X +5+11x=12x+Y It says find the value of y that makes each equation true for all values of

Answers

Answer 1

Answer: x + 5 + 11x = 12x + y

Simplify: 12x + 5 = 12x + y (We are adding x and 11x on the left side)

Subtract 12x from each side makes each zero.

5 = y

So we can plug in and test. I'm picking two random numbers to plug in for x. 10, and 82

x = 10, y = 5
10 + 5 + 11(10) = 12(10) + 5
125 = 125

x = 82, y = 5
82 + 5 + 11(82) = 12(82) + 5
989 = 989

So we verified y = 5

Answers

X-axis = A (-7,-3) B (-7,-10) C (-1,-3) first they changed to the x-axis which is this. Just so you know on the x-axis the x-axis stay and the y-axis changed which is this.
When they reflect again on the y-axis the verter of A' is
A' (7, 3) = answer
On the y-axis the y- axis doesnt change but the x-axis changed.

A(-3, -7) B(2,-1) C(-2,0) D(-5,6)

Step-by-step explanation:

A(3,7) B(-2,1) C(2,0) D(5,-6)

180 rotation around origin = (-x,-y)

A(3,7) - A(-3,-7)

B(-2,1) - B(2,-1)

C(2,0) - C(-2,0)

D(5,-6) - D (-5,6)

Answer:

A(-3, -7) B(2,-1) C(-2,0) D(-5,6)

Step-by-step explanation:

A(3,7) B(-2,1) C(2,0) D(5,-6)

180 rotation around the origin would equal (-x,-y)

A(3,7) - A(-3,-7)

B(-2,1) - B(2,-1)

C(2,0) - C(-2,0)

D(5,-6) - D (-5,6)
