Answer:

y = 0

Step-by-step explanation:

- 7 + 21y + 23 = 16

- 7 + 23 =( 23 - 7) = 16

16 + 21y = 16

21y = 0

y = 0 \div 21

\boxed{\green{y = 0}}

-3x + 5y = -9

4x + 8y = 12

x + 2y = 3

Times three,

3x + 6y = 9

Add to the first equation,

11y = 0

y = 0

-3x + 5(0) = -9

x = 3

Answer:F B G E A

Step-by-step explanation:

1. F( a rigid transformation only changes the position but the size and angles remain the same)

2. B(The angle of rotation symmetry is the smallest angle the figure can be rotated to coincide with itself.)

3. G(Congruent means that it is the same size and shape)

4. E(Translation moves the whole shape including the points so that the shape and sizes remain the same)

5. A(Though it's position may change, reflective symmetry ensures that no other parts of the shape can change no matter what.)

Solve 5h + 2(11 - h) = -5 (Find h. Explain each step please.)
pav-90 [236]

Answer:

h = -9

Step-by-step explanation:

Distribute the 2 to the parentheses:

5h + 2(11 - h) = -5

5h + 22 - 2h = -5

Add like terms:

3h + 22 = -5

3h = -27

h = -9
