Answer:
The images are;
A' (5,2) B' (2,1) and C' (1,3)
Step-by-step explanation:
Firstly, we want to reflect across the x-axis
When we reflect a point (x,y) over X-axis, we
get (x,-y)
SO;
A (2,5) becomes (2,-5)

B (1,2) becomes (1,-2)
C(3,1) becomes (3,-1)
Then we proceed to rotate 90 degrees
counterclockwise about the origin
Here we have;
(×,y) becomes (-y,x)
(2,-5) becomes (5,2)
(1,-2) becomes (2,1)
(3,-1) becomes (1,3)

Which statement best describes the effect of replacing the function f(x) = 2x + 2 with the function g(x) = 2x - 3?
FrozenT [24]
The correct answer is: <span>The graph shifts 5 units right

Explanation:
Below is the graph attached of both the equations:

Red line: 
Represents f(x) = </span><span>2x + 2.
Blue line: Represents g(x) = 2x - 3.

As you can see in the graph that g(x) is shifted 5 units right to f(x).

If you move towards right by 1 unit, you have to subtract 1 from f(x) until you reach g(x) like:
2x + 2 - 1 = 2x + 1 (1 unit)
</span>2x + 1 - 1 = 2x (1 unit)
2x - 1 = 2x - 1 (1 unit)
2x - 1 -1 = 2x - 2 (1 unit)
2x -2 - 1 = 2x -3 (1 unit)

Total 5 units.

Hence the correct answer is t<span>he graph shifts 5 units right.</span>

Answer:

\huge\boxed{\sf 46}

Step-by-step explanation:

<u>Formula for area of rectangle:</u>

= length × width

<u>Area of the smaller rectangle:</u>

length = 7

width = 6

= 7 × 6

= 42

<u>Area of the larger rectangle:</u>

length = 7 + 4 = 11

width = 6 + 2 = 8

= 11 × 8

= 88

<u>Area of the shaded region:</u>

= Area of the larger rectangle - Area of the smaller rectangle

= 88 - 42

= 46

\rule[225]{225}{2}

Hope this helped!
