Hello!

So, the slope is 2, which means "up 2 over 1" because of rise over run and 2 is 2/1.  

You have to find the graph that as a line passing through (-2, -3), so the answer is going to be Graph D. 

Hope this helps :))

Use completing the square to solve the equation x^2 0 10x = 08.
wariber [46]
Ok so assuming the 0 means minus from typing problems

x^2-10x=-8

to completet  the square
make sure the term in front of x^2 is 1
that is correct
then take 1/2 of the term in front of the x term and square it
-10/2=-5, (-5)^2=25
add that to both sides
x^2-10x+25=17


answer is the first equation

Help Me5k = 6k + 4 - 6
vagabundo [1.1K]

Answer:

k = 2

Step-by-step explanation:

5k = 6k + 4 - 6

We can simplify this by solving 4 - 6 (replacing it with -2 !)

5k = 6k - 2

Now we can subtract 5k from both sides.

0 = k - 2

Finally, we can add 2 to both sides. This gets rid of the negative 2 on the right.

2 = k

Just reversing it...

k = 2

Answer: k = 2
