Hopefully this is the correct answer! but your expression would be: y=40x+30
and if he drove for 5hrs then you would plug in 5 for your x value so it would be y=40*5+30 and 40*5 is 200.(the star means multiplying) then add 30 to get a total of $230
so the expression is: y=40x+30
and if he drove for 5hrs then he sould make a total of: $230
hopefully that helped and was the right answer :)
Answer: you can approximate any variable in math by looking at the variables in the equation and working the problem through ur head or in paper
Step-by-step explanation:
Answer:
0.35
Step-by-step explanation:
P(0) = 348/1000
0.348
0.35 to the nearest hundredth
Answer:
y=4x+2 or f(x)=4x+2
Step-by-step explanation:
This is because the equation format for a line is y=mx+b, the slope is m and the y-intercept is b. So all you have to do is fill it out to get y=4x+2. Or the other way I listed the equation is right too. Hope this helps!
