It’s going to be 140, if you need to show work it’s 180-130=50 then 180-90=90 then 90+50=140

∠AED + ∠AEB = 180° (linear pairs)

∠AED + 90° = 180°

∠AED = 90°

Again,

∠DEC + ∠BEC = 180° (linear pairs)

∠DEC + 130° = 180°

∠DEC = 180° - 130°

∠DEC = 50°

Now,

∠AEC = ∠DEC + ∠AED = 90° + 50° = 140°

What is the y-intercept Of the function Represented by the table of values belowX -2 1 2 4 7 y 15 6 3 -3 -12

Kipish [7]

Given:

The table of values.

To find:

The y-intercept of the given function.

Solution:

The table of values represents a linear function because the rate of change is constant.

Consider any two points from the given table. Let the two points are (-2,15) and (1,6). Then the equation of the linear function is

$y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)$

$y-15=\dfrac{6-15}{1-(-2)}(x-(-2))$

$y-15=\dfrac{-9}{1+2}(x+2)$

$y-15=\dfrac{-9}{3}(x+2)$

$y-15=-3(x+2)$

Adding 15 on both sides, we get

$y=-3x-6+15$

$y=-3x+9$

Putting x=0, we get

$y=-3(0)+9$

$y=0+9$

$y=9$

The y-intercept is 9. Therefore, the correct option is C.
