80 km because if the units number is smaller than five then you go to eighty but if the number is five or more you have to go to ninety but the number is smaller so i went to eighty.
Answer:The line goes through the points (4,-3) and (0,-2), so its gradient is (-2-(-3))/(0-4) = -1/4. The y-intercept is -2 because f(0)=-2. So the equation of the line is y = -1/4 x - 2.This can be represented by the linear function f(x) = (-1/4)x - 2. The composite function ff is given by ff(x) = f(-1/4 x - 2) = (-1/4)((-1/4)x - 2) - 2 = x/16 - 3/2.HOPE'S THIS HELP'S
Answer:
27
Step-by-step explanation:
So I dont really get the equation because its written confusingly but I will try my best.
1. √(2x+10) -6=2
2.√{2x+10}=8
3.√{2x+10}^2=8^2
4.2x+10=64
5.x=27
