Which product is modeled by the number line below?

Gnoma [55]

Answer:

(B)(negative 2) (4)

Step-by-step explanation:

The arrow on the number line ended at negative 8 (-8).

Given the options:

(A) (negative 3) (4) =(-3)(4)=-12

(B)(negative 2) (4) =(-2)(4)=-8

(D)(3)(4)=12

The expected product is -8 since that is where the arrow ended. Therefore, the product that is modeled by the number line is that which gives a result of -8. The correct option is B.

(B)(negative 2) (4) =(-2)(4)=-8

X/x-2 + x-1/x+1= -1<br> Can someone walk me through the steps of this problem? Much appreciated. :)

Answer:

x = 0 or x = 1

Step-by-step explanation:

Given equation:

$\dfrac{x}{x-2}+\dfrac{x-1}{x+1}=-1$

Multiply the two denominators to get the same denominator:

Multiply the numerator of the first fraction by the denominator of the second fraction to get the new numerator of the first fraction.

Multiply the numerator of the second fraction by the denominator of the first fraction to get the new numerator of the second fraction.

$\implies \dfrac{x(x+1)}{(x-2)(x+1)}+\dfrac{(x-2)(x-1)}{(x-2)(x+1)}=-1$

Add the numerators and keep the denominator so that there is now one fraction:

$\implies \dfrac{x(x+1)+(x-2)(x-1)}{(x-2)(x+1)}=-1$

Simplify the numerator by expanding the brackets:

$\implies \dfrac{x^2+x+x^2-3x+2}{(x-2)(x+1)}=-1$

$\implies \dfrac{2x^2-2x+2}{(x-2)(x+1)}=-1$

Simplify the denominator by expanding the brackets:

$\implies \dfrac{2x^2-2x+2}{x^2-x-2}=-1$

Multiply both sides by the denominator of the left side:

$\implies 2x^2-2x+2=-1(x^2-x-2)$

Simplify and move everything to the left side:

$\implies 2x^2-2x+2=-x^2+x+2$

$\implies 3x^2-3x=0$

Factor:

$\implies 3x(x-1)=0$

Therefore:

$\implies 3x=0 \implies x=0$

$\implies x-1=0 \implies x=1$

Therefore, x = 0 or x = 1

An exterior angle of an isosceles triangle has measure 150°. Find two possible sets of measures for the angles of the triangle.

nasty-shy [4]

<span>_Award brainliest if helped!
If the exterior angle of the bases is 150°, then the measure of the angle of each base is
30° and the measure of the vertex is 120°. If the exterior angle of the vertex is 150°, then the measure of the angle of each base is
75° and the measure of the vertex is 30°.</span>
