Answer:

Option A is correct.

The constant of variation is, -\frac{3}{2}

Step-by-step explanation:

The Direct variation says that:

if a vary directly to b then, the equation is of the form: a = kb where k is the constant of variation.

Given: if y varies directly as x.

By definition of direct Variation:

y = kx  where is the constant of variation.

It is also given that: y = -3 and x =2

Solve for k;

-3 = 2k

Divide both sides by 2 we have;

k = -\frac{3}{2}

Therefore, the constant of variation is, -\frac{3}{2}

The figure is the combination of trapezoid and square. Then the area of the figure will be 39 square meters.

The complete question is attached below.

<h3>What is Geometry?</h3>

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

The figure is the combination of trapezoid and square.

Then the area of the geometry will be

Area = Area of trapezoid + Area of square

Area = 1/2 x (3 + 9) x 5 + 3 x 3

Area = 30 + 9

Area = 39 square meters

More about the geometry link is given below.

If the sales tax in Maple Town is 9.5%, how much would an ice cream of $4.25 cost with the tax added? Please explain.
faltersainse [42]
To find the sales tax, you need to find 9.5% of 4.25

4.25*.095 = <span>.40375

Now we need to add the sales tax to the price.

4.25 + </span>.40375 = <span>4.65375
Because dollars one have 2 decimal points we should round this to 4.65

Hope this helped!
