Step-by-step explanation:
Given,
y = - 10x + 25
To find, the total number of solutions = ?
∴ y = - 10x + 25
⇒ y = - 2(x)(5) +
⇒ y =
There are infinite solution of y.
Thus, there are infinite solution of y.
Answer:
Tiffany is 34% closer to the school.
Step-by-step explanation:
Given the statement: Tiffany used to live 15 kilometers away from the school, but after she moved she now lives 9.9 kilometers away.
She lived away from the school = 15 km
as, she moved 9.9 km away.
Now, the distance closer to school from where she lived = 15 -9.9 = 5.1 km
To, find how much percent she is closer to school.
Percent states that a number or ratio expressed as a fraction of 100.
=
Simplify:
percent closer to school = 34%
Therefore, she is 34% closer to the school.
