(0, 0)
The origin is where the x-axis and the y-axis intersect
Answer:
3) x = 15; 95 and 85 4) x = 12; 98 for both angles
Step-by-step explanation:
2x + 65 + 3x + 40 = 180 Set the equations equal to 180
5x + 105 = 180 Combine like terms
- 105 - 105 Subtract 105 from both sides
5x = 75 Divide both sides by 5
x = 15
Plug 15 into both equations
2(15) + 65 = 95
3(15) + 40 = 85
4) 5x + 38 = 9x - 10 Set the equations equal to each other
- 5x - 5x Subtract 5x from both sides
38 = 4x - 10
+ 10 + 10 Add 10 to both sides
48 = 4x Divide both sides by 4
12 = x
Plug 12 into both equations
5(12) + 38 = 98
9(12) - 10 = 98
Answer:
-8-8-8
Step-by-step explanation:
Answer:
x=-16
Step-by-step explanation:
The given equation is:
x = 8a
which was written to find the value of x.
We have to find the value of x when the value of a is inserted as -2
So, putting the value
x = 8(-2)
x= -16
So the value of x when a = -2 is -16 ..
