There are 38 chickens and 16 cows.
38 times 2 equals 76 and 16 times 4 equals 64. 64 plus 76 equals 140.
Answer: d) 255 ≤ f(x) ≤ 340
Step-by-step explanation:
The function
f(x)= 8.5x
represents the amount of money that Steve earns given the number of hours, x, he works.
The dependent variable is the total amount that he earns, f(x) while the independent variable is the number if hours, x that he works. The range is the possible values of the dependent variable that satisfies the equation.
Steve works between 30 and 40 hours per week. This means that
the lowest amount that he earns is 8.5×30 = $255
The highest amount that he earns is 8.5× 40 = 340. Therefore, the range is
255 ≤ f(x) ≤ 340
Answer:
See below
Step-by-step explanation:
Mean: 
Median: 14, 18, 20, 22, 30, 38 -> (20+22)/2 = 21
Mode: No mode as all elements are of equal frequency
The hourly rate would be $14
Answer:
x=-5
Step-by-step explanation:
since the y's cancel out, set the first equation equal to the second and solve like you'd normally do.
