X+ y = 10
2x = 2y+4
2x/2 = 2/2y+4/2
x = y + 2
x+y = 10
y+2+y=10
2y + 2 = 10
2y +2-2 =10-2
2y = 8
2y/2 =8/2
y = 4
x + y =10
x + 4 =10
x +4-4 =10-4
x = 6
Check
2x = 2y +4
2(6) = 2(4) +4
12 = 8+4
12= 12
Answer:
x³ + 2x² - 19x - 20
Step-by-step explanation:
x + 1 = 0
x = -1
Substitute x = (-1) in the polynomial
x³ + 2x² - 19x - 20 = (-1)³ + 2*(-1)² - 19 *(-1) - 20
= -1 + 2 +19 - 20
= -1 - 20 + 2 + 19
= -21 + 21 = 0
So, (x + 10 ix a factor of x³ + 2x² -19x - 20
Answer:
Undefined
Step-by-step explanation:
if the line is like this __________________ then the slope is zero
