Answer:

-9i -j

Step-by-step explanation:

DE has components E - D = (-1, 5) -(8, 6) = (-1-8, 5-6) = (-9, -1). These components are the multipliers for the orthogonal unit vectors (i, j).

In terms of the unit vectors i and j, DE is ...

DE = -9i -j

4. gr - 8 = 34x - 12<br> Which exponent property did you use to solve for x? (1 point)

gogolik [260]

Step by step:
GR-8 = 34x - 12
• move variable to left hand side
-34x + gr -8 = - 12
• change expression and move to right side
-34x = - 12 - gr - 8
• calculate sum
-34x = - 4 - gr
• divide both sides
X = 2/17 + 1/34gr
And there’s your answer :)
