Two parallel lines are graphed on a coordinate plane. How many of the lines could represent proportional relationships?

Answers

Answer 1

Answer:
Not more than one of them could possibly represent a
proportional relationship.

A line that graphs a proportional relationship must go through
the origin (0, 0).

Either none or one of the parallel lines can go through the origin.

The only way that they can both go through the origin is
if they're both actually the same line.

You're phrasing it, so it shouldn't be much longer than the actual line. It should just be your interpretation.

Step-by-step explanation:

Mrs. Jacobs drove at a speed of 60 km/h to her mother's house 120 km away. She picked up a box of photos and drove back home at 40 km/h.Mrs. Jacobs thought to herself, "Well, I drove 60 km/h to get there, and 40 km/h to get home. I must have averaged 50 km/h for the whole trip."

Do you agree with Mrs. Jacob's conclusion? Why or why not?

Can someone please help me with the above problem? Thank you!

Answers

I know that you can't generally handle speed like that.

Without trying to go through a long-winded explanation,
let's just calculate her average speed for the whole trip
and see what it was.

Average speed = (distance covered) / (time to cover the distance).

-- On the way going to mother's house . . .

   Distance = 120 km.
   Time    = (120/60) = 2 hours.

-- On the way coming back from mother's house . . .

   Distance = the same 120 km
   Time = (120/50) = 2.4 hours.

Total distance covered = 240 km.
Time to cover the distance = (2 + 2.4) = 4.4 hours.

Average speed = (240 km) / (4.4 hours) = (54 and 6/11) km/hr .

That's why I don't agree with Mrs. Jacobs' conclusion.

4 hot dogs and a soft drink costs $6.30 whereas one hot dog in for soft drinks cost $4.20 what is the total cost of one hot dog and one soft drink?

Answers

Let h = hot dog
Let s = soft drink
4h + s = 6.30...Equation A
h + 4s = 4.20...Equation B

We have two equations in two unknowns. The unknowns are the variables h and s.
I will solve for s in Equation A by subtracting 4h from both sides.
s = -4h + 6.30
I will now replace s in Equation B with -4h + 6.30 to find the price of one hot dog.
h + 4(-4h + 6.30) = 4.20
h -16h + 25.2 = 4.20
-15h = -25.2 + 4.20
-15h = -21
Divide both sides by -15.
h = -21/-15
h = 21/15
h = 7/5
h = $1.40
We now know the value of one hot dog.
Go back to EITHER Equation A or B, replace h with 1.40, do the algebra and you will find the price of one soft drink.
