-8,-2
Step-by-step explanation:
F(x) = -4x^7 +x^3 -x^2 +5
a) It is a degree 7 polynomial, so will have 7 zeros (some may be repeated).
b) has 3 sign changes, so 1 or 3 positive real zeros. If odd powers have their signs reversed, the signs are changed to +--+, so there are 2 sign changes. There will be 0 or 2 negative real zeros.
____
There is actually 1 positive real zero and 0 negative real zeros. This means there are 3 conjugate pairs of complex zeros.
Answer:
1
Step-by-step explanation:
3x+2y=8
x=2y
3(2y)+2y=8
6y+2y=8
8y=8
y=1
x=2(1)
x=2
x-1=2-1
x-y=1
*I think you meant scientific notation.*
23 in scientific notation would be 2.3 x 10^1.
I think it’s the first option
