The answer is B = (-1, -5)

Because -1 to 4 is 5 which is the run from
rise/run
So we would apply 2 - 7
Which would be - 5

Answer:

$y = \frac{ - 3x + 6}{2} = \\ x = 4 \\ y = \frac{ - 3 \times 4 + 6}{2} = \frac{ - 12 + 6}{2} = \frac{ - 6}{2} = - 3$

Answer:

b. The supplements of congruent angles are congruent

Explanation:

Note that $\angle TKL$ is a supplement of $\angle 3$ and $\angle TLK$ is a supplement of $\angle 4$ .

Since $\angle 3 \cong \angle 4$ , $\angle TKL \cong \angle TLK$ because the supplement of the congruent angles are congruent.

4x-y=20 and -2x-2y=10

lara31 [8.8K]

You can use Substitution to solve this problem:

4x-y=20

-y=-4x+20

y=4x-20

Now you have two equations, and you use the first one to substitute into the second one.

y=4x-20 and -2x-2y=10

-2x-2(4x-20)=10

-2x-8x+40=10

-10x+40=10

-10x=-30

-x=-3

x=3

Now that we have figured out what x is, we can substitute x in to one of the equations to figure out y.

4x-y=20 x=3

4(3)-y=20

12-y=20

-y=8

y=-8

<em><u>So your answer would be x=3 and y=-8</u></em>
