ABC is reflected over the y-axis
uranmaximum [27]

Answer:

A'(-1, 5), B'(-2, 3), and C'(-5, 4)

Step-by-step explanation:

Given the coordinate (x, y), if reflected over the y-axis, the resulting coordinate will be (-x, y):

Given the coordinates of the triangle expressed as:

A(1. 5), B(2, 3), and C(5, 4)

When these coordinates are reflected over the y-axis, the results will be:

A'(-1, 5), B'(-2, 3), and C'(-5, 4)

<em>Note that the x coordinates were negated while the y-coordinates remains unchanged</em>

Graph the image of the given triangle under a dilation with a scale factor of 1/2 and center of dilation ​ (0, 0) ​ .
Irina-Kira [14]

Vertices of the given triangle are:  (0, 0) , (8, 0) and (-6, 0)

If we dilate the triangle with a scale factor of 1/2 , then the new vertices will be...

(0*\frac{1}{2}, 0*\frac{1}{2} )= (0,0)

(8*\frac{1}{2}, 0*\frac{1}{2} )= (4,0)

(0*\frac{1}{2}, -6*\frac{1}{2} )= (0,-3)

Now we will just plot those vertices for getting the dilated triangle.

timurjin [86]

x+7+x=165

2x+7=165

2x+7-7=165-7

2x=158

2x÷2=158÷2

x=79

79+7+79=165
