Y α 1/x
y = k/x Where k is the constant of proportionality.
xy = k Cross Multiplying.
k = xy
Recall y= -8 when x = -9
k = -9 * -8 = 72
Finding y when x = 4.
k = xy
72 = 4y Divide both sides by 4.
y = 72/4 = 18.
y = 18.
V= 5 x 4^2 + 5 x 4
V= 5 x 16 + 20
V= 80+ 20
V= 100
Answer is C 100 cubic units
Answer:
x · -4
Step-by-step explanation:
-2×-4=8
8×-4=-32
-32×-4=128
Answer:
11
Step-by-step explanation:
(Note that the diagram is not to scale)
You know BC is 6
You know DC is 5
You know CE is 12
Using K's position, it shows that AC is one off from EC
AC=11
