Answer:

If the graph crosses the x-axis and appears almost linear at the intercept, it is a single zero. If the graph touches the x-axis and bounces off of the axis, it is a zero with even multiplicity. If the graph crosses the x-axis at a zero, it is a zero with odd multiplicity. The sum of the multiplicities is n.

2.) If ZA = (20 – 2m)º and ZD = (m – 130°, what is the value of m?

vivado [14]

Answer:

m = 50

Step-by-step explanation:

∠ D and ∠ A are vertically opposite angles and are congruent , then

m - 130 = 20 - 2m ( add 2m to both sides )

3m - 130 = 20 ( add 130 to both sides )

3m = 150 ( divide both sides by 3 )

m = 50

Multiply or divide as indicated. x^-8 • x^-2

gladu [14]

ANSWER

$\frac{1}{ {x}^{10} }$

EXPLANATION

The given exponentiial expression is

${x}^{ - 8} \bullet {x}^{ - 2}$

We simplify using the rule:

${a}^{m} \times {a}^{n} = {a}^{m + n}$

We apply this property to get:

${x}^{ - 8} \bullet {x}^{ - 2} = {x}^{ - 8 + - 2}$

We simplify to get;

${x}^{ - 8} \bullet {x}^{ - 2} = {x}^{ - 10}$

We rewrite as a positive index to get;

${x}^{ - 8} \bullet {x}^{ - 2} = \frac{1}{ {x}^{10} }$

A quadrilateral PQRS is translated to the left by 4 units to obtain another quadrilateral P᾿Q᾿R᾿S᾿

IrinaVladis [17]

Answer:

the length of PQ is equal to the length of P'Q'

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, translation and dilation.

Translation is the movement of a point either up, down, right or left. Translation is a type of rigid transformation. Rigid transformation is a transformation in which both the image and pre-image have the same shape and size. types of rigid transformation are rotation, reflection and translation.

Quadrilateral PQRS is translated to the left by 4 units to obtain another quadrilateral P᾿Q᾿R᾿S᾿. Since translation is a rigid transformation, the shape and size of PQRS is the same as that of P'Q'R'S. Hence the length of PQ is equal to the length of P'Q'.
