Step-by-step explanation:
The 1st equation is in slope-intercept form.
=> Slope = 4
The 2nd equation is in point-slope form.
=> Slope = -1/4
Since their slopes are unequal,
The lines are not parallel to each other.
However the product of their slopes is -1,
Therefore the lines are perpendicular to each other.
The answer is the 2nd option.
Answer:
60 mph
Step-by-step explanation:
I'm not sure if you meant 30 miles in half an hour, but if that's the case, your answer is 60 mph.
There are two halves in an hour so
30 x 2 = 60
Answer is C: 6/8
solve with square roots
Answer:
I want to it's the fourth one
Answer:
4 is not. (3 is)
