X intercepts are when y = 0, set the equation equal to zero and solve:
0 = -x^3 +x^2 + x -1
-x^3 + x^2 = -x
-x + x = 0
0-1 = -1
The first one is (-1,0)
Because the equation contains squares the answer could also be opposite, so the other answer would be (1,0)
The two answers are (-1,0) (1,0)
Answer:
C
Step-by-step explanation:
The number of ribbon needs depends on the number of bows times 3 so
r= b x 3
Answer:
Step-by-step explanation:
in a right triangle a^2+b^2=c^2,
where a and b are the legs
where c is the hypothenuse
9^2= b^2+3^2
81-9=b^2
b^2=72
b=8.48
