Answer:

A.  y = 4x + 5 and y = 4x – 5

Step-by-step explanation:

If the system of equations have the same slope and different y-intercept, then it will have no solution.

From the given options, let's find the slope and y-intercept.

A. y = 4x  + 5 and y = 4x - 5

Slope = 4 and y-intercepts are 5 and -5

Here we have the same slope and different y-intercepts. So, this is systems of equations have no solution.

B. y = 4x + 5 and 2y = 8x + 10 => y = 4x + 5

Both are the same equations.

This system  has an infinite number of solutions.

The answer is A)  y = 4x + 5 and y = 4x – 5

A circular mirror is surrounded by a square metal frame. The radius of the mirror is 5x. The side length of the metal frame is 1
Aleks04 [339]

Answer:

-25x^{2} (\pi -9)

Step-by-step explanation:

The area of the metal frame is equal to the area of the square minus the area of the circle.

The area of the square is the side length squared:

(15x)^{2}

=225x^{2}

The area of the circle is \pi r^{2}, with r being the radius:

\pi (5x)^{2}

=\pi *25x^{2}

=25\pi x^{2}

Now find the area of the metal frame:

225x^{2} -25\pi x^{2}

25x^{2} (9-\pi )   Factor out the GCF, 25x^{2}

-25x^{2} (\pi -9)   Factor out a -1

PLEASE HELP WILL MARK BRAINLIEST..Write a polynomial function of least degree with rational coefficients so that P(x) = 0 has th
Svetlanka [38]

A polynomial function of least degree with rational coefficients so that P(x) = 0 has the given roots is P(x)=x²-5x-14

<h3>What is a polynomial function?</h3>

A function is said to as polynomial when a variable in an equation, such as a quadratic equation or cubic equation, etc., has only positive integer exponents or non-negative integer powers. One polynomial with an exponent of 1 is 2x+5, for instance. One that has more than two algebraic terms is referred to as a polynomial expression. Polynomial is a monomial or binomial that is repeatedly added, as the name suggests.

A mathematical expression containing one or more algebraic terms, where each algebraic term is made up of a constant multiplied by one or more variables raised to a nonnegative integral power.

x= -2, x=7

Given,

P(x) = 0

This polynomial function has the roots,

x= -2, x=7

So,

(x+2)(x-7)

We have to multiply both of them we get,

P(x)=(x+2)(x-7)

0=x²-5x-14

x²-5x-14=0

Therefore, P(x)=x²-5x-14 is the polynomial function.
