The image in the link shows two similar figures with same y-coordinates, but different x-coordinates.

Further, the x-coordinates of the LHS figure is the product of -1 and the x-coordinates of the RHS figure, and vice-versa.

Hence, the two images are a reflection of each other.

Since, y - coordinates remain same, the figures show reflection across the y-axis

<u>ANSWER TO PART A</u>

The given triangle has vertices $J(-4,1), K(-4,-2),L(-3,-1)$

The mapping for rotation through $90\degree$ counterclockwise has the mapping

$(x,y)\rightarrow (-y,x)$

Therefore

$J(-4,1)\rightarrow J'(-1,-4)$

$K(-4,-2)\rightarrow K'(2,-4)$

$L(-3,-1)\rightarrow L'(1,-3)$

We plot all this point and connect them with straight lines.

ANSWER TO PART B

For a reflection across the y-axis we negate the x coordinates.

The mapping is

$(x,y)\rightarrow (-x,y)$

Therefore

$J(-4,1)\rightarrow J''(4,1)$

$K(-4,-2)\rightarrow K''(4,-2)$

$L(-3,-1)\rightarrow L''(3,-1)$

We plot all this point and connect them with straight lines.

Can someone help me solve y/7 =22

Ipatiy [6.2K]

Answer:

y=154

Step-by-step explanation:

y/7=22

We simplify the equation to the form, which is simple to understand

y/7=22

Simplifying:

+ 0.142857142857y=22

We move all terms containing y to the left and all other terms to the right.

+ 0.142857142857y=+22

We simplify left and right side of the equation.

+ 0.142857142857y=+22

We divide both sides of the equation by 0.142857142857 to get y.

y=154
