Answer:
Decreased by 20%.
16 lbs is 80% of 20 lbs.
Step-by-step explanation:

y × 20 = 16 × 100
20y = 1600
20y ÷ 20 = 1600 ÷ 20
y = 80
100% - 80% = 20%
I can’t answer it without a picture of the graph
Answer:
You are clicking on graphs.
However, you should sketch a graph of your function to see what the correct one looks like.
Create a table containing a few values of x and y
I chose x = -4, -2, 0, 2, 4.
Draw your axes
Plot your points
Draw the graph
Your graph should look like the one below.
Step-by-step explanation:
La forma estándar de una ecuación de un círculo es% 28x-h% 29% 5E2 +% 2B +% 28y-k% 29% 5E2 + = + r% 5E2
donde Pt (h, k) es el centro y r es el radio
x ^ 2 + y ^ 2-10x + 4y + 4 = 0
completando los cuadrados para ponerlos en la forma estándar
x ^ 2 -10x + y ^ 2 + 4y + 4 = 0
(x-5) ^ 2-25 + (y +2) ^ 2-4 + 4 = 0
(x-5) ^ 2 + (y + 2) ^ 2 = 25
El centro es (5, -2) radio = 5
