Step-by-step explanation:
the given function: 
Where C = cost (in dollars) and x is the number of miles you drive the truck.
when we compare the given function by slope- the intercept form y=mx+b, what we get is
Slope m = 0.5 whose fraction can be written as 
And y-intercept b =70.
for us to be able to graph it, we need to plot y-intercept from 70 and then plot some more points by applying or increasing the points by
the shaded lines on the graph indicates the given function.
cost is at $70 for 0 number of miles. travelled.
Thus;
the Domain: x≥0 and Range : 
≥
Answer:
3:2
Step-by-step explanation:
Answer:
He is not correct, the answer is All Real Numbers.
Step-by-step explanation:
When two lines are right on top of each other, the solution set is All Real Numbers that are on both lines because the solution set is the point(s) at which the lines overlap.
4)
12/16=21/b
multiply both sides by b
(12/16)b=21
now multiple both sides by (16/12)
b = 21 (16/12) =28
5)
rate is distance / time or time/distance
train travels 279 km per 1.5 hr =270/1.5
or
1.5 hr per 270 =1.5/27p
answer choice a and c matches that.
looking at choice C...270km/1.5hr=5hr/270km
looking at choice A.. 1.5hr/270km=5hr/k km
the units don't match for choice C so the
right answer is A
6)
1.5/270=5/k
multiply both sides by k
(1.5/270)k=21
now multiple both sides by (270/1.5)
k = (270/1.5)21= 900
7) 75 points per 6 game
75 points / 6 games
75/6=P/20
multiply both sides by 20
(75/6)20=P
P=250
4 colour needed for this…i think
