Answer:
The second stove had a higher temperature when the stoves were turned off.
The first stove cooled down at a faster rate.
Step-by-step explanation:
first stove: T(t) = 180 - 2.55t can also be written as T(t) = -2.55t + 180
(180 is the y-intercept; -2.55 is the slope)
second stove = T(t) = mt + 200
(0,200) (40,130)
= = = -1.5
T(t) = -1.5t + 200
Answer:
45
Step-by-step explanation:
negative times negative equals positive
A number <em><u>cannot</u></em> be greater than and less than -1 at the same time. It can be greater than or equal to, but not strictly greater or lesser.
Good luck!
It is a trinomial because it has three terms and it is not a perfect square nor a difference of squares.
Given :
June's mother was 29 when June was 5 years old.
To Find :
How old will June be when she is one-quarter her mother's age.
Solution :
Let, age of June when she is one-quarter her mother's age is x and mother's age is y.
So, y = 4x ...1)
Also, we know that difference between two person's age is constant.
So, y - x = 29-5
y - x = 24 ...2)
Solving equation 1 and 2, we get :
y = 32
Therefore, June will be 8 years old when is one-quarter her mother's age.
