Y intercept occurs when x = 0
so its 0-4 / 0- 4 = 1
coordinates of y intercept is (0,1)
x intercept occurs when y = 0
(x -4) / (x^2-4) = 0
x-4 = 0
x = 4
x intercept at (4,0)

175 divided by 17 plus 8, use PEMDAS
Answer:
Q6. D
Q8. A
Step-by-step explanation:
Q6. In 40 trials, he flipped '2 heads and 1 tail' 16 times.
For 2 heads, probability= 16/40= 4/10
For 120 trials, number of times= 4/10 × 120= 48
Q8.

Answer is A because the inequality shows that x is equal or greater than 8 so the dot at 8 has to be coloured.
Note that we do not change the inequality sign unless we are dividing the whole thing by -1.
