Answer:
The answer is Congruent: (x,y)-(x+5,y), (x,y)-(x,-y),(x,y)-(-x,-y) Not Congruent: (x,y)-(5x,5y)-(x,y)-(0.5x,0.5y). Or the answer for congruent is answer choice 1, 4 and 5. Not Congruent is answer choice 2 and 3.

Answer:
Step-by-step explanation:
Question 1. 5b + 2 = 17
Step 1. Subtract 2 from both sides of the equation.
5b+2-2=17-2
Step 2. Then simplify.
5b=15
Step 3. Finally divide by 5.
5b/5=15/5
Answer: b=3
Question 3.
Step 1. Subtract 9 from both sides.
9+4b-9=17-9
Step 2. And simplify.
4b=8
Step 3. Finally divide by 4.
4b/4=8/4
Answer: b=2
Hope this helps! :)
Answer:
$32 for five large pizzas.
Step-by-step explanation
Well, 27 ÷ 4 = 6.75 per pizzas. 32 ÷ 5 = $6.4 per pizza. For five, you pay less.

The proportionality constant of the given graph is k = 16.
<h3>How to find the proportionality constant of a graph?</h3>
The proportionality constant of a graph is the ratio of the y-coordinates to the x-coordinates.
Thus, it is written as k = y1/x1 = x2/y2 = ... = yn/xn
<h3>Calculation:</h3>
The given graph has the coordinates as
x = 0; y = 0 i.e., (0, 0)
x = 0.5; y = 8 i.e., (0.5, 8)
x = 1; y = 16 i.e., (1, 16)
x = 1.5; y = 24 i.e., (1.5, 24)
and so on.
Then, the ratio of y - coordinate to the x - coordinate is
k = 8/0.5 = 16
or
k = 16/1 = 16
or
k = 24/1.5 = 16
and so on.
So, the proportionality constant for the given graph is k = 16.
