Answer:
y = -3x + 1
Step-by-step explanation:
Perpendicular lines have opposite reciprocal slopes, so the slope will be -3.
Plug in the slope and given point into y = mx + b
y = mx + b
-5 = -3(2) + b
-5 = -6 + b
1 = b
Then, plug in the slope and y intercept into y = mx + b again:
y = -3x + 1 will be the equation of the line
Answer:
Interest = $60.75
Amount = $510.75
Step-by-step explanation:
The formula for finding interest is;
Interest = Principal * Rate * Time
And here;
Principal = $450
Rate = 41/2% or 4.5%
Time = 3 years
Interest = 
Divided by 100 because of the percentage of the rate but here I made it 1000 because I moved the decimal point in the 4.5 forward once which means I have to add 0 to the denominator.
= 
= 
= $60.75
Now the amount is simply the Principal + Interest which will be;
= $450 + $60.75
= $510.75
Answer:
546
Step-by-step explanation:
4x3^7=2187
so now its
2187=4x+3
subtract 3 from both sides
now its
2184=4x
divide both sides by 4
546=x
This length of the rectangular field is 97 yards because if you double the length and double the width and add them up you get the perimeter (368)
