Answer:
y= -1/3(x) + 8
Step-by-step explanation:
slope of the 1st line = 3
slope of the line perpendicular to the first is its opposite reciprocal, so
slope of the 2nd line = -1/3
now we have a point and the slope of the perpendicular line, so we use the point slope formula to get:
y-7=-1/3(x-3)
y= -1/3(x) + 1 + 7
y= -1/3(x) + 8
X-54
Y- 36
180-126 to find x
And 54+ y= 90
It costs $.50 to mail a letter of that size.
All letters that are under 3.5 oz take only one stamp to ship. Since 2.7 is less, it would cost only $.50
f(x) is a function of x. To find f(-2), plug in the value of x=-2.
The answer is -2.
