Y=3x+3
Perpendicular lines have the product of their gradients =-1
since gradient of line 1 =-1/3
then gradient of line 2 is
-1/3*m=-1
m=3
You divide 32 by 4 and it should be a whole number because 32 is a factor of 4 ....the answer is 8
Answer:
0.8X = Final cost
Step-by-step explanation:
Given that jeans are on sale for 20% off the regular price, to determine which function would give you the total cost for purchasing a pair of jeans that costs X dollars, the following calculation must be performed:
1X = Initial cost of the jeans
20% = 0.2
1 - 0.2 = 0.8
0.8X = Final cost
