Answer:
top down: ∞, 0, 1, 0, ∞
Step-by-step explanation:
The equation will have infinite solutions when the left side and right side simplify to the same expression. This is the case for the first and last expressions listed.
2(x -5) = 2(x -5) . . . . expressions are already identical
x +2(x -5) = 3(x -2) -4 ⇒ 3x -10 = 3x -10 . . . the same simplified expression
__
The equation will have no solutions when the x-coefficients are the same, but there are different added constants.
5(x +4) = 5(x -6) ⇒ x +4 = x -6 . . . not true for any x
4(x -2) = 4(x +2) ⇒ x -2 = x +2 . . . not true for any x
__
The equation will have one solution when coefficients of x are different.
5(x +4) = 3(x -6) ⇒ 2x = -38 ⇒ x = -19
Answer:
5x maybe dont take my word

The answer is 975
Step-by-step explanation:
Apply the sum rule: ∑an + bn = ∑an + ∑bn
Answer:
x = 5/3
Step-by-step explanation:
Solve for x:
7 x - 15 = -2 x
Add 2 x to both sides:
7 x + 2 x - 15 = 2 x - 2 x
2 x - 2 x = 0:
7 x + 2 x - 15 = 0
7 x + 2 x = 9 x:
9 x - 15 = 0
Add 15 to both sides:
9 x + (15 - 15) = 15
15 - 15 = 0:
9 x = 15
Divide both sides of 9 x = 15 by 9:
(9 x)/9 = 15/9
9/9 = 1:
x = 15/9
The gcd of 15 and 9 is 3, so 15/9 = (3×5)/(3×3) = 3/3×5/3 = 5/3:
Answer: x = 5/3
Answer:
It is very difficult to read the points off of the graph as it is a little blurry
but
They are NOT parallel
red= 5/8
blue = 3/7 i think
