Answer:
Step-by-step explanation:
The formula governing this situation is
m1 * m2 = - 1
Method One
So let m1 = 7/4
(7/4)*m2 = - 1 Multiply by 4
7*m2 = -1*4 Divide by 7
m2 = -4/7
Method Two
Most people teaching this try to get you to use reciprocals. If you know how to do that then the answer is much simpler.
7/4 m2 = -1 Multiply by 4/7
4/7 * 7/4*m2 = - 1 * 4/7
m2 = -4/7
However if you are not comfortable with reciprocals, then then the thing to do is to handle them the way I showed you in the first method.

Answer:
2400
Step-by-step explanation:
x+y+z=147
x+(x+1)+(x+2)=147
3x+3=147
3x=144
x=48
The three consecutive positive numbers are 48, 49, and 50.
48 • 50 = 2400
slope = (y2-y1)/(x2-x1)
m = (33-5)/(11-4)
m=28/7
m=4
slope = 4
Answer: X= 68
