Answer:
5 1/2 or 5.5
Step-by-step explanation:
=8 1/2+2 1/6-5 2/12
=17/2+ 2 1/6-5 2/12
=17/2+13/6-5 2/12
=32/3- 5 2/12
=32/3-31/6
=11/2
=5 1/2
Answer:
3m
Step-by-step explanation: divide 12m by 4m
Answer:
y = -1/4x + 2.5
or
y = -1/4x + 5/2
Step-by-step explanation:
First we know that a perpendicular line is one that intersects at a 90-degree angle. This is simply the negative inverse of the slope in our case. So, 4 turns into -1/4 and that is our new slope. Next we know that we want it to pass through the point (6,1). Right now our equation is y = -1/4x + b. We can plug (6,1) into this equation and solve.
1 = -1/4(6) + b
1 = -6/4 + b
4/4 + 6/4 = 10/4
10/4 = b
simplify: 5/2 or 2.5 = b
Now we have our y-intercept, so we can complete our equation.
y = -1/4x + 2.5
or
y = -1/4x + 5/2
