Answer:

You can write equivalent expressions by combining like terms. Like terms are terms that have the same variables raised to the same powers. For example, the list shows some pairs of like terms. the new coefficient is 9.

Write the eqWrite the equation of the line, in point-slope form. Identify the point (-2, -2) as (x1, y1). Use the box provided o

puteri [66]

Given that the line passes through two points

(-2,-2) and (x1,y1)

Equation in point slope form is

y-y1 = m(x-x1)

substitute for slope

Hence equation of the line = $\frac{y2-y1}{x2-x1} =[tex]y-y1 = \frac{-2-y1}{-2-x1}(x-x1)$

Since we donot know the value of x1or y1 the equation would contain x1, y1 also as answer.

Answer in point slope form is

$\frac{y2-y1}{x2-x1} =[tex]y-y1 = \frac{-2-y1}{-2-x1}(x-x1)$

Match the correct theorem or postulate with the correct statement.

Roman55 [17]

1. Unique line postulate

Statement: Through any two points, there is exactly one line.

2. Line intersection postulate

Statement: If two lines intersect, then their intersection is exactly one point.

3. Segment addition postulate

Statement: If A, B and C are collinear and B is between A and C, then AB + BC = AC

4. Angle Addition postulate

Statement: If R is in interior of $\angle PQS$ , then $m \angle PQR + m \angle RQS = m \angle PQS$ .

5. Linear pair theorem

Statement: If two angles form a linear pair, then the angles are supplementary.

6. Congruent Complements theorem

Statement: If two angles are complementary to the same angle, then the angles are congruent.

Find the value of cos P rounded to the nearest hundredth, if necessary.

Lemur [1.5K]

Answer:

$\cos P\approx 0.26$

Step-by-step explanation:

In any right triangle, the cosine of an angle is equal to its adjacent side divided by the hypotenuse, or longest side, of the triangle.

In the given triangle, the adjacent side to angle P is marked as $\sqrt{7}$ and the hypotenuse of the triangle is $10$ . Therefore, we have:

$\cos P=\frac{\sqrt{7}}{10},\\\cos P=0.2645751311,\\\cos P \approx \boxed{0.26}$

An isometry preserves all all the following except

iogann1982 [59]

The correct answer to this question is letter "C. distance." An isometry is a transformation that preserves distance. Isometry is a geometrical transformation that preserves geometrical properties such as distance. In mathematics, an isometry (or congruence, or congruent transformation) is a distance-preserving injective map between metric spaces.
