Answer:

x = 5

Step-by-step explanation:

(3-6x)/3 = -11

first multiple both sides by 3

3 - 6x = -33

then subtract 3 from both sides

-6x = -30

then divide by 6

x = 5

Answer: x = 6

<u>Step-by-step explanation:</u>

(3-6x)/(3) = -11

3-6x = -33     [Multiply both sides by -3]

-6x = -36       [Subtract both sides by 3]

x=6               [Divide both sides by -6]

They are vertical angles. They are congruent. 

(2x+2)= (3x-52)

Add 52 to the other side. 

2x+54=3x

Subtract 2x on both sides.

54=x

I hope this helps!

A tunnel is in the shape of a parabola. The maximum height is 16 m and it is 16 m wide at the base, as shown below.
NeX [460]
Vertex at the origin and opening down → y=ax^2
Width: w=16
x=w/2→x=16/2→x=8
x=8, y=-16→y=ax^2→-16=a(8)^2→-16=a(64)→-16/64=a(64)/64→-1/4=a→a=-1/4

y=ax^2→y=-(1/4)x^2

7 m from the edge of the tunnel → x=w/2-7=8 m-7 m→x=1 m
x=1→y=-(1/4)x^2=-(1/4)(1)^2=-(1/4)(1)→y=-1/4

Vertical clearance: 16-1/4=16-0.25→Vertical clearance=15.75 m

Please, see the attached file.

Answer: Third option 15.75 m
