74+x+85+33= 180 (bc the sum of the angles of a triangle is 180º)

192=180-x

192-180=-x

12=-x

-12=x

Which is the equation of the given line in slope-intercept form? (-1, 2) and (1, -4)
Natalka [10]
1. Find the slope using the slope formula.
\frac{2 - ( - 4)}{ - 1 - 1}  =  \frac{2 + 4}{ - 2}  =  -  \frac{6}{2}  =  -  \frac{3}{1}  =  - 3
2. Plug that slope and either point into an equation in slope-intercept form and solve for b.
2 =  - 3( - 1) + b \\ 2 = 3 + b \\  - 1 = b
3. Now write your answer as a slope-intercept form equation
y =  - 3x - 1

I NEED HELP PLEASE ASAP!!​
sleet_krkn [62]

Option C:

The value of x is 27.

Solution:

Given exterior angles are 56°, 2x°, 85°, 57° and 4x°.

<em>Sum of exterior angles of a polygon = 360°</em>

⇒ 56° + 2x° + 85° + 57° + 4x° = 360°

⇒ 198° + 6x° = 360°

Subtract 198° from both sides of the equation.

⇒ 6x° = 162°

Divide by 6 on both sides, we get

⇒ x° = 27°

⇒ x = 27

The value of x is 27.

Option C is the correct answer.

For the function f(x) = |2x-7| - 3 find f(2)
olasank [31]
Evaluate abs(2 x - 7) - 3 where x = 2:abs(2 x - 7) - 3 = abs(2 2 - 7) - 3
2×2 = 4:abs(4 - 7) - 3
4 - 7 = -3:abs(-3) - 3
Since -3<=0, then abs(-3) = 3:3 - 3
