Step-by-step explanation:
(i) 5 ≤ 2x − 4 ≤ 8 add 4 to all three expressions
9 ≤ 2x ≤ 12 divide by 2
9/2 ≤ x ≤ 6
(ii) −10 < (4 −3y)/− 5 ≤ 4 multiply all sides by -5
-20 ≤ 4 - 3y < 50 subtract 4
-24 ≤ -3y < 46 divide with -3
-46/3 < y ≤ 8
Answer:
Step-by-step explanation:
Here, given:
Now, here to find the values of 
As we know: 
Now, substituting x = 4 in f(x):
Now, substituting x = 1/2 in g(x):

Hi,
c(x) is a linear function, if you graph it, you obtain a straight line.
The slope is the coefficient of x, therefore the slope is 2.
When the ride starts (x = 0), the start cost is 4 dollars (or whatever the currency is), then every minute spent on the moving taxi, as many as 2 dollars need to be paid to taxi driver.
I hope these help.

Answer:
the answer is D.
Step-by-step explanation:
- First get x on one side by adding 10x on both sides. that leaves you with 18x
- subtract 20 on both sides. that leaves you with 36
- divide 36 by 18.
I hope i helped
