Answer:
a=1 is the answer
Step-by-step explanation:
let
p(x)=x³-2ax²+16
put x= -2
p(-2)=(-2)³-2a(-2)²+16
p(-2)=-8+16-8a
p(-2)=8-8a
as (x+2) is a factor of p(x) then p(x) is equal to zero
8-8a=0
8=8a
a=1
i hope this will help you
Answer:
Dilation
Step-by-step explanation:
Dilation can only be used to prove that certain figures are similar
Answer:
Step-by-step explanation:
y = mx + b
m = delta y / delta x
m = (-13 - 3) / [(9 - (-3)]
m = -16/12
m = -4/3
From (-3 | 3) we know that when x = -3, y = 3
Placing into equation to find b
3 = (-4/3)*-3 + b
3 = 12/3 + b
b = -1
