Answer:
x=7
Step-by-step explanation:
y=mx
5.5=m×11
5.5÷11=m
m=1/2
y=mx
3.5=1/2×x
3.5÷1/2=x
x=7
Answer:
The slope-intercept form is 
Step-by-step explanation:
To find the slope, use

Replace the x and y values with the points.

Solve.


After that, find the y-intercept form.
Put the equation in point-slope form.

Replace x with 0.


Add 5 to both sides.

Convert to improper fraction form.
The y-intercept is 
Now finally, write in slope-intercept form. (y=mx+b)
m is slope, b is the y-intercept.
Given:
Inner cone: diameter = 12 cm ; height = 6 cm
Outer layer: diameter = 12 cm ; height = 15 cm
Volume of a cone = π r² h/3
Inner cone: V = 3.14 * (6cm)² * 6cm/3 = 3.14 * 36cm² * 2cm = 226.08 cm³
Outer layer: V = 3.14 * (6cm)² * 15cm/3 = 3.14 * 36cm² * 5cm = 565.20 cm³
Volume of Outer layer : 565.20 cm³
less: Volume of inner layer:<u> 226.08 cm³</u>
Volume of cream filling: 339.12 cm³
