Answer:
The y-axis.
Step-by-step explanation:
This is because it is mirroring across the y-axis, and the x-coordinate's sign is getting changed from positive to negative.
We can set up a system of equations to solve this.
120b + 90d = 270
60b + 110d = 265
To cancel out b, first make the b terms equal.
60b · 2 + 110d · 2 = 265 · 2
120b + 220d = 530
Now subtract the equations.
120b + 90d = 270
-120b + 220d = 530
---------------------------
-130d = -260
Solve for d.
-130d/-130 = -260/-130
d = 2
Now put the value of d in one of the equations.
60b + 110d = 265
60b + 110 · 2 = 265
60b + 220 = 265
60b + 220 - 220 = 265 - 220
60b = 45
60b/60 = 45/60
b = 0.75
Each candy bar sells for $0.75
Hope this helps! :)
Answer:
Uh I think 6
Step-by-step explanation:
The solutions to a function are the points where the graph of the function crosses the x-axis, but only if the solutions are real numbers. If the function has imaginary solutions, then you don't see those on the graph.
Answer:
Five pencils and two marches are worth greater than thirty paper clips.
Step-by-step explanation:
Let 'x' be paper clip.
Let 'y' be a match
and let 'z' be a pencil.
Now, let's write each statement as an equation:
Each paper clip can be traded for three matches:
x = 3y
Each pencil can be traded for six paper clips:
z = 6x
Now, five pencils equals 30 paper clips and two matches equals two thirds papel clips.
Therefore, we can say that Five pencils and two matches equals 30.66 matches. Therefore, five pencils and two marches are worth greater than thirty paper clips.
