Answer:

y = - 8

Step-by-step explanation:

y = 3 is the equation of a horizontal line parallel to the x- axis.

The equation of a parallel line must therefore be a horizontal line with equation

y = c

where c is the value of the y- coordinates the line passes through.

Here the line passes through (- 2, - 8) with y- coordinate - 8, thus

y = - 8 ← equation of parallel line

What is the solution to this equation? 6(x-3)=3x+9

Vikki [24]

Answer:

X = 9

Step-by-step explanation:

6(x−3)=3x+9

(6)(x)+(6)(−3)=3x+9

6x+−18=3x+9

6x−18=3x+9

6x−18−3x=3x+9−3x

3x−18=9

3x−18+18=9+18

3x=27

3x /3 = 27 /3

What is the solution to the equation |x − 4| = 17?

andrey2020 [161]

$~~~~~~|x-4| = 17\\\\\implies x -4 = 17~~~~ \text{or}~~~~~ x -4 = -17\\\\\implies x = 17+4~~~~\text{or}~~~~~ x = -17+4\\\\\implies x = 21~~~~~~~~~\text{or}~~~~~x = -13$

How to show the work for x4-y4

Juli2301 [7.4K]

I think you can solve it by
=(x^2 - y^2) *( x^2 + y^2)
= (x -y)*(x+y)*(x^2 + y^2)

In triangle ABC, angle A is 75o and angle B is 20o. Select the triangle that is similar to triangle ABC.

Arturiano [62]

Answer:

A. $\triangle$ DEF where $\angle D = 75^{\circ}$ and $\angle E = 20^{\circ}$ .

Step-by-step explanation:

At first we must keep in mind that two triangles are similar when they have same angle configuration, that is, each pair of angles is congruent. If $\triangle$ ABC and $\triangle$ DEF, then $\angle A \equiv \angle D$ and $\angle B \equiv \angle E$ . Hence, $\angle D = 75^{\circ}$ and $\angle E = 20^{\circ}$ .

In a nutshell, correct answer is A.
