Im confused what the question is...
Answer: D
Explanation:
x(x-9) = 0
=> x = 0
=> x-9 = 0
=> x = 9
The step which is INCORRECT is no other than the step 4 is incorrect because it shows the incorrect substitution. The step one is correct, the chosen point (2,5) is on the line, same with step 2 where the chosen point (1,3) is also in the chosen line. While step 3 is also correct where the line runs 1 unit rises 2 units such as slope m = 2/1. To make step 4 correct, we should substitute slope in step 3 in the equation below:
(y - y1) = m (x-x1) where m is the slope, in this problem m is 2/1
using point (1,3) and slope m=2/1, we have:
y - 3 = 2 (x - 1)
Thus, step 4 in Talia's solution is incorrect.
Well 10% is $6.50, so just multiple that by 2 and you get your fill tip of $13. Then you just add them together and you get $78.
