Can I see the rest of the problem of number 18 please
P(x) = x^4 - 9x^2 - 4x + 12
P(1) = 1^4 - 9(1)^2 - 4(1) + 12 = 1 - 9 - 4 + 12 = 0
x = 1 is a root.
By dividing the polynomial by x - 1, gives other roots as 3 and -2
Answer: 2.127
Step-by-step explanation:
For this problem, we have to divide the number 212.7 by 100 cookies.
212.7 ÷ 100 = 2.127
So, each cookie will require 2.127 ounces of dough.
Y=7x+1
*note that the first number is always the x.
so,
a) (0,?)
y=7(0)+1
y=1
(0,1)
b) (3,?)
y=7(3)+1
y=21+1
y=22
(3,22)
