Slope= y2-y1/x2-x1
so
slope=9-7/7-9
slope=-1
Neither
yiu could always use a program like geogebra
or count the gradient
if gradien is equal that the lines are parallel, if -1 than perpendicular
Answer:
The answer is option A
The x-intercepts are (–12, 0) and (–6, 0). The y-intercept is (0, 72). The vertex is an absolute minimum, (–9, –9).
Hope this helps.
Answer:
1. and III.
Step-by-step explanation:
Option 1 and 3 are correct.
The probability of landing on heads would be 1/2, so 50 times in 100. This is the expected outcome, so option 1 is correct.
However, that is just the most probable outcome, probability is almost never 100% accurate. Therefore, the number of heads will most likely be 50, give or take 5 or so. Therefore, option 3 is also correct.
