The question asks for the length of CD and HJ. To find those, we need to find a connection between them.

In the given statement, it says ABCD ≅ FGHJ. When we look at the equation, the corresponding letters are equal. For example, angle A is congruent to Angle F. Or BC ≅ GH.

So we know that CD and HJ are congruent.
Set them equal:
2x + 3 = 3x + 2
Subtract 2x from both sides:
3 = x + 2
Subtract 2 from both sides:
x = 3
If x is 3, plug it in:
3(3) + 2
Simplify:
9 + 2 = 11

So, HJ is 11. And because HJ ≅ CD, CD is 11 too.

Which inequality is represented by this graph? Also, if someone could tell me how this works that would be great :D
inysia [295]

Answer:

y > -1/6 x+1

Step-by-step explanation:

The graph line is dotted.  Dotted lines means greater than or less than.  ( <, >)

Solid lines means less than or equal to     or greater than or equal to   (≤,≥)


Since the graph is shaded above the line, that means y is greater than the line.  If it were shaded below the line,  y would be less than.

y > -1/6 x+1

Three bags of chips and sodas cost $12.50. Four bags of chips and two sodas cost $10.00. What is the cost of each item? ASAP pls
Helen [10]

Step-by-step explanation:

3c + 3s = 12.50

4c + 2s = 10.00

3S = 12.50-3c

s = 4.17 - c

4c + 2 (4.17-c) = 10.00

2c + 8.34 = 10.00

2c = 1.66

chips = 0.83

soda = 3.34
