Answer:
y = -1/3x + 4
Step-by-step explanation:
Perpendicular line are opposite and reciprocal.
So I flip 3x to 1/3 and change both signs. negative to positive and positive to negative.
basically write the triangle in degree language like this is a acute angle because this is a 70* degree angle and talk more
Answer:
Each cupcake was $2.75
Step-by-step explanation:
We subtract the price of the ice cream from the total bill $22.26-$5.76=$16.50
We know he only bought the ice cream and cupcakes so once we subtracted the price of the ice cream, we now have the price of the cupcakes all together only
We divide the price of all the cupcakes by the amount of cupcakes to get the price of each individual cupcake $16.50/6=$2.75
Answer:
solid...(-3,0)(-4,-1)...shaded below the line
slope = (-1-0) / (-4-(-3) = -1/(-4 + 3) = -1/-1 = 1
y = mx + b
-1 = 1(-4) + b
-1 = -4 + b
-1 + 4 = b
3 = b
this line is : y < = x + 3 <== (thats less then or equal)
====================
solid...(1,1)(2,-1)...shaded below the line
slope = (-1-1) / (2-1) = -2/1 = -2
y = mx + b
1 = -2(1) + b
1 = -2 + b
1 + 2 = b
3 = b
