Answer:
y = 
x - 
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
here m = , thus
y = x + c ← is the partial equation
to find c substitute (2, - 4) into the partial equation
- 4 = 
+ c ⇒ c = - 4 - = -
y = x - ← equation of line
Answer:
8 inches
Step-by-step explanation:
The surface area of a cone (without the base) is given by:
Surface area = pi*r*s
Where r is the base radius and s is the slant height.
The smaller cone has a surface area of 41.6pi in2 and a radius of 6.4 inches, so the slant height is:
41.6pi = pi*r*s
41.6 = 6.4s
s = 6.5 in
If the cones are similar, the radius and the slant height increase in the same proportion, so we have that:
r'/s' = r/s = 6.4/6.5
s' = r'*6.5/6.4
So for the larger cone, we have:
65pi = pi*r'*s'
65 = r'*r'*6.5/6.4
r'^2 = 64
r' = 8 inches
You cannot tell which number is greater just by the leftmost digits. This is because you do not know how many digits each number has. Ex: 80 and 3,000

1/2. It isn't asking for another solution, just the fraction.
Hope this helps!
