The answer should be
x = 7 or just 7
Hope it helped !!
If x is the number of calls he makes and y is the number of hours he works;
the total amount he charges is termed as C
C = (50 * x) + (25 * y )
C = 50x + 25y
25y = C - 50x
the 2 variables are not proportional.
For 2 variables to be proportional, they need to be in the form y = mx
Where m is a constant. When x increases, y too should increase by the same amount.
The question given x and y are not proportional. As the number of hours he works and number of calls he charges are not dependent on each other. Therefore the 2 variables are not proportional.
Answer:
B.80.85%
Step-by-step explanation:
The equation shows that the percent of school attendance depends on cloudy days, in a negative way, which means that the more cloudy days, the less the percentage of students that go to school.
- Particular, when there are 18 cloudy days, x takes a value of 18, x=18,
- This means that y= -1.2 (18) + 102.45 which equals 80.85%.
Yes good job!! the one you picked is correct
The remainder of f(x) = 7
Step-by-step explanation:
f(x) = 
Here 2x - 1 is a factor.
We will apply Factor theorem ( states that if (x-a) is a factor of f(x) then f(a) is the remainder)
Putting x = 1/2 in f(x) we will get the remainder.
f(1/2) = 2(1/2)^3 -5(1/2)^2 +8(1/2) +4
=7
