2x-4y+7=0 how do I find the slope for this?

Digiron [165]

Answer:

The slope is 1/2 and the y intercept is 7/4

Step-by-step explanation:

2x-4y+7=0

To find the slope, we need to put the equation in slope intercept form

y = mx+b

So we need to solve for y

Subtract 2x from each side

2x-2x-4y+7=0-2x

-4y +7 = -2x

Subtract -7

-4y+7-7 = -2x-7

-4y = -2x-7

Divide by -4

-4y/-4 = -2x/-4 -7/-4

y = 1/2 x +7/4

The slope is 1/2 and the y intercept is 7/4

What area of the grass is being watered by this sprinkler

Novay_Z [31]

<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷ Use this formula:

Area of circle = $\pi r^{2}$

However, as we are using 3.14 for 'pi', we can write it like this:

Area = $(3.14)r^{2}$

'r' is the radius which is 12ft

Substitute this value into the equation:

Area = $(3.14)12^{2}$

Solve:

Area = 452.16

Multiply this value by 0.75 to get the answer:

452.16 x 0.75 = 339.12

339.12 square feet is being watered

An insured has $5,000 of medical coverage on a personal auto policy at the time of a covered accident. The insured and two passe

Vlad1618 [11]

Answer: 14,000 $ Max will be paid and 5000$ per person.

Step-by-step explanation:

In this case, we can assume the following:

1. That the policy covers only the insured one and not the passengers

2. The policy cover all the injured.

Now, the policy covers 5000$ of medical treatment, so, the medical treatment for the insured is 7000$.

To this quantity you'll have to take out the policy coverage which is 5000$, so: 7000 - 5000 = 2000$.

Finally, we just have to to the sum, of all quantity, because the passengers are not included in the policy, therefore:

8000 + 4000 + 2000 = 14000 $.

That is the maximum paid of all, and 5000$ will pay the policy for the injured only.

Now, if we assume that the passengers are also covered by the policy, then:

7000 - 5000 = 2000

8000 - 5000 = 3000

4000 - 5000 = -1000 it won t pay anything.

So if we sum 5000 + 5000 + 4000 = 14000$.

We got the same result assuming the policy with all.

Therefore the final answer is that the policy will pay 14000$ for all.
