Answer:

k = 5,

y = 5x

Step-by-step explanation:

If y is proportional to x,

y ∝ x

Then the equation will be

y = kx

Her k = proportionality constant.

Now we choose a point from the given table.

Let the point is (2, 10).

By putting the values of x and y in the equation,

10 = 2×k

k = \frac{10}{2}

k = 5

This will be true for any point we choose from the table.

And the equation will be y = 5x

KiRa [710]

Answer:

The perimeter of the isosceles triangle is 32 centimeters

Step-by-step explanation:

<em>The perimeter of any figure is </em><em>the sum of the lengths of outline sides</em>

Let us use this fact to solve our question

∵ The perimeter of the triangle is the sum of the lengths of its 3 sides

∵ The triangle is an isosceles triangle

∵ The length of each two equal sides is 12 centimeters

∵ The length of the third side is 8 centimeters

→ Add the lengths of the 3 sides

∴ The perimeter of the triangle = 12 + 12 + 8

∴ The perimeter of the triangle = 32 centimeters

∴ The perimeter of the isosceles triangle is 32 centimeters
