Answer: A) (-1, 3)

Step-by-step explanation:

When reflecting across the y-axis the y value of the point stays the same and the x values flips to it's opposite.

The point of A on ΔABC is (1, 3)

The x value is 1. The opposite value of 1 is -1 giving us the coordinates (-1, 3)

Answer:

CDJ= 34

Step-by-step explanation:

We know that ADJ = 90 degrees  

ADK = 180 degrees  and JDK equals 90 degrees so ADJ must equal 90 degrees

ADJ = ADC+CDJ

ADJ =4x+ 3x-8

Since ADJ = 90 degrees

90 = 4x+3x-8

Combine like terms

90 = 7x-8

Add 8 to each side

90+8 = 7x-8+8

98 = 7x

Divide each side by 7

98/7 = 7x/7

14 =x

We want to know CDJ

CDJ = 3x-8

CDJ = 3(14) -8

CDJ = 42-8

CDJ= 34
