<h3><u>The value of the greater number is 15.</u></h3><h3><u>The value of the smaller number is 7.</u></h3>

x = 2y + 1

3x = 5y + 10

Because we have a value for x we can plug this value in to find the value of y.

3(2y + 1) = 5y + 10

Distributive property.

6y + 3 = 5y + 10

Subtract 5y from both sides.

y + 3 = 10

Subtract 3 from both sides.

y = 7

We can plug this value back into the original equation to find the value of x.

x = 2(7) + 1

x = 15

0.6w = 0.48 how u do this
vovangra [49]

A variable next to any number means to multiply, so we would do the inverse operation -- We would divide 0.48 by 0.6, which is 0.8. Therefore, W=0.48. To check your work, multiply 0.6 by 0.8, and what do you know? It's 0.48! :)

The polynomial of degree 3, P(x), has a root of multiplicity 2 at x = 3 and a root of multiplicity 1 at x = – 3. The y-intercer
grigory [225]

9514 1404 393

Answer:

  P(x) = -1/2(x -3)²(x +3)

Step-by-step explanation:

When q is a root of the polynomial, (x-q) is a factor. This polynomial will be ...

  P(x) = a(x -3)²(x +3)

For x=0, the y-intercept will be ...

  P(0) = 27a = -13.5

Then the value of a is ...

  a = -13.5/27 = -1/2

The formula for P(x) is ...

  P(x) = -1/2(x -3)²(x +3) . . . . . . factored form

  P(x) = -0.5x³ +1.5x² +4.5x -13.5 . . . . standard form

A 12-foot cable attached to the top of the mast of a sailboat is fastened to a point on the deck 4 feet from the base of the mas
Vilka [71]

Answer:

The height of the mast is 8√2 feet

Step-by-step explanation:

In this question, we are asked to calculate the height of the mast given the information in the question.

Please check the attachment for diagrammatic representation.

From the diagrammatic representation, we can conclude that we are asked to calculate the value of the third side of a right angled triangle, given the length of the two other sides.

Using the pythagoras’s theorem;

Square of hypotenuse = square of opposite + square of adjacent

From the diagram, we can see that the length of the cable represents the hypotenuse.

Hence;

AB^2= BC^2 + AC^2

12^2 = 4^2 + AC^2

144 = 16 + AC^2

AC^2 = 144 - 16

AC^2 = 128

AC = √128

AC = 8√2 feet
