1. If triangle XYZ is reflected across the dr-axis to form triangle X'Y'Z', what is the coordinate of Y'?. (-3,2) (x, y) -> (-x,y). G (4,6) 9(3,2)-> (-3,2). H 2, -3). I (3,-2) … 3. -2. -. 1. 2. 3. 4. 5. تر. تا. نیا. If A + A, B →B', and C → C', A'B'C' is. What are the most likely coordinates of R' if R'S is … c translation of triangle ABC across the line.
Step-by-step explanation:
Using the distance formula, there is a Y difference of 6 and a X difference of 7. Create a triangle with those side lengths and solve for the hypotenuse. Sqrt85 is the exact answer. 9.2195 is the rounded.
For get the solution of this task, we must make the system of equations.First it: "The quotient between the sum of two numbers and one of them is equal to 3" Let's take two values: a and b.(a+b)/b=3 --- it's will be first equation in our system.
and "The inverse of double the sum of them and equal to 1/6"1/2(a+b)=1/6 it's will be second equation in our system.
Attention at parenthesis.
System(a+b)/b=31/2(a+b)=1/6
by the first equation:(a+b)/b=3a+b=3ba=2b --- we will use this equation for second equation in system
1/2(2b+b)=1/61/3b)=1/63b=6b=2 and a=2b, that's mean a=1.The answer is pair (1;2)
