Answer:
y=-1/2x-1/2
Step-by-step explanation:
For this, you need to use the point slope formula, (y-y1)=m(x-x1). The slope, m, would be -1/2 since the line we're looking for is perpendicular (meaning the slope is the negative reciprocal of the original slope). The x1 would be 3, and the y1 would be 1.
(y-y1)=m(x-x1)
(y-1)=-1/2(x-3)
y-1=-1/2x-3/2
y=-1/2x-1/2
Let one piece of the rope be x
Let the other piece of rope be x + 5
These two pieces put together will make 20 feet.
So we say:
x + (x +5) = 20
What is x? We expand the equation.
x + x + 5 = 20
x + x = 20 - 5
2x = 15
x = 7.5
The shorter piece is therefore 7.5 feet.
The longer piece is 7.5 + 5 = 12.5 feet.
The answer is a) -20 you can go and rule out d.e,f
Answer:
1. Shen payed around $2.06 for the first bag of dog food.
2. Shen payed around $2.21 for the second bag of dog food.
Step-by-step explanation:
First, you have to do 14.98/7.26 to get around 2.06
Then, you do 17.54/7.94 to get around 2.21
Hope this helps!
