The vertices of ABC are A(-3,5), B(-2,3), and C(-5,3). If ABC is reflected across the y-axis to produce the image A'B'C', find t
Nat2105 [25]

Answer:

C' =(5,3)

Step-by-step explanation:

Given

A = (-3,5)

B = (-2,3)

C = (-5,3)

Reflection across y-axis

Required

Find C'

For reflection across y-axis, the rule is:

(x,y) \to (-x,y)

So, the image of C is:

(-5,3) \to (-(-5),3)

(-5,3) \to (5,3)

Hence:

C' =(5,3)

Please help and show your work ( no links or files) plz
mr_godi [17]

Answer:

Step-by-step explanation:

Use the formula for the area of a triangle,

Area of a triangle = \frac{1}{2}(\text{Base})(\text{Height})

7). Area of the triangle = \frac{1}{2}(20)(7.4)

                                       = 74 km²

8). Area of the triangle = \frac{1}{2}(4)(15.4)

                                     = 30.8 cm²

9). Area of the triangle = \frac{1}{2}(16)(7)

                                      = 56 m²

10). Area of the triangle = \frac{1}{2}(11)(7.7)

                                       = 42.35 km²
