Answer:

y= 2x -3

Step-by-step explanation:

The first thing you should know is that the slope of a perpendicular line is the opposite reciprocal. So, this is your current equation: y= 2x + b. Next, substitute your point into the equation to get the y-intercept. It should look like this: 9=2(6) + b. 6 times 2 equals 12. Now, this is what it should look like: 9=12 + b. Subtract 12 from both sides to get -3 = b. Go back to your original equation and plug in -3 to b. This is your final equation: y= 2x -3. Hope this helped!

PLEASE HELP ASAP!!! Y= [?] degrees

Elis [28]

Answer:

y = 25 degrees

Step-by-step explanation:

We start with 115° and x -

115° + x = 180°

x = 180° - 115°

x = 65°

The sum of all of the angles of a triangle will always be 180 degrees -

x + y + 90° = 180°

We substitute x with 65° -

65° + y + 90° = 180°

y = 180° - 65° - 90°

y = 90° - 65°

y = 25°

Plz help me I need because it’s one of my last assignments for school

Brums [2.3K]

Step-by-step explanation:

straight line = 180 degree

example

1) 2w - 24 + 2w - 40 = 180

4w = 180 + 24 + 40

4w = 244

w = 244/4

.......

2) 13n - 11 +(-9 + 12n)

13n - 11 -9 + 12n = 180

25n -20 = 180

25n = 180 + 20

25n = 200

n = 200/25

Simplify. Rewrite the expression in the form 4^n (4^6)(4^-8) =

stiks02 [169]

Answer:

4^-2

Step-by-step explanation:

The rules of exponents tell you ...

(a^b)(a^c) = a^(b+c)

This means ...

(4^6)(4^-8) = 4^(6-8) = 4^-2
