Y - y1 = m(x - x1)
slope(m) = 1...because a parallel line will have the same slope
(1,-5)...x1 = 1 and y1 = -5
now we sub
y - (-5) = 1(x - 1) =
y + 5 = 1(x - 1) <== u could leave that first " one " out if u want...

Answer:

y+5=1(x-1)

Step-by-step explanation:

The point-slope form of a line is:

y-y_{1}=m(x-x_{1}); where y_{1} and x_{1} are the coordinates of a given point, and <em>m </em>is the slope.

In addition, when two line are parallel means that they both have the same slope. So, the point-slope form we have to find it's gonna have m=1, because is parallel to a line with that slope. Also, the given point is (1;-5).

Now, we just replace all values and isolate y:

y_{2}-y=m(x_{2}-x)\\y-(-5)=1(x-1)\\y+5=1x-1\\y=1x-1-5\\y=x-6

<h3>Therefore, the equation of the parallel line is:</h3>

y=x-6

<h3>And the point-slope form is:</h3>

y+5=1(x-1)

The height of the tunnel at the center is 54 ft, and the vertical clearance must be 18 ft at a point 8 ft from the center. Find
IrinaVladis [17]

the standard form for a horizontal ellipse is

X^2/a^2 + y^2/b^2 = 1

Substitute 54 for b and and use (8,18) as the

point to find a

x=8

y=18

8^2/a^2 + 18^2/54^2 =1

64/a^2 +  324/2916 = 1

324/2916 reduces to 1/9

64/a^2 + 1/9 = 1

64/a^2= 1-1/9

64/a^2 = 8/9

64*9/8 = a^2

576/8 = 72

A^2 = 72

A = square root(72) = 8.485

 So formula

would be x^2/72 + y^2/2916 =1

A car travels at 65 miles per hour. Going through collision,it travels at 3/5 this speed. Write this fraction as a decimal.
solniwko [45]

Answer:

0.6

Step-by-step explanation:

the car moves at a speed of 3/5*65 miles per hour

that is 39 miles per hour

but this has nothing to do with the question as the only fraction is 3/5
