Answer:

A

Step-by-step explanation:

When graphed, the graph stretches out to the negative side of the x axis, causing the answer having to be x being less than 0. And the answer could also be all real numbers in some occasions, but the graph doesn't also stretch out to the positive side of the x axis. And domain contributes to x, so answer D is also cut off as an option.

Never mind, I mathed wrong T_T, it's C I guess

Problem 10 / (Second Session 2006)

hammer [34]

Answer:

Find other solutions in explanation

x = 250

y = 1750

Step-by-step explanation:

x = cost per copybook

y = cost per pen

2. Sum of the cost of 4 copy books and 3 pen is equal to 7750

3.)

2x+y=2750 - - (1)

4x + 3y = 7750 - - - (2)

From (1)

y = 2750 - 2x

Substitute y = 2750 - 2x into (2)

4x + 3(2750 - 2x) = 7750

4x + 8250 - 6x = 7750

-2x = - 500

x = 500/2

x = 250

y = 2750 - 2(500)

y = 2750 - 1000

y = 1750

Answer:

2x

Step-by-step explanation:

when the base is the same, we subtract when dividing, so

3-2=1, 2x^1=2x

What is the degree of polynomial?<br>With example!

Inessa [10]

Answer:

$\boxed{\mathfrak{Question ~}}$

What is the degree of polynomial?

$\large\boxed{\mathfrak{Answer}}$

The degree of a polynomial is the highest of the degrees of the polynomial's monomials with non-zero coefficients.

Example:

${6x}^{4} + {2x}^{3} + 3$

4x The Degree is 1 (a variable without an

exponent actually has an exponent of 1)

More Examples:

4x^ − x + 3 The Degree is 3 (largest exponent of x)

x^2 + 2x^5 − x The Degree is 5 (largest exponent of x)

z^2 − z + 3 The Degree is 2 (largest exponent of z)

A constant polynomials (P(x) = c) has no variables. Since there is no exponent to a variable, therefore the degree is 0.

3 is a polynomial of degree 0.

The distance between two points is 6_/6.One endpoint is (4,-1). It is known that the y-coordinate of the other endpoint is 9.

babunello [35]

The x-coordinate of the given endpoint will be " $x = 4 \pm 2\sqrt{29}$ ".

According to the question,

The end points are:

$(x_1,y_1) = (4,-1)$
$(x_2, y_2) = (x,9)$

Distance,

$6\sqrt{6}$

As we know,

The distance formula,

→ $Distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

By substituting the values, we get

→ $6\sqrt{6} = \sqrt{(x-4)^2+(9+1)^2}$

→ $216= (x-4)^2+100$

→ $(x-4)^2 = 116$

→ $x-4 = \pm \sqrt{116}$

→ $x-4=\pm 2\sqrt{29}$

→ $x = 4 \pm 2\sqrt{29}$

Thus the above answer is right.
