Answer:
35.612
Step-by-step explanation:
rate of change for 2x+4y=10
here rate of change can be found by finding slope
the general form for slope is y=mx+b
isolating y on the left side:
2x+4y=10
4y=
-2x+10
from here slope is -1/2
Rate of change =-1/2
Answer:

Step-by-step explanation:
Hello! to solve this exercise we must apply algebra and the concept of the equality of the equations, remember what we do on the side of the equation we must repeat it on the other side in order not to alter the equality


to verify the solution we replace x in the original equation
