Multiplying the number by 1,000
Hello,
Let's suppose f(x)=3x+7
f(a-1)=3(a-1)+7=3a-3+7=3x+4
Answer B with a sign "++++++++++++++++++++++++++++"
Answer: markers are a dollar each and pencils are twenty five cents each
Step-by-step explanation:
2x1 = 2
5x.25 = 1.25
2+1.25= 3.25
4x1 = 4
6x.25= 1.50
4+1.30 = 5.50
Hope this helps and if you need me to explain it better feel free to ask!
Answer:
if an equation has the same slope and y intercept the equations will have infinite many solutions. If both equations have the same slope but different y intercept the equations will have no solutions. if both equations are positive or negative and have different slopes and different y intercepts then they will most likely have one solution. (example: y=-2x+3 and y= -4x+4, both slopes are negative so there will be one solution, same goes for if both slopes are positive.
Hope this helps!
