Step-by-step explanation:
33.3333% increase
simplify....
15:20
Calculate percentage change
from V1 = 15 to V2 = 20
(V2−V1) |V1| ×100
= (20−15) |15| ×100
= 515×100
= 0.333333×100
= 33.3333%change
= 33.3333%increase
It's an increase cuz your going up and not going down a number
Hope this helped a little!
(−4, 12), (1, −3)
y = −3x
x^2 −4 = y
so
x^2 −4 = −3x
x^2 + 3x - 4 = 0
(x + 4)(x - 1) = 0
x + 4 = 0; x = -4
x - 1 = 0; x = 1
when x = 1, y = -3(1) = -3
when x = -4, y = -3(-4) = 12
Answer
(-4 , 12), (1 , -3)
option d is correct
de=9 and ef=15
