y-y1 = m(x-x1)
where: x1 = 1 y1 = 8 (given point (1,8) and m = -3
y - (8) = -3 (x - (1))
y - 8 = -3 (x-1)
y- 8 = -3x +1
Answer:
10.4 miles
Step-by-step explanation:
Write an equation for the total cost paid as a function of the # of miles driven:
L(x) = $6.75 + ($3.20/mile)x
and set this equal to $40.03 to determine the # of miles Lupita rode:
L(x) = $6.75 + ($3.20/mile)x = $40.03
Isolate the x term by subtracting $6.75 from both sides:
($3.20/mile)x = $40.03 - $6.75 = $33.28
Finally, divide both sides by ($3.20/mile):
x = $33.28 / ($3.20/mile)
= 10.4 miles
Lupita rode 10.4 miles in the taxi.
Answer:
-1
Step-by-step explanation:
m = -7 / 7 = -1 / 1 = -1
Answer:
r = -
Step-by-step explanation:
The n th term of a GP is
= a₁
where a₁ is the first term and r the common ratio
Here a₁ = 18 and a₆ = - , then
18 = - ( divide both sides by 18 )
= - ( take the fifth root of both sides )
r = = -
So you have
8 digits (number available) to form
3 digit numbers (number selected).
Using the formula
where a is the number of available digits, P is the permutation function and c is the number of digits to be selected.
The number of three digit numbers that can be formed =
=
336 <span>
