Answer:
CDE
Step-by-step explanation:
A) Only h(x) has a y intercept which is at x=0. At this point the y intercept is 0.
B) Only f(x) have a x intercept at f(x) = 0. The graph of f(x) touches the x axis at f(x) = 0.
C) h(x) has the lowest minimum, its minimum is at -28 while f(x) have a minimum at -14 and g(x) have a minimum at 1/49
D) The range of h(x) has more values than the other ranges ranging from -28 to -28.
E) g(x) has the highest maximum, its maximum is at 49 while f(x) have a maximum at 14 and h(x) have a maximum at 0

Answer:
True
Step-by-step explanation:
95 – 2x < 7 (15x – 17)
Answer:
x = 2
Step-by-step explanation:
From the question we are given the algebraic sign with the Inequality sign
95 - 2x < 7 (15x - 17)
In order to find all the possible values of x that makes the algebraic expression true ,
We solve for this by convert the less than(<) sign to =
A true statement or algebraic expression is when both values on the left hand side and right hand side of and algebraic expression is the same of equal to each other.
Therefore:
95 - 2x = 7 (15x - 17)
95 - 2x = 105x - 119
Collect like terms
95 + 119 = 105x + 2x
214 = 107x
x = 214/107
x = 2
In other to confirm if x = 2 makes the expression true
95 - 2x = 7 (15x - 17)
95 - 2x = 105x - 119
95 - 2 × 2 = 105 × 2 - 119
95 - 4 = 210 - 119
91 = 91
Therefore, the possible values for x that make the statement true is x = 2

The situation is best modeled by a linear function, considering the steady and constant rate of temperature decrease. Although this model does not account for other factors, it lays out a fundamental understanding of the time-temperature relationship in the given scenario.
The situation where the temperature of a coffee decreases by 5 F every 20 minutes is best modeled by a linear function. This is because the rate of decrease is steady and constant, meaning it fits the structure of a linear function: y = mx + b, where m is the slope (rate of decrease) and b is the y-intercept (initial temperature). In this case, the slope would be -5/20, as the coffee temperature decreases by 5 F every 20 minutes.
This concept is closely related to Newton's Law of Cooling in Physics, which postulates that the rate of loss of heat from an object is proportional to the difference in temperature between the object and its surroundings, provided the temperature difference is small. However, in this case, since we are dealing with a constant rate of cooling, the linear model is more appropriate.
While this model does not account for factors such as the volume of the coffee, heat transfer to the surroundings or the specific heat capacity of the coffee, it provides a basic understanding of the relationship between time and temperature in this scenario.
