Step-by-step explanation:
we start first by finding the gradient of the line
change in y/change in x
7-(-1)/3-7=8/-4
=-2
then for perpendicular lines m1m2=-1
therefore to find the gradient of that line
-2m2=-1
therefore m2=2
so therefore
y-5/x-3=2
so y-5=2x-6
y-2x=-1
in the form y= mx +c
then y=2x-1
Answer:
$55.55
Step-by-step explanation:
To find the cost of the purchase add 4 times the cost of one large sack to the cost of one small sack:
4($11.55) +($9.35) = $46.20 + 9.35 = $55.55
The cost of 4 large sacks and 1 small sack would be $55.55.
