance must be equal. For the line let's select the point (x,-4), because the distance will be ortogonal, and is the small distance between a point and a line. So:
Removing the squares:
(x-2)² + y² = (y+4)²
(x-2)² + y² = y² + 8y + 16
y² - y² - 8y = 16 - (x-2)²
8y = (x-2)² - 16
y = (1/8)*(x-2)² - 16/8
y = (1/8)*(x-2)² - 2
ANSWER: D
REASON:
4(y x y) = 4(y^2) = 4y^2
Hope that helps!
Answer:
<h2> 5mile per hour</h2>
Step-by-step explanation:
Step one:
given data
distance= 1/4mile
time taken= 1/20 hour
Step two:
Required
speed
we know that speed is
speed= distance/time
substituting
speed= 1/4/1/20
speed=1/4*20/1
speeed=20/4
speed=5mile/hour
The option a sis correct, the speed is 5mile per hour

Answer:
x = -24
Step-by-step explanation:
First, distribute 2 to all terms within the parenthesis:
2(x + 11) =
2 * x = 2x
2 * 11 = 22
2x + 22 = -26
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operations, and stands for:
Parenthesis
Exponents (& Roots)
Multiplications
Divisions
Additions
Subtractions
~
First, subtract 22 from both sides of the equation:
2x + 22 (-22) = -26 (-22)
2x = -26 - 22
2x = -48
Next, divide 2 from both sides of the equation:
(2x)/2 = (-48)/2
x = -48/2
x = -24
x = -24 is your answer.
