Y = 3x + 4
y = 3x + 7
3x + 4 = 3x + 7
3x - 3x = 7 - 4
0 = 3.....incorrect....this system has no solutions because ur lines are parallel and they never cross.
or look at it this way..
y = 3x + 4
y = 3x + 7
both have slopes of 3...but the y intercepts are different......when this happens, it means the lines are parallel with no solution
1 A. 5
1 B. 12.9
2. For this one, u can write any number less than 4.7, which could be 3, 2, -100, 1.21, etc.
3. For this one, u can write any number greater than (positive!) 2.6, such as 10, 30, 3.1415, etc.
hope this helps!
Use the fact that 1 axe head = 3.20 trade value.
Let N denote number of axe heads needed to trade for a trade gun.
3.20×N=120.00
》 N=120/3.2 which will give number of axe heads needed. Round to the nearest ones place if you must.
Answer:
I think ( b) is non proportional linear
