Answer:

Perpendicular

Step-by-step explanation:

The slope of the first equation is 0.3 = 3/10

You need the opposite sign of the reciprocal for perpendicular

10/3 is reciprocal, 3 1/3 is equivalent, - 3 1/3 is perpendicular

Answer:

$\boxed{D. 3 {x}^{2} - x - 6}$

Given:

$f(x) = 3{x}^{2} - 4 \\ \\ g(x) = x + 2$

To Find:

$(f - g)(x) = f(x) - g(x)$

Step-by-step explanation:

$= > f(x) - g(x) = (3{x}^{2} - 4) - (x + 2) \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 3{x}^{2} - 4 -(x) - (2)\\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: =3{x}^{2} - 4 - x - 2\\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: =3 {x}^{2} - x - 6$

Need help,please and thank you

If the two angles form a linear pair, the sum of the angles is 180 degrees.

If the small angle is one-third of the other, then the total is 1+1/3=4/3 of the larger angle.

By proportion,

L+L/3=4L/3=180

L=180*3/4=135 degrees

Smaller angle = L/3=45 degrees

Check: L+L/3=135+45=180 degrees, ok

Solve the equation. check your answer.<br>-14 = -4(9x - 1)

iragen [17]

Answer:

x = 0.5

Step-by-step explanation:

First, distribute -4 to the parentheses:

-14 = -4(9x - 1)

-14 = -36x + 4

Subtract 4 from both sides:

-18 = -36x

Divide each side by -36

0.5 = x

x = 0.5
