The 4 arrows above the number line represents the distance between 2 and -2 which is 4!
Answer:
D
Step-by-step explanation:
Since BD and AE are parallel lines, then
∠BDC = ∠AED ( corresponding angles ), thus
4x - 5 = 97 - 2x ( add 2x to both sides )
6x - 5 = 97 ( add 5 to both sides )
6x = 102 ( divide both sides by 6 )
x = 17, hence
∠AED = 97 - 2x = 97 - (2 × 17) = 97 - 34 = 63°
∠BDE and ∠AED are same side interior angles and are supplementary, thus
10y - 3 + 63 = 180
10y + 60 = 180 ( subtract 60 from both sides )
10y = 120 ( divide both sides by 10 )
y = 12 → D
Answer:
The answer is sometimes.
If the two lines have the same slope, then there will be 0 solutions, and if the two lines are the same, then there will be infinite solutions.
Hope this helps!
Answer:
x = 
, y = 
Step-by-step explanation:
Express as 2 equations, that is
x + y = 1 → (1)
- x + 9y = 1 → (2)
Add the 2 equations term by term to eliminate x, that is
10y = 2 ( divide both sides by 10 )
y = 
=
Substitute this value into (1) and solve for x
x + = 1 ( subtract from both sides )
y = 
- =
