What is the difference between –11x – 2 and 13x + 5?
24x + 7
-24x + 7
24x + 3
-24x - 7
____________________________
1.) Find the opposite of 13x + 5:To find the opposite of 13x+5, find the opposite of each term.[tex]13x=-13x[/tex][tex]5=-5[/tex]- We do this because when solving this they are in parenthesis, so you must get rid of the parenthesis by turning them negative.
Equation at the end of Step 1:
[tex]-11x-2-13x-5[/tex]2.) Combine −11x and −13x:[tex]-11x+-13x=-24x[/tex]- We do this since we can only have on variable at the end of the problem, so you just combine them if they have the same variable base.
Equation at the end of Step 2:
[tex]-24x-2-5[/tex]3.) Subtract 5 from −2:[tex]-2-5=-7[/tex]- We do this because we need one number left over to get a simplified version of this equation.
Equation at the end of Step 3:
[tex]-24x-7[/tex]____________________________

Juanita is buying a cover for her motorcycle which has a length of 7.5 feet if the covers are only sold in whole foot increments what size covers should Juanita buy
Answer:
Size of the cover should Juanita buy is 8 feet.
Step-by-step explanation:
Given: The length of the motorcycle is 7.5 feet.
To find: The size of the cover of motorcycle.
The length of the motorcycle is 7.5 feet. But the covers are only sold in whole foot increments.
So, Juanita should buy 8 feet long cover for motorcycle.

Write an
explicit formula for An, the nth term of the sequence 7, -42, 252, ....
Answer:
[tex]A_n = 7(-6)^{n-1}[/tex]
Step-by-step explanation:
Key skills needed: Explicit formula, Geometric sequence
1) This is a geometric sequence, meaning a constant (like 6 or 3.5) is being multiplied to every term. First we need to find the constant.
This can be done by doing -42 ÷ 7 or 252 ÷ -42
-42 ÷ 7 equals -6.
252 ÷ -42 also equals -6.
2) This means that constant is -6.
3) The general form for an explicit formula of a geometric sequence is:
[tex]a_n = a_1(r)^{n-1}[/tex]
--> r means the constant (or common ratio) that is being multiplied.
--> [tex]a_1[/tex] means the first term
--> [tex]a_n[/tex] means the "nth" numbered term (so [tex]a_3[/tex] is the 3rd term, [tex]a_{10}[/tex] is the 10th term and so on).
--> [tex]n-1[/tex] is just the "n" in [tex]a_n[/tex] minus 1.
4) We can use this formula to create an explicit formula for the geometric sequence in the problem.
--> [tex]r = -6[/tex] (Since we got -6 as the constant/common ratio).
--> [tex]a_1 = 7[/tex] (Since 7 is the 1st term)
This means that our formula would be --> [tex]A_n = 7(-6)^{n-1}[/tex]
Hope you understood and have a nice day!! :D

You are trying to decide whether to use Uber or Lyft during a vacation. Uber charges $3 to pick up plus an additional $0.25 for each mile driven. Lyft does not charge to pick up but they have a rate of $0.75 for each mile driven.
Let x = the number of miles traveled and y = the total cost for the trip.
Answer:
Uber: y = .25x + 3
Lyft: y = .75x

Boris rides around a 800 metre track recording his speed each time. In
the three laps he recorded 49 secs, 53 secs and 48 secs. What was his
average time per lap?
Answer:
The easiest way to work out average times is to convert them all to seconds. 60 secs makes 1 min etc. Add all the seconds. Then divide the sum by the number of entries, hope this works.

Which set of numbers is arranged in increasing order? A. , , , B. , , , C. , , , D. , , ,
Answer: Option B.
Step-by-step explanation:
By an online search, i found that the options are:
A: (123873, 24765, 25000, 5678)
B: (16287, 16728, 16827, 16872)
C: (98782, 98728, 98287, 98278)
D: (78082, 78802, 78208, 78028)
The numbers will be arranged in increasing order if the difference between all the pairs of consecutive numbers in the set is positive (where the order of the numbers if from left to right):
For example, for the set A the differences are;
1) 24765 - 123873 = -99108
The difference is negative, then the second number is smaller than the first one, then the numbers are not arranged in increasing order.
Now let's see with set B:
1) 16728 - 16287 = 441
2) 16827 - 16728 = 99
3) 16872 - 16827 = 45
All the differences are positive, then the numbers on this set are arranged in increasing order.
We could easily see that in sets C and D the numbers are not arranged in increasing order, in set C the second number is smaller than the first one.
and in set D the third number is smaller than the second number.

Which is the correct equation for the graph of f(x), a transformation of the graph of g(x) = log2x? A. f(x) = -log2(x + 2) B. f(x) = log2(x − 2) + 2 C. f(x) = -log2x + 2 D. f(x) = log2x − 2
The equation of the function f(x) is: f(x) = log2(x − 2) + 2 option (B) f(x) = log2(x − 2) + 2 is correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a parent function:
g(x) = log₂x
Transformation:
g(x) → g(x) + 2
G(x) =log₂x + 2
The function will shift upside by 2 units.
G(x) → G(x-2)
f(x) =log₂(x-2) + 2
The function will shift right side by 2 units.
Thus, the equation of the function f(x) is: f(x) = log2(x − 2) + 2 option (B) f(x) = log2(x − 2) + 2 is correct.

Given that x^2 - y^2 = 45 and x + y = 9, find the values of x and y.
Answer:
x = 7
y = 2
Step-by-step explanation:
x² - y² = 45
(x+y) (x-y) = 45
x + y = 9 (known)
9 x (x-y) = 45
x - y = 5
y = x-5
x + (x - 5) = 9 (substitute)
2x = 14
x = 7
y = 2
