Answer:
No solutions: 7−5+3x−1= 3x + 7
One solution: 7−5+3x−1= 2x + 4
Infinitely Many Solutions 7−5+3x−1= 3x + 1
Step-by-step explanation:
No solutions means it results in no x and a false statement like 3 = 0.
One solution means it results in x = a number.
Infinite solutions means its results in no x and in a true statement like 3=3.
- So to get No solutions: 7−5+3x−1= 3x + 7
This will eliminate the x and result in 1 = 7 which is false.
- One solution: 7−5+3x−1= 2x + 4
This will result in x= 3
- Infinitely Many Solutions 7−5+3x−1= 3x + 1
This will eliminate the x and result in 1 = 1 which is true.
First, find the price per cake
30/10 = 3
now just multiply!
3(25) = 75
the answer is $75
Answer:
I will assume the second equation is y=2x^3. If it is y=2x+3 or y=2x-3, the lines will never intersect: they have the same slope (2):
Step-by-step explanation:
2x – y = 7 can be rewritten as: y = 2x -7. It has a slope of 2. The second equation, y = 2x 3, isn't clearly written. If the 3 has a plus or minus sign, then the lines will never intersect: they have the same slope, 2.
I'll assume the second equation is y=2x^3.

Answer:
m - 3000
b - 2000
please correct me if i am wrong.
Step-by-step explanation:
You need to find the slope first. (-9,-4). (3,4)
-4-4= -8
-9-3 =-12. Slope is -8/-12 or 8/12 or 2/3
Perpendicular is the negative reciprocal. Or flip over the 2/3 and make it negative.
The answer is - 3/2
