Answer:
y = -3x +6
Step-by-step explanation:
The perpendicular line will have the coefficients of x and y swapped (and one of them negated), and will have a constant appropriate to the point the line needs to go through.
The equation will look like ...
x -3y = 3 . . . . . . . . . . . . . given line
3x +y = constant . . . . . . perpendicular line
where "constant" can be found by substituting for x and y.
3x +y = 3(5) +(-9)
3x +y = 6 . . . . equation in standard form
To put this in slope-intercept form subtract 3x:
y = -3x +6
The answer is B because 3600 divided by 40 is ninety
Answer:
12.5 mph
Step-by-step explanation:
50 miles / 4 hours=
25 miles / 2 hours=
12.5 mph
X=-3
because
-4x=21-9
-4x= 12 divide both sides
x=-3
