Six less than five times a number is at least 29.
1)Sin(29)=x/(30cm)
x=Sin(29)30cm
so be A is correct.
2) Cos A= a/b is correct because it is not true according to triangle.

Answer:
a1 = 8
a2 =10
a3 = 13
a4 = 17
Step-by-step explanation:
The first term is a1 = 8
The second term is a2 = a1 + n
= 8+2
= 10
The third term is a3 = a2 + n
= 10+3
= 13
The fourth term is a4 = a3 + n
= 13+4
= 17

Step-by-step explanation:
<u>Step 1: Define Systems</u>
-4x + 16 = y
2x - 32 = 2y
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: 2x - 32 = 2(-4x + 16)
- Distribute 2: 2x - 32 = -8x + 32
- [Addition Property of Equality] Add 8x on both sides: 10x - 32 = 32
- [Addition Property of Equality] Add 32 on both sides: 10x = 64
- [Division Property of Equality] Divide 10 on both sides: x = 32/5
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define original equation: -4x + 16 = y
- Substitute in <em>x</em>: -4(32/5) + 16 = y
- Multiply: -128/5 + 16 = y
- Add: -48/5 = y
- Rewrite/Rearrange: y = -48/5
