Answer:
Step-by-step explanation:
Assume this is function is a straight line, consider the equation of the straight line: 
To find the gradient of the equation, we use any two coordinates from the table. 
We substitute the value of m in the equation:
To find c, we use the leftover coordinates, (4,0) in the equation above:
Substitute this value of c in the equation to get the function:
Answer:
x≤50
Step-by-step explanation:
100-3x≥-50
subtracting 100 at both side on inequality
-100+100-3x≥--50-100
-3x≥-150
Dividing both sides by 3
-3x/3≥-150/3
-x≥--50
Adding 50 on both sides
-x+50≥-50+50
-x+50≥0
Adding x on both sides
-x+x+50≥0+x
50≥x
so,
x≤50
6 = x + 2
Subtract 2 from both sides
6 - 2 = x + 2 - 2
4 = x
20 x 10 + 50 = m(ike)
15 x 10 + 50 = c(hris)
200 + 50 = 250
150 + 50 = 200
250 + 200 = 450
450 is 50 less than 500, so no. They do not have enough money for the trip.
