Mathematics
1 answer:
antiseptic1488 [7]4 years ago
7 0

Answer:

z=-4

Step-by-step explanation:

Simplify 10 + 2z + 2z to 10 + 4z

Add 10 to both sides

Simplify 10 + 4z + 10 to 4z + 20

Subtract 4z from both sides

Simplify -z - 4z − z− 4z to -5z − 5z.

Divide both sides by -5 − 5

Simplify 20 / 5 to 4

Answer:

Step-by-step explanation:

The slope of the line in question is the same as the slope of the line parallel to it. Using y = mx + b, where m is the slope, we find the slope of our line is -3.

Using the pt-slope form, y - y1 = m( x - x1), we get y - (-1) = -3( x - 2) or y + 1 = -3x + 6. Which leads us to y = -3x + 5. QED

Now, to answer the questions, the following calculations must be done:

  • C) 100 - (2/9x9) = X
