Answer:
Step-by-step explanation:
310 miles ÷ 5 hours = 62 miles per hour
403 miles ÷ 62 = 6.5 hours
ANSWER:
f(x)⁻¹ = (x+10)/2
WORKING OUT:
f(x) = 2x - 10
y = 2x - 10
*Replace all 'y' values with 'x' and vice versa*
x = 2y - 10
*Make y the subject of the equation*
2y = x+10
y = (x+10)/2
For number 25 it’s x=4 and for 26 it’s x=7
