Expand 5 ( 2 x - 3 ) - 6 x :

5 ( 2x - 3 ) - 6 x

Expand 5 ( 2 x - 3 ) :

= 10 x - 15 - 6 x

= 10 x - 6 x - 15

= 4 x - 15

Answer B : 4 x - 15 ≤ 30

hope this helps!.

1.   ⁻¹/₂x - 5y = -10
  -2(⁻¹/₂x - 5y) = -2(-10)
  -2(⁻¹/₂x) - 2(-5y) = 20
  x + 10y = 20
x + 10(0) = 20
x + 0 = 20
x = 20
The answer is B.

2. y - y₁ = m(x - x₁)
  y - 1 = ⁻⁴/₅(x - 5)
  y - 1 = ⁻⁴/₅(x) - ⁴/₅(-5)
y - 1 = ⁻⁴/₅x + 4
+ 1 + 1
y = ⁻⁴/₅x + 5
-5(y) = -5(⁻⁴/₅x + 5)
-5y = -5(⁻⁴/₅x) - 5(5)
-5y = 4x - 25
-4x - 5y = 4x - 4x - 25
  -4x - 5y = -25
  -1(-4x - 5y) = -1(-25)
-1(-4x) - 1(-5y) = 25
  4x + 5y = 25
The answer is B.

3. 5(2x - 3) - 6x ≤ 30
5(2x) - 5(3) - 6x ≤ 30
10x - 15 - 6x ≤ 30
10x - 6x - 15 ≤ 30
4x - 15 ≤ 30
+ 15 + 15
4x ≤ 15
4 4
x ≤ 3³/₄
Solution Set: {x|x≤ 3³/₄}, (-∞, 3³/₄]
The answer is B.

4. $f(x) = \frac{x - 3}{2x - 5}$
2x - 5 ≠ 0
+ 5 + 5
2x ≠ 5
2 2
x ≠ 2¹/₂
(-∞. 2¹/₂) ∨ (2¹/₂, ∞)
The answer is D.

5. $\frac{5}{\sqrt{2}} = \frac{5}{\sqrt{2}} * \frac{\sqrt{2}}{\sqrt{2}} = \frac{5\sqrt{2}}{\sqrt{4}} = \frac{5\sqrt{2}}{2}$
The answer is A.
