Step-by-step explanation:
Cross mutiply and x is equal to 3
Answer:
Step-by-step explanation:
(0, 3) (5, 1)
(1-3)/(5-0) = -2/5 is the slope
Answer: if i did this correctly its {x,y} = {3,6}
Step-by-step explanation:
y = x³ + 3x² - x - 3
0 = x³ + 3x² - x - 3
0 = x²(x) + x²(3) - 1(x) - 1(3)
0 = x²(x + 3) - 1(x + 3)
0 = (x² - 1)(x + 3)
0 = (x² + x - x - 1)(x + 3)
0 = (x(x) + x(1) - 1(x) - 1(1))(x + 3)
0 = (x(x + 1) - 1(x + 1))(x + 3)
0 = (x - 1)(x + 1)(x + 3)
0 = x - 1 or 0 = x + 1 or 0 = x + 3
+ 1 + 1 - 1 - 1 - 3 - 3
1 = x or -1 = x or -3 = x
Solution Set: {-3, -1, 1}
Hello,
I don't know the divison method but is it these one?
156.25= 625/4=(25/2)²
√156.25= 12.5
