Find the value of (x + 1) in this equation.<br><br> 13(6x − 5) − x = 13 − 2(x + 1)
Mandarinka [93]

Answer: The value of x is 155/79.

Step-by-step explanation:

13(6x -5 )-x= 13 -2(x +1)

78x - 65- x = 13 -2x -2

77x -65 = 11-2x  

79x -65 =11

79x =76

x = 76/79    76/ 79 + 1/1  = 155/79

If two points on line l above have coordinates (0, A) and (2, −3), and the slope of the line is A, then what is the value of A?
Vlada [557]

Answer:

A = -1

So, option (B) is the correct answer.

Step-by-step explanation:

The two points on line have coordinates: p (x₁, y₁) = (0, A) and q(x₂, y₂) = (2 , -3)

Slope of line = A

Slope of line = \frac{y_{2} - y_{1}}{x_{2} -x_{1}}

Now since the slope of line is A  and its has two coordinates (0, A) and (2 , -3), ∴

A = \frac{y_{2} - y_{1}}{x_{2} -x_{1}}

A = \frac{-3 - A}{2 - 0}

2A = -3 - A

2A + A = -3

3A = -3

A = -1

So, option (B) is the correct answer.
