Set the equations to equal each other because the angles are equal.
8x - 63 = 4x - 27
+63 on both sides
8x = 4x + 36
-4x on both sides
4x = 36
/4 on both sides

What is the equation of a line through point (-4,5) that is perpendicular to the line with equation y=-6x+4?
Jobisdone [24]
To find the gradient of the perpendicular line, we know that we must do the negative inverse of the current line's gradient

-6x from the old line will now be 1/6x

we are given points on that line and we therefore use the points and the new gradient to find the equation of the line using this formula

y-y1=m(x-x1) where m is the gradient

input the values that we have

y-5=1/6(x--4)

rearrange

y-5=1/6(x+4)
y-5=1/6x+4/6
6y-30=x+4
6y=x+34
y=1/6x+34/6
y=1/6x+17/3

navik [9.2K]

Answer:

d= 12.50 miles

Step-by-step explanation:

Kinematic equation of uniform motion (constant speed) :

v= d/t  Formula (1)

v: velocity in miles per hour (mph)

d: distance in miles

t: time in hours

Data

v= 50 mph

t= 0.25 hours

Problem development

We replace data in formula (1)

50 mph=d/0.25 hour

50 \frac{miles}{hour} = \frac{d}{0.25 hour}

d= 50\frac{miles}{hour} *0.25 hour

d= 12.5 miles

d= 12.50 miles

1 x 72 = 72

2 x 20 = 40

2 x 36 = 72

4 x 10 = 40

4 x 18 = 72

8 x 5 = 40
