Luke: 2 miles in 40 minutes, 20 minutes a mile, (2/40 = 20 minutes a mile)
Luke's speed is 3 miles an hour (60minutes/20minutes a mile = 3miles).
Sally: 0.05 miles a minute, 60 minutes in an hour, 60 x 0.05 = 3 miles an hour. Or 0.05 miles a minute, 40 minutes walked, 40 x 0.05 = 2 miles walked.
There are a few other ways to show that they are accurate rates.
So yes, they are both correct rates.
First find out how much she spent on the fabric. That's 12.5 yards times 4.50 a yard which is $56.25. Now figure out how many beds she can make with 12.5 yards if each bed uses 2.5 yards of fabric by dividing 12.5 by 2.5 to get 5 beds. She can make 5 beds for $56.25. If she sells each of those 5 beds for $17.50 each, she makes 5 times $17.50 which is $87.50. If she spent $56.25, subtract that from what she makes: 87.50 - 56.25 = 31.25
yes.
yes
yes.
see if it worked good luck bro
Answer:
x=-2
Step-by-step explanation:
Given points are (-2,2) and (-2,-3).
Now we need to find equation of the line passing through the given points.
So let's begin by finding slope
![m=\frac{\left(y_2-y_1\right)}{\left(x_2-x_1\right)}=\frac{\left(-3-2\right)}{\left(-2-\left(-2\right)\right)}=\frac{\left(-5\right)}{\left(-2+2\right)}=-\frac{5}{0}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B%5Cleft%28y_2-y_1%5Cright%29%7D%7B%5Cleft%28x_2-x_1%5Cright%29%7D%3D%5Cfrac%7B%5Cleft%28-3-2%5Cright%29%7D%7B%5Cleft%28-2-%5Cleft%28-2%5Cright%29%5Cright%29%7D%3D%5Cfrac%7B%5Cleft%28-5%5Cright%29%7D%7B%5Cleft%28-2%2B2%5Cright%29%7D%3D-%5Cfrac%7B5%7D%7B0%7D)
which is undefined. That means graph of the line must be vertical as you can see that in given points, x-value is not changing.
Equation of vertical line is given by x=k where k is the fixed value of x-coordinate.
x-coordinate is -2 in given points.
Hence final equation is x=-2.
