Answer:
[tex]t(x) = 4x - 2 \\ c(x) = x + 9 \\ c(t(x)) = (4x - 2) + 9 \\ = (4(2) - 2) + 9 \\ = 8 - 2 + 9 \\ = 6 + 9 = 15[/tex]
find the sum of all possible four digit numbers that can be formed using the digits 2,4,5,6,7 and 8 with no repeated digits
Answer:
2133120
Step-by-step explanation:
using 6 given digits, lets create a 4 digit number:
to choose the first number, you have 6 options. to choose the second number we have 5 options left. for the third number we have 4 options left. and for the fourth number, we have 3 options left.
6*5*4*3 = 360
with no repeats, 360 numbers can be formed.
this means that each number will occur 60 times each (360/6 digits)
so to find the sum:
60*(2+4+5+6+7+8) = 1920
but, we have one more thing:
In the thousands place, our sum of digits is multiplied by 1000; in the 100’s place, by 100; in the ten’s place, by 10; and in the one’s place, by 1. so:
1920(1000+100+10+1) = 1920*1111 = 2133120
The value of y is directly proportional to the value of x.
If y = 10 when x = 5, what is the value of the following.
a) find the value of y when x is equal to 4.
b) find the value of x when y is equal to 6
Answer:
a) find the value of y when x is equal to 4.
Step-by-step explanation:
Answer:
a) the value of y will be x=5 - 4= 1
therefore y=1
b) the value of x will be y= 10 - 6= 4
therefore x=4

While on vacation in Washington DC, the cab ride for the Dulles airport to the hotel is 15 miles. The
total cost of the cab ride was $25.50. The cabbie charges $1.50 per mile for the entire trip.
A. Write an equation to that can be used to determine how much a cab ride would cost anywhere in Washington DC.
B. What is the flat rate of the cab ride?
C. How much does it cost to travel 7 miles in a cab?
The equation that can be used to determine the cost of a cab ride is cost = $3 + ($1.50 x miles driven).
The flat rate of the cab ride is $3.
The cost of travelling 7 miles is $13.50.
The total amount that would be spent on the cab ride is a function of the price per mile, the total miles driven and the flat rate.
Total cost = variable rate + flat rate
variable rate = cost per mile x total miles driven
15 x $1.50 = $22.50
Flat rate = total cost - variable rate
$25.50 - $22,50 = $3
The equation to determine the total cost of a cab ride: $3 + $1.50m
Where m is the miles driven.
The cost of travelling 7 miles : 3 + (1.5 x 7) = $13.50
