Answer:
y = - 
Step-by-step explanation:
Given y varies inversely with x then the equation relating them is
y =
← k is the constant of variation
To find k use the condition y = 7 when x = - 4, then
7 =
( multiply both sides by - 4 )
- 28 = k
y =
← equation of variation
When x = 5 , then
y =
= - 
Answer:
B is the answer to your question!
Consider one pyramid
Side length of base = 1.5cm and its height is 1 cm
Slant height of one of the lateral faces = sqrt(1^2 + 0.75^2) = 1.25 cm
Area of one of the triangular faces = 0.5 * 1.5* 1.25 = 0.9375 cm^2
There are 8 of these so the required surface area = 8 * 0.9375
= 7.5 cm^2 Answer
Answer:
12
Step-by-step explanation:


When F = 18; d = 2


Cross multiply;
18 x 4 = K
72 = K
There the equation connecting F and
is

Now, Find F when d = 6
All you do is to substitute d = 6 in to 

Therefore;
F = 12
Please mark me brainiest if correct.
