Answer:
y = -x/6 + 17
Step-by-step explanation:
Step 1: find the slope
y = 6x - 1
Equation of a line is
y = mx + c.
m - slope
m = 6
Note : if two lines are perpendicular to the other, both lines are negative reciprocal of each other
m = -1/6
Step 2 : using a point slope form equation
y - y1 = m( x - x1)
( -6 , 18)
x1 = -6
y1 = 18
y - 18 = -1/6(x - (-6)
y - 18 = -1/6( x + 6)
y - 18 = -x - 6 / 6
y = (-x - 6)/6 + 18
LCM = 6
y = (-x - 6 + 108)/6
y = -x + 102 / 6
y = -x/6 + 102/6
y = -x/6 + 17
The equation of the line is
y = -x/6 + 17
Answer:
4.) y=x-16
Step-by-step explanation:
Here,
y=4,
x=20
Now,
putting the value of x and y.
or, 4=20-16
or, 4+16=20
∴20=20
Answer:
V = 115.5 cubic yards
Step-by-step explanation:
V (cone) = 1/3πr²h
just substitute given values to get:
r = 7/2 or 3.5
h = 9
V = π(3.5²)(9)/3
V = 115.5 cubic yards
The corresponding sides of the model and the actual bridge are in proportion because the two solids are similar.
The scale factor from the model to the actual bridge is 5/25 = 6/30 = 8/40 = 1/5.
Answer: 1/5
