Answer:
x = 3,7
Step-by-step explanation:
x² - 10x + 21 = 0
x² - 7x - 3x + 21 = 0
x(x - 7) - 3(x - 7) = 0
(x - 3)(x - 7) = 0
x = 3, 7
Means the graph cuts the x-axis at 3 and 7
Answer:
(2,0)
Step-by-step explanation:
-1-1 = 2
-3+3=0
Taking x2 and x1 and y2 and y1 we have found our slope
85% of 36000 is 30600
9% of 30600 is 2754
30600 - 2754 = 27846
I'm fairly sure that's right, but I wouldn't say no to a second opinion
