Now, if x = 300 miles, then
y= 1/20*300 + 35
y = 15 + 35
y = 50, therefore it would cost $50.00 to drive the rental car 300 miles.
Answer:
63
Step-by-step explanation:
x = # in ones place
y = # in tens place
x + y = 9
y = x - 3
substitute:
x + x-3 = 9
2x - 3 = 9
2x = 12
x = 6
y = 3
Answer:
11/10
Step-by-step explanation:
4\5 + 3/10
U need to make the denominator the same. 10 is a multiple of 5. to get 10 u times by 2
so 4\5 times by 2 =8/10 whatever you do to the denominator you do top. now you add the numerators 8+3= 11 so ur answer is 11/10
Answer is 0.7 degrees celcius per minute
Explanation:
given that T(t) = 42-0.7t
We have to find the rate of drop of temperature.
For that we find drop of T in 1 minute
Consider T(t) for t minutes and t+1 minutes
T(t+1) = 42-0.7(t+1)
T(t) = 42-0.7t
Difference i.e. drop in temperature in one minute
= T(t+1)-T(t)
= 42-0.7(t+1)-(42-0.7t) =-0.7
Hence drop per minute = 0.7 degree celcius.
Answer:
D
Step-by-step explanation:
it's the only one where the y of each point has a linear (even if constant) trend, the others go up and down
