Answer:
-6x-12
Step-by-step explanation:
2(-3x-6)
Multiply: 2(-3x)+2(-6)
so answer is -6x-12
Solution:
we have been asked to find a function for the given sitatution
The given situation is
A movie store sells DVDs for $11 each. what is the cost C of n DVDs.
Cost of 1 DVD is $11, then the cost of 2 DVDS will be 2x11=$22.
Cost of 1 DVD is $11, then the cost of 3 DVDS will be 3x11=$33.
......................................................................................................................
.......................................................................................................................
Cost of 1 DVD is $11, then the cost of n DVDS will be nx11=$11n.
Since the price is increasing exactly by $11 for each additional DVDS so the Graph will be discrete.
Hence the correct option is C=11n, Discrete.
Answer:
A)
Step-by-step explanation:
Answer:
a) 35, b) 25, c) 60
Step-by-step explanation:
The number of girls is 10 more than the number of boys, so it's a good thing to choose a variable to represent the number of boys.
Number of boys: b
Number of girls: b + 10
Ratio of girls:boys is 7:5, so
"Cross multiply" to get
There are 25 boys. There are 10 more girls, so the number of girls is 35, and the total number of students is 60.
That's a packed classroom!
The graphed function, F(x), has a value greater than 0 over the intervals (-0.7, 0.76) and (0.76, ∞) . F(x) > 0 over the intervals (-0.7, 0.76) and (0.76, ∞) is the correct statement [Fourth choice].
About a Graphed Function
The function graph of an object F stands for the set of all points in the plane that are (x, f(x)). The graph of f is also known as the graph of y = f. (x). The graph of an equation is thus a specific example of the graph of a function. A graphed function is a function that has been drawn out on a graph.
It is evident from the attached graph that the supplied function exceeds 0 for the following range:
-0.7 < F(x) < 0.76
And, 0.76 < F(x) < ∞
As a result, the intervals for which the given graphed function, F(x) is greater than 0 are as follows,
(-0.7, 0.76) and (0.76, ∞)
