Answer:

Option D $y\leq -3x-3$ and $y$

Step-by-step explanation:

step 1

Find the equation of the inequality A

we know that

The solution of the inequality A (dashed line) is the shaded area below the dashed line

The equation of the dashed line is $y=-\frac{1}{2}x+2$

therefore

The equation of the inequality A is $y$

step 2

Find the equation of the inequality B

we know that

The solution of the inequality B (solid line) is the shaded area below the solid line

The equation of the solid line is $y=-3x-3$

therefore

The equation of the inequality B is $y\leq -3x-3$

The system of linear inequalities is

$y\leq -3x-3$ and $y$

The perimeter of a rectangular swimming pool is 160 feet . The length of the swimming pool is four times its width. Find the dim

Murrr4er [49]

Formula for Perimeter of Rectangle:

P = 2(L + W)

Plug in 160:

160 = 2(L + W)

L = 4W
So we can plug in '4W' for 'L' in the first equation.
160 = 2(L + W)

160 = 2(4W + W)

Combine like terms:

160 = 2(5W)

160 = 10W

Divide 10 to both sides:

W = 16

Now we can plug this back into any of the two equations to find the length.

L = 4W

L = 4(16)

L = 64

So the width is 16, and the length is 64.

What is the product of -2x^3+x-5 and x^3-3x-4 ? (a) Show your work

saul85 [17]

Answer:

-3x3 - 2x - 4

Step-by-step explanation:

((((2•(x3))+x)-5x3)-3x)-4

(((2x3 + x) - 5x3) - 3x) - 4

Pulling out like terms :

4.1 Pull out like factors :

-3x3 - 2x - 4 = -1 • (3x3 + 2x + 4)

Polynomial Roots Calculator :

4.2 Find roots (zeroes) of : F(x) = 3x3 + 2x + 4

Polynomial Roots Calculator is a set of methods aimed at finding values of x for which F(x)=0

Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers x which can be expressed as the quotient of two integers

The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient

In this case, the Leading Coefficient is 3 and the Trailing Constant is 4.

The factor(s) are:

of the Leading Coefficient : 1,3

of the Trailing Constant : 1 ,2 ,4

Let us test ....

P Q P/Q F(P/Q) Divisor

-1 1 -1.00 -1.00

-1 3 -0.33 3.22

-2 1 -2.00 -24.00

-2 3 -0.67 1.78

-4 1 -4.00 -196.00

-4 3 -1.33 -5.78

1 1 1.00 9.00

1 3 0.33 4.78

2 1 2.00 32.00

2 3 0.67 6.22

4 1 4.00 204.00

4 3 1.33 13.78

Polynomial Roots Calculator found no rational roots

Final result :

-3x3 - 2x - 4
