Answer:
no solution
Step-by-step explanation:
L1 = 3y=3/2x+6
L2 = 1/2y-1/4x=3
Divide L1 by 3: y = 0.5x + 2
Multiply L2 by 2: y - 0.5x = 6, now isolate y: y = 0.5x + 6
we can see that both lines have the same gradient but different y-intercepts, therefore they never cross
The lengths of P,Q, and R are 6 ft 9 in, 11 ft 3 in and 15 ft 9
Answer:
48
Step-by-step explanation:
2 = 2 line 1
2 + 4 = 6 line 2
2 + 4 + 6 = 12 line 3
The next line we would add 12 since we are adding the sum of the previous line
2 + 4 + 6 +12 = 24 line 4
The next line we would add 24 since we are adding the sum of the previous line
2 + 4 + 6 +12+24 = 48 line 5

Step-by-step explanation:
<u>First Degree Equations</u>
A first-degree equation can have one, none, or infinitely many solutions.
An equation like
2x + 3 = -x + 6
Has one solution: x=1
An equation like:
4x + 2 = 4x + 1
Has no solutions because when trying to solve for x we get:
2 = 1
This equality is false and no value of x can make it true
Finally, the equation:
3x + 2 = x + 2x + 2
Has infiniteyl many solutions, because when trying to solve it, we get:
2 = 2
Which is true regardless of the value of x
- The first given equation:
3x + 9 + 4x + x = ??
can be simplified as:
8x + 9 = ??
For this equation not having solutions, we should have 8x plus any number but 9 on the right side of the equation:
8x + 9 = 8x -3, or
8x + 9 = 8x + 4
- The second given equation:
3x + 9 + 4x + x = ??
can be simplified as:
8x + 9 = ??
If the equation has one solution, the only condition is that we should not have 8x on the right side. Thus any of those will do:
8x + 9 = 3x + 9
8x + 9 = -x + 5
8x + 9 = 0
3x + 9 + 4x + x = ??
can be simplified as:
8x + 9 = ??
For this equation to have infinitely many solutions, the right side must be exactly equal to the left side:
8x + 9 = 8x + 9
