Answer:
14.4
Step-by-step explanation:
To evaluate a variable expression means to find the value of the expression when the variable is (or variables are) ... 3(4)−2(5)=12−10=2 ... If there is only one variable in an expression, we don't always need to mention it: ... What is the variable expression for (2t+4)3+6(-5t)-(-8)? ... How do you evaluate 1.2g if g=77?
It's litterally called a community service... funny huh?
Answer:
8 movies or video games.
Step-by-step explanation:
Let x be the number of movies or video games on rent.
We have been given that Omar has a choice of belonging to a video club with a monthly fee of $12 and $1-a-day rental fee for any movie or game. We can represent the charges for x movies or video games for a member of club as: .
Omar can be a non-member and pay $2.50-a-day rental fee for any movie or game. We can represent the charges of a non-member for x movies or video games as: .
To find the number of movies for one day for the cost to be equal we will equate our both expressions.
Therefore, Omar must rent 8 movies or video games for one day for the cost to be equal between membership and non-membership.
By renting 8 movies or video games charges for membership will be: 8+12=20.
By renting 8 movies or video games charges for a non-membership be: 2.5*8=20.
Hence charges of renting 8 movies or video games are same for both membership or non-membership.
Answer:
f(x)=
Step-by-step explanation:
The given function is an exponential function .All the graphs will begin from second quadrant . The exponential graph crosses the ordered pair at (0,-1)
It then decreases slowly as it approaches y=-2.
The point (0,-1) lies on the graph:
Slope of perpendicular lines = opposite reciprocal
the slope of y = 2x - 17 is 2 or 2/1.
we using opposite reciprocal
opposite reciprocal a/b is -b/a
2/1 would change into -(1/2)
now, input the value x and y,
and the answer is c. y = -(1/2)x -3
hope this help
