Answer:
y = 9
Step-by-step explanation:
Given y is directly proportional to (x - 1)² then the equation relating them is
y = k(x - 1)² ← k is the constant of proportionality
To find k use the condition x = 5 when y = 4
k = = = = , thus
y = (x - 1)² ← equation of proportion
When x = 7, then
y = × 6² = × 36 = 9
So Janie has 4 pizza.
How many individual slice can be served if they are right angles.
Now a right angle is 90 degrees and looks like this
l
l
l______
Now if we are talking a pizza in the shape of a circle
A circle is 360 degrees around
This means we can fit 4, 90 degree right angles into 1 pizza.
So doing this math. 4, 90 degree pieces per pizza
And 4 pizzas
4 x 4 = 16
16 right angle slices can we served
Hope this helps!

1 ton=2000lb
total weight=2000
we want total weight=weight of cans
weight of cans=weight of 1 can times number of cans
W of cans=1/25c
total weight=weight of cans
2000=1/25c
times 25/1 both sides
50000=c
50,000 cans
