Step-by-step explanation:
(a)
For the graph to display direct proportion it must pass through the origin.
The graph shown does not pass through the origin thus does not represent direct proportion.
(b)
Given that q is directly proportional to r then the equation relating them is
q = kr ← k is the constant of proportion
To find k use the condition q = 76 when r = 20, thus
76 = 20k ( divide both sides by 20 )
3.8 = k
q = 3.8r ← equation of proportion
When r = 45, then
q = 3.8 × 45 = 171
-16-1x = -4x +8
add 1x to each side
-16 = -3x +8
subtract 8 from each side
-24 = -3x
divide both sides by -3
x = -24 / -3 = 8
x = 8
Answer:
n*-14 = 56
Step-by-step explanation:
56 / -14 = n
We can check our value for n by
n*-14 = 56
We must find the unit rate for each. Since frosted flakes is already given, we only need raisin brain.
13/1.4 = 9.29
9.29<11
Frosted flakes will be more sugary. Hope this helps!
