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
Answer:
The property used is the commutative property.
Step-by-step explanation:
In the commutative property, the sum is the same if you reorder the numbers.
I hope this helped! :-)
B. Identity Property of Addition
The Identity Property of Addition states that the sum of any number and zero will always be the first number. So -6 + 0 = -6 shows the Identity Property of Addition.
Answer: i think the answer is 320
Step-by-step explanation:
i say 320 because a square has 4 sides and there is 80 yards so all i did is multiply 80 x 4 = 320
