1- start with the original equation

x=2y+70

Let y =3x

x=2x 3x+70

simplify

x=6x+70

2-solve for x.

x=6x+70

Subtract 6x from both sides

x-6x=70

simplify x-6x to -5x

-5x=70

divide both sides by -5

x=- 70/5

simplify 70/5 to 14

x=-14

3- start with an original equation .

y=3x

Let x =-14

y=3x -14

simplify

y=-42

therefore

x=-14

y=-42

Write equations for the horizontal and vertical lines passing through the point (4, -5).
raketka [301]

Answer:

Horizontal line: y=-5

Vertical line: x = 4

Step-by-step explanation:

As we have to determine the equations for the horizontal and vertical lines passing through the point (4, -5).

  • To determine the equation for the horizontal line passing through the point (4, -5), we must observe that the horizontal line will always have the same y-value regardless of the x-value.

Therefore, the equation of the horizontal line passing through the point (4, -5) will be: y=-5

  • To determine the equation for the vertical line passing through the point (4, -5), we must observe that the vertical line will always have the same x-value regardless of the y-value.

Therefore, the equation of the vertical line passing through the point (4, -5) will be: x=4

Hence:

Horizontal line: y=-5

Vertical line: x = 4

we know, that the angle formed by an arc at the center of the circle is two times the angle formed by same arc on any point on the circumference,

So,

=》

angle \: 1 = 2 \times angle \: 2

hence, correct answer is B.
