Y = -x + 10 and y = 2x + 4

X=2, y=8

Step-by-step explanation:

Y=-x+10 equation 1

y=2x+4 equation 2

-x+10=2x+4. Substitute y of first equation into 2nd equation

-x-2x+10=4

-3x=4-10

-3x=-6

x=2

solve for y by inserting x value into either equation

y=-x+10

y=-2+10

y=8

check answer

y=2x+4

8=2(2)+4

8=4+4

8=8

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

168

step-by-step explanation:

i am pretty sure that the answer is 168
