What to write it here
Orlov [11]

Answer:

84 degrees

Step-by-step explanation:

Angle A = 83 degrees

Angle B = x degrees

Angle C = 135 degrees

Angle CDE = 122 degrees

We know that the four inner corners of a quadrilateral should add up to 360 degrees. Two supplementary angles will add up to 180 degrees. Adjacent angles on a straight line will always be supplementary. Knowing this, just solve for <ADC and add that amount to <A and <C. Then, subtract that sum from 360 degrees.

<ADC = 180-122 = 58

58+83+135 = 276

360-276 = 84 degrees

What method can be used to write the equation of a line in slope-intercept form given two points? plzzzz answer im being timed ​
Trava [24]

Answer:

slope intercept form is : y = mx + b

where m is the slope and b is the y-intercept.

The slope, m = (y' - y)/(x' - x)

Is found using the two pints.

The apostrophe is used to denote the other point, different from point (x,y).

once you have the slope, m for the equation y = mx + b ; use one of the points as (x,y) to solve for b.

I need help :) please if you know this I would appreciate it if you can help me
elena-14-01-66 [18.8K]

Step-by-step explanation:

a.

2(3x) - 5x = 4

6x - 5x = 4

x = 4

B. -5(x-4)+8x=29

-5x+20+8x=29

3x+20=29

3x=9

x=3

C. 2y=18+2(3-y)

2y=18+6-2y

2y=24-2y

4y=24

y=6

D. c = -b - 11

3c + 6 = 6b

3( -b - 11) +6 = 6b

-3b-33+6=6b

-3b-27=6b

-27=9b

3=b

I neeeed help realy bad
77julia77 [94]

Answer: -3x + 4, (2,-2)

Step-by-step explanation:

First, you want to get y alone on one side.

3x + y = 4

     -4    -4        subtract 4 to get it on the left side.

     -y     -y       subtract y to get it alone on the right side.

Your'e left with 3x - 4 = -y      divide the whole equation by -1 do get a pos y

You then have y = -3x + 4. That's the first part of your answer.

To get the second part plug in (-3x + 4) into the y of the first equation, this is the substitution part.

-2x + 5(-3x+4) =-14        distribute the 5...     -2x - 15x +20 = -14

add your like terms ( x and x)                       -17x + 20 = -14

Isolate your x by subtracting the 20, both sides  -20   -20

-17x = -34    divide both side by 17 you get x = 2 (---- this is your first coordinate in the pair in your answer. To get the y do the same but solve for y instead of x.
