Answer:</h3>
29. e = D/(3f²)
30. k=-4, x=41 . . . . matches the 2nd selection
<h3>
Step-by-step explanation:</h3>
29. Multiply by the inverse of the coefficient of e. That coefficient is 3f², so you divide by that quantity.
... D = e(3f²)
... D/(3f²) = e . . . . . matches the first choice
___
30. You want to solve for k and use it with a different y-value.
... y = kx
... -96 = k·24
... -96/24 = k = -4
For y = -164, you have
... -164 = -4·x
... -164/-4 = x = 41
The coefficient of variation is -4, x is 41.
Answer:
X'(-3,-5)
Y'(-3,-2)
Z'(-7,-2)
Step-by-step explanation:
Write the ordered pairs as a vertex matrix.
To rotate the ∆XYZ 90 degrees counterclockwise about the origin, multiply the vertex matrix by the rotation matrix and then you are done.
