Answer:

Option C is correct

y = 15x

Step-by-step explanation:

Direct variation states that:

y \propto x          ......[1]

then, the equation is in the form of:

y=kx, where k is the constant of variation.

From the given table :

consider any points;

x = 9 and y = 135

Substitute these in [1] we have;

135 = 9k

Divide both sides by 9 we have;

15 = k

or

k = 15

then, the equation we have; y = 15x

Therefore,  the constant of proportionality for the table and write in the form y = kx is, y = 15x

Divide y by x:

150/10 = 15

135/9 = 15

30 /2 = 15

They all equal 15


This means the constant of proportionality would be y = 15x


The answer is C.

You have 50$ to spend at the carnival. First, you must pay $9.20 for an entrance ticket. Each snack costs $4.25, including tax.

What is the solution to the equation 12(x+5)=4x
lubasha [3.4K]

Answer:

-15/2 =x

Step-by-step explanation:

12(x+5)=4x

Distribute

12x +60 = 4x

Subtract 12x from each side

12x-12x +60 = 4x-12x

60 = -8x

Divide each side by -8

60/-8 = -8x/-8

15/-2 = x

-15/2 =x

A value to describe the steepness of a strainght line
marta [7]
That depends if the line is vertical or horizontal. If the line is vertical, the slope (steepness) of the line is undefined (this is because the x values across the entire line are the same). If the line is horizontal, the slope of the line is 0 (this is because the y values will always subtract to equal 0 when you use the form y1 - y2/x1 - x2 to find slope).

Hope this helps.

Will GIVE 200 Points!!! NEED HELP ASAP!!!! PLEASE HURRY AND HELP!!! For the given statement, write the converse, inverse, and co
UNO [17]

Answer:

See explanation

Step-by-step explanation:

Consider given statement "If a figure is a cube, then it has eight vertices" in math terms. Let

  • statement p be "A figure is cube.";
  • statement q be "A figure has 8 vertices."

Then the statement  "If a figure is a cube, then it has eight vertices"  can be written as

p\Rightarrow q

Converse (q\Rightarrow p): If a figure has eight vertices, then it is a cube.

Inverse (\neg p\Rightarrow \neg q): If a figure is not a cube, then it has not eight vertices.

Contrapositive (\neg q\Rightarrow \neg p): If a figure has not eight vertices, then it is not a cube.
