Answer:
Step-by-step explanation: subtract 6 from both sides and then divide both by -3
Answer:
all work is shown and pictured
Y- intercept =-5
y-y1=m(x-x1)
y-(-1)=4(x-1)
y+1=4(x-1)
y+1=4x-4
y=4x-4-1
y=4x-5
Or
y=4x+b
-1=4(1)+b
-1=4+b
-1-4=b
-5=b. Y-intercept is -5
So cost=50+75t
so 200=50+75t
subtract 50 from both sides
150=75t
divide both sides by 75
2=t
$200=2 hours
50+75t=cost
300=50+75t
subtract 50 from both sides
250=75t
divide both sides by 75
10/3=t=200 mins=3hours 20 mins=$300
