Sonbull [250]

Answer:

C

Step-by-step explanation:

\frac{ - 20 {x}^{2}  + 14x + 12}{5x - 6}  \\  \\  =   \frac{- (20 {x}^{2}   - 14x - 12)}{5x - 6}  \\  \\ =   \frac{ - (5x - 6)(4x + 2)}{5x - 6}  \\  \\  =  - (4x + 2 ) \\  =  - 4x - 2

Domain:

g(x) ≠ 0

5x - 6 = 0 \\ 5x = 6 \\  \\ x =  \frac{6}{5}

All real numbers ≠ 6/5

On the grid draw a scaled copy of quadrilateral ABCD with a scale factor 2/3
Tamiku [17]

Answer:

Attached diagram A'B'C'D'

Step-by-step explanation:

Given is a quadrilateral ABCD. It says to draw a dilated version with a scale factor 2/3.

We see that scale factor is less than 1 which means it shrinks the image to a smaller one.

To draw a scaled copy, we need to find the lengths of its sides.

To do so, we can draw the diagonals AC & BD, and they intersect at origin O(0,0) such that OA= -2, OB= 2, OC= 4, OD= -4.

Applying a scale factor of 2/3, we get OA' = -4/3, OB' = 4/3, OC' = 8/3, OD' = -8/3.

So we have attached a scaled copy A'B'C'D' of quadrilateral ABCD with a scale factor 2/3.
