Answer:
205
Step-by-step explanation:
Given
N(t) = 100 + 15t is the equation of the relation.
We're asked to find N(7)
Taking a look at the question again and putting it side by side the equation
N(t)
N(7)
We can deduce that t = 7, and as such, solve for it in the equation given
N(7) = 100 + 15(7)
N(7) = 100 + 105
N(7) = 205
Therefore, the number of unread mails after 7 days will be 205
Take 2 coordinates
Slope'-
Equation in point slope form
- y-0=6/7(x-1)
- 7y=6x-6
- y=6/7x-6/7
Answer:
J (7, 10)
K (3, 2)
Formula for midpoint:
x - coordinate for M:
y - coordinate for M:
Therefore, M (5,6).
Hope this helps :)
Step-by-step explanation:
Answer:
D.
Step-by-step explanation:
Recall the slope is change of y over change of x which in this case the change in x is 1 while the change in y is 2 since the
's are going up by 2 while the
's are going up by 1.
So the slope is 2.
The one equation with slope 2 is D.
The answer is most likely D.

Answer:
19 Cars
Step-by-step explanation:
Write a linear equation:
y=7x+53
Y = Total money
X = cars parked
If we want to earn 186 dollars a day then sub y for 186 and solve x:
186=7x+53
186-53=7x
133=7x
7x=133
x=133/7
x=19
This means that he will need to park 19 cars a day to earn a total of 186 dollars in one day.
