Step-by-step explanation:
-5y + 4 = -11 Get rid of the numbers to get y alone.
-5y +4 minus 4 = -11 minus 4 Here you are removing the 4 from the left
-5y = -15 Now you will have to get rid of the -5
-5y/(-5) = -15/(-5)
y = 3
Answer:
y = 3
Step-by-step explanation:
-5y + 4 = -11

a) This problem involves 8-digit binary strings such as 10011011 or
00001010.
i How many such strings are there?
ii. How many such strings end in 0?
iii. How many such strings have l's for their second and fourth digits?
iv. How many such strings have l's for their second or fourth digits?
b) Find how many 9-digit numbers can be made from the digits 1, 2, 3, 4, 5, 6,
7, 8, 9 if repetition is not allowed and all the odd digits occur first (on the
left) followed by all the even digits.
c) How many permutations of the letters A, B, C, D, E, F, G are there in which
the three letters ABC appear consecutively, in alphabetical order?
Answer:
a)
i) With an eight digit binary number, there are 2⁸, or 256 possible combinations.
ii) Each digit is set to 1 or 0 for exactly half of all combinations. This means that half of all strings, or 256 / 2 = 128 strings end with a zero.
iii) 3/4, or 128 + 64 = 192 of the combinations have a 1 for either the second or fourth digit. If you consider:
Half of all digits will have the second bit set to 1
Half of all digits will have the fourth bit set to 1
Half of those will overlap
Then that's half the digits, plus half the digits, minus half of half the digits. 1/2 + 1/2 - 1/4 = 3/4
iv) This is a duplicate of iii, so again, 192
b) If we're allowed to repeat the usage of the digits, then answer would be the number of values available to the power of the number of digits used. We're allowed six distinct digits, so the total combination of 9 digit numbers would be 6⁹, or 10077696
c) In this case we can look at it simply as permutations of the set {"ABC", "D", "E", "F"}, which gives us 4! which equals 24

Answer:
it's true. because it has more type of sums and head pain will come
Answer:
When two equations have the same slope but different y-axis, they are parallel. Since the two equations never intersect, the system has no solutions.

The function Y=4.75+2.20(X-1) can be used to determine the cost in dollars for a taxi ride in Houston, TX. What is the rate of change of the cost in dollars with respect to the number of miles?
Answer:
2.20 dollars/mile
Step-by-step explanation:
Given the function:
y = 4.75 + 2.20(x-1)
Before we get the rate of change of the cost, we need to write the expression in the form y = mx+c where;
m is the rate of change of the cost
From the function given:
y = 4.75 + 2.20(x-1)
Open the parenthesis
y = 4.75 + 2.20x -2.20
y = 2.20x + 2.55
On comparing with the standard
m = 2.20
Hence the rate of change of the cost in dollars with respect to the number of miles is 2.20 dollars/mile

Suppose a friend tells you she paid a total of $20,500 for a car, and you’d like to know the car’s list price (the price before taxes) so that you can compare prices at various dealers. Find the list price of the car if your friend bought the car in:
Roswell, where the sales tax is 6.5%
Given :
Total amount paid for the car is, A = $20,500.
Sales tax is 6.5%.
To Find :
The list price i.e. price without tax.
Solution :
Let, list price is P.
P = A - 0.65A
P = A( 1 - 0.65 )
P = 20500×( 1 - 0.065 )
P = $19167.5
Therefore, the list price of car is $19167.5 .
