Answer:

<h2>Reflection across the y-axis and 1 unit shift downside.</h2>

Step-by-step explanation:

Notice that shape A is in the second quadrant and shape B is in the first quadrant. That means there was a reflection across y-axis and then the figure was shifted one unit downside.

Therefore, the transformation was reflection across the y-axis and 1 unit shift downside. Which is a rigid transformation, because the shape and size didn't change.

An angle measures 19.4° more than the measure of its complementary angle. What is the measure of each angle?

8090 [49]

Answer:

37.8+52.2=90

Step-by-step explanation: x + (x + 14.4) = 90

2x + 14.4 = 90

2x = 75.6

x = 37.8 (one angle)

And (x + 14.4) = 52.2 (other angle).

When the two equations are graphed on a coordinate plane, they intersect at two points.

Law Incorporation [45]

Answer:

(0,4) and (-2,0)

Step-by-step explanation:

y=3x²+4x+4

y = -2x +4

3x²+4x+4 = - 2x +4

3x²+6x=0

3x(x+2)=0

x=0, x= -2

x=0, y=-2x+4= -2*0 + 4 =4, (0,4)

x= - 2, y = 2x + 4= 2*(-2) +4=0, (-2,0)

Can you please show work

fgiga [73]

Answer:

A) 3.44 ft²

Step-by-step explanation:

before cutouts, the area was 4 x 4 = 16 ft²

the circles have a diameter of 2 ft each, and a radius of 1 ft

each circle has an area pf (3.14)(1²) = 3.14 ft²

3.14 x 4 = 12.56 ft²

16 - 12.56 = 3.44 ft² left
