Find the slope of a line parallel to a line containing points (3,-5) and(1,7)

schepotkina [342]

Answer:

Required slope = - 6

Step-by-step explanation:

Parallel lines have same slope.

(x₁ , y₁) = (3 , -5) & (x₂ , y₂) = (1, 7)

$Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$= \frac{7 - [-5]}{1-3}\\\\=\frac{7+5}{1-3}\\\\=\frac{12}{-2}\\\\= -6$

Slope of the a line parallel to a line = -6

Type a digit that makes this statement true.

Aneli [31]

Answer:

1, 3, 5, 7, or 9

Step-by-step explanation:

For 14, 213, 1__2 to be divisible by 4, the last two digits must be divisible by 4.

Using this knowledge, any odd single digit number would make the statement true.

14, 213, 112 ÷ 4 = 3, 553, 278

14, 213, 132 ÷ 4 = 3, 553, 283

14, 213, 152 ÷ 4 = 3, 553, 288

14, 213, 172 ÷ 4 = 3, 553, 293

14, 213, 192 ÷ 4 = 3, 553, 298

Hope this helped!

Show that (-27x-9) / (3x^2+4x+1) is a transformation of 1/x.

Dominik [7]

Since the quotient of -27x + 9 and 3x² + 4x + 1 is equal to -9x⁻¹, it is equal to -9/x, which is a trans for mation of 1/x.
