Answer:
Identity property.
Step-by-step explanation:
Any number added to 0 keeps its original value, keeping its identity.
Answer:
y = -2x - 5
Step-by-step explanation:
Set the slope of the given equation to the reciprocal to get a perpendicular slope:
y = 1/2x --> -2x
y = -2x + b will be your current equation. To get b, you must insert the given information: (-1, -3)
-3 = -2 (-1) + b
Solve:
-3 = 2 + b
<u>-2 -2 </u>
-5 = b
Thus your equation would be y = -2x - 5.
Y= 8x would be the equation as in mx+b, mx equals the slope (8/1 = 8) and b equals the y intercept which is 0.
Answer: rs 4800, rs 3456
Step-by-step explanation:j
given data:
length of a sid = 48m
cost of ploughing the field = rs 25/m
cost of fencing the field = rs 18/m
solution:
we know a square has four equal sides. so total length of the field is
= m ( 48 + 48 +48 + 48 )
= 192m
cost of ploughing the field
= 192m * rs 25
= rs 4800
cos of fencing the field
= 192m * rs 18
= rs 3456
