First to get the equation you knew to understand one thing about perpendicular lines. The slope of the line is the opposite reciprocal of the perpendicular lines or the new slope is m = 10.
Then you use the formula
y = mx + b
you plug in your values from the point and the new slope.
(1,5) with new slope m
5= 10(1)+b
5-10=b
-5 = b
then make your new equation
y = 10x -5
that's your line that goes through point (1,5) and is perpendicular to the line given
It cannot be simplified more than that. hope this helps!
The answer is 42.80 , 2.28 is what they saved and i got the .80 cents because i rounded up from .78
Answer:
Marco's boxes weigh 15 lbs.
Step-by-step explanation:
9x + 14(x - 8) = 233
9x + 14x - 112 = 233
23x = 345
x = 15
