PLEASE help by explaining step by

44+x=180°

or x=180°- 44

:.x=136

in which clasd do you read

112

Step-by-step explanation:

1. A triangle is 180 degrees

2. Since the first angle is 44 that leaves you with 2 more angles

3. The half circles symbolize that they're the same

4. So the math starts now...

5. 180 (Triangle) - 44 (Angle 1) = 136

6. Since they are both the same (136 divided by 2 = 68)

7. But it doesn't end there... find x.

8. A line is also 180 degrees so...

9. Subtract 180-68= 112

10. x=112

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
