It costs Luis 5 to park his car at a parking meter for two hours. What is the price to park for 1 hour? Draw a bar model or writ
maksim [4K]

Answer:

The cost of parking the car for 1 hour = $2.5

Step-by-step explanation:

Cost of parking car for two hours = $5

Now, let the cost of parking the car for one hour be $x

Since, the car is parked for two hours and the cost charged is $5

So, each hour the cost of parking is same ⇒ Cost of parking one hour is half the cost of parking the car for two hours.

Since, the cost of parking the car for one hour = $x

So, cost of parking the car for two hours = 2x

But this cost is given to be $5

⇒ 2x = 5

⇒ x = 2.5

Hence, The cost of parking the car for 1 hour = $2.5

Please answer this ASAP. The question is down below. Thank you!
Sonja [21]

Answer:

y = .5x^2 -2x -5

Step-by-step explanation:

Well we can start by seeing if the parabola is the same width by comparing it to its parent function ( y = x^2 )

In y = x^2 the 2nd lowest point is just up 1 and right 1 away from the vertex.

This is not true for our parabola.

So we can widen it by to the desidered width by making the x^2 into a .5x^2.

So far we’ve got y = .5x^2

Now the parabola y intercept is at -5.

So we can add a -5 into the equation making it.

y = .5x^2 - 5

Now for the x value.

So we can find the x value by seeing how far away the parabola is from from the y axis.

So the x value is -2x.

So the full equation is y = .5x^2 -2x -5

Look at the image below to compare.

What is 4c + 8c = -55 + 3c
Rzqust [24]

To solve this, you need to isolate/get the variable "c" by itself in the equation:

4c + 8c = -55 + 3c    You can first combine like terms (4c and 8c)

12c = -55 + 3c         Subtract 3c on both sides

9c = -55       Divide 9 on both sides

c=-\frac{55}{9}
