Answer: Its a trick question
Step-by-step explanation:
I did this yesterday
Y=-x+8
gradient of the parallel line is the same as the gradient of the line given, which is -1
to find the y-intercept, sub the values (9,-1) into the equation we are finding which is y=-x+c
Answer:
t = 3
Step-by-step explanation:
Given
- 3 (t - 2) + 7t = 9t - 9 ← distribute left side and simplify
- 3t + 6 + 7t = 9t - 9
4t + 6 = 9t - 9 ( subtract 9t from both sides )
- 5t + 6 = - 9 ( subtract 6 from both sides )
- 5t = - 15 ( divide both sides by - 5 )
t = 3
Let f be the function with variable n, which gives the number of pictures left in the phone after deleting pictures for n-days.
So f(1) gives the number of photos left after 1 day of deleting photos
f(2) gives the number of photos left after 2 days of deleting photos
and so on.
f(1)=745-20
f(2)=745-20-20=745-20*2
f(3)=745-20-20-20=745-20*3
so clearly f(n)=745-20n
Answer:
the algebraic expression is f(n)=745-20n,
where n is the n'th day of deleting photos, and f is the number of photos left after n days of deleting.
