Answer:
Identity
Step-by-step explanation:
Let's find the rates at which Melinda and Marcus are saving money and compare them.
Based on the table, we can see that Melinda originally had $75. Then she got $135 in 5 weeks. So the rate of saving money is (135–75)/5 = $12 per week.
This rate is unchanged for the next weeks. As we can see, she got $195 in the next 5 weeks. So she saved $60 more those 5 weeks, or the rate is $60/5 = $12 per week again.
So Melinda saved $12 per week.
As for Marcus, the equation tells us that the rate of saving money is $14 which is the coefficient in front of x.
Hence, t<span>he rate at which Melinda is adding to her savings each week is 2$
less than the rate at which Marcus is adding to his savings each week.</span>
Answer:
g(5x)= 20
Step-by-step explanation:
g(x)=4 is basically saying that 1 x is equal to 4.
g(5x) wants to know what 5 times 1 x is equal to (5 times 4 (4 is equal to 1 x)
g(5x)= 5(x=4)
g(5x)= 20
