C

Using Descartes' rule of signs

look for the number of sign changes in f(x)

+ / + / - / -

There is 1 sign change hence 1 positive zero

f(-x) = -x³ + x² + 8x - 8

look for the number of sign changes in f(- x)

- / + / + / -

there are 2 sign changes hence 2 possible negative zeros

Solve the system by substitution 5x+y=-10. 4x-7y=-8
storchak [24]

Answer:

x = -2 and y = 0

Step-by-step explanation:

5x + y = -10

4x - 7y = -8

Rearrange the first equation to equal y.

5x + y = -10

y = -10 - 5x

Replace y in the second equation with the first equation.

4x - 7y = -8

4x - 7(-10 - 5x) = -8

4x - (-70 -35x) = -8

4x + 70 + 35x = -8

Rearrange the equation to find x.

4x + 35x = -8 - 70

39x = -78

x = -2

Now that you know x, use the rearranged first equation to find y.

y = -10 - 5x

y = -10 - 5(-2)

y = -10 + 10

y = 0
