Answer:
a) 18 grapefruits
b) 6 grapefruits
Step-by-step explanation:
a) n = 14.4 / 0.80 = 18 grapefruits
b) n = (14.4 / 3) / 0.8 = 6 grapefruits
Given:
The function is

(-5,n) is an ordered pair of the function rule.
To find:
The value of n.
Solution:
If (-5,n) is an ordered pair of the function rule, then the function must be satisfied by the point (-5,n). It means f(-5)=n.
Substitute x=-5 in the given function.



We know that,
. So,

Therefore, the value of n is 10.
f(-10) = 4
f(-2) = 4
Since y is constant while x isnt we just dont need to put x
f(x) = 4

Answer:
no, y does not vary directly with x
Step-by-step explanation:
If there is direct variation, the constant of variation can be found as ...
k = y/x
Here, those ratios are ...
y/x = 6/3 = 2
y/x = 18/6 = 3
y/x = 24/8 = 3
The ratio of y to x is NOT A CONSTANT, so <em>there is no direct variation.</em>
