What’s the value of DCB?<br> Pls help
amm1812

Answer:

78

Step-by-step explanation:

angle ACD + angle DCB = 180   (Angles on straight line)

4x + 2 + 3x + 3 = 180

7x + 5 = 180

7x = 180-5

7x = 175

x = 175 / 7

x = 25

angle DCB = 3x +3 = 3*25 + 3 = 75 +3 = 78

Look at the picture and answer question <br> Quick and simple respond pls
gogolik [260]

Answer:

It is not a good model because neither point lies on the line.

Step-by-step explanation:

We can test each point on the equation of the line.

7x - 10y = 3

Point: (8, 5)

7(8) - 10(5) = 56 - 50 = 6

The left side equals 6, not 3, so point (8, 5) is not on that line.

Point: (-12, -9)

7(-12) - 10(-9) = -84 + 90 = 6

The left side equals 6 again, but the right side is 3, not 6.

Answer: It is not a good model because neither point lies on the line.

Romashka-Z-Leto [24]

Answer:

I believe the answer is A

He is correct. If the second equation is multiplied by 2 and added to the first equation, the result is 0=3 , which means the system has no solution.
