Answer:

y=-8.5

Step-by-step explanation:

You need to start by combining like terms.

So you would add -0.3y to both sides. Next you will subtract 21.3 from both sides. You should now have 5.4y=-45.9. At this point you will divide both sides by 5.4 giving you your answer of -8.5

5.1y + 21.3 = -o.3y - 24.6

+o.3y +0.3y

5.4y + 21.3 = -24.6

-21.3 -21.3

5.4y = -45.9

÷5.4 ÷5.4

y = -8.5

Answer:

-1

Step-by-step explanation:

We can use the slope formula when given two points

m= ( y2-y1)/(x2-x1)

   = ( 3-7)/(2 - -2)

   = (3-7)/( 2+2)

   = -4/4

Cerrena [4.2K]
<h3>Answers: </h3>

Angle 1 and 3:  Vertical Angles

Angle 4 and 8: Corresponding Angles

Angles 4 and 6: Alternate Interior Angles

Angles 3 and 5: Alternate Interior Angles

Angles 7 and 8: Linear Pair

Angles 1 and 7: Alternate Exterior Angles

=================================================

Explanation:

Vertical angles are formed when you cross two lines to form an X shape. The vertical angles are opposite one another in this configuration.

Corresponding angles are ones that show up in the same corner of each four-corner crossing. In the case of angles 4 and 8, both are in the southwest corner of each four-corner crossing.

Alternate interior angles are angles in between parallel lines and on opposite sides of a transversal. Alternate exterior angles are similar, but they are outside the parallel lines.

A linear pair of angles are adjacent and supplementary (meaning they add to 180).

3.5% = 0.035

122,591 x 0.035 = <em>$4,290.69</em>
