Write the standard form of this equation 2x +8+7/2y =0

Mathematics
1 answer:
Crank3 years ago
5 0

Answer:

4x + 7y = -16

Step-by-step explanation:

The standard form of a linear equation is Ax + By = C where A and B cannot be fractions and A is not negative. To write in standard form, clear the denominator by multiplying the equation by 2. Then move the constant to the other side of the equal sign using subtraction.

2x + 8 + 7/2y = 0

2(2x + 8 + 7/2y = 0)

4x + 16 + 7y = 0

4x + 7y = -16

We can use the Pythagorean theorem to solve for the perimeter of the kite.

a² + b² = c²

3² + 4² = UV²

9 + 16 = UV²

25 = UV²

√25 = √UV²

5 = UV

In the kite, adjacent sides are the same so UV = VW

3² + 9² = UX²

9 + 81 = UX²

90 = UX²

√90 = √UX²

9.49 ≈ UX or 3√10 ≈ UX

Now, add to find the perimeter.

5 + 5 + 9.49 + 9.49 or 5 + 5 + 3√10 + 3√10

28.98 or 10 + 6√10

Therefore, the perimeter is approximately 28.98 or 10 + 6√10

Best of Luck!
