The lines y=3x-1 and y=ax+2 are perpendicular if a=___
mezya [45]

Answer:

a = \frac{-1}{3}.

Step-by-step explanation:

The equation of line in the form .

y = mx + c

Where m is the slope and c is the y- intercept .

As given

The lines y=3x-1 and y=ax+2 are perpendicular .

Here 3 is slope for equation of line  y=3x-1 and a is slope for equation of line

y=ax+2 .

Now by using properties of the perpendicular lines property .

When two lines are perpendicular than slope of one line is negative reciprocal of the other line .

Thus

a = \frac{-1}{3}

Therefore a = \frac{-1}{3}.

Solve using inequalities <br>6&lt;k/9+7​
valentinak56 [21]

Answer:

Let's solve your problem step-by-step:

6 < k/9 +7

Step 1: Simplify both sides of the inequality:

6<1/9 k+7

Step 2: Flip the equation:

1/9 k+7 > 6

Step 3: Subtract 7 from both sides:

1/9 k+7 -7 > 6-7

1/9 k > - 1

Step 4: Multiply both sides by 9:

9 * (1/9) > (9) * (-1)

Answer: <u>k > − 9</u>

Step-by-step explanation:

Please mark me Brainliest!

Hope this helps! Good luck! :)
