Step by step explanation
let x be the number of minutes and y be the total charges per month
A. Melissa's cell phone plan charges two cents a minute plus a $10 monthly fee.
y=0.02x+10
B. Sandra's cell phone plan charges seven cents a minute.
y=0.07x
C. Holly's cell phone plan charges five cents per minute. She also receives a $5 discount each month.
y=0.05x-5
D. Alicia's cell phone plan charges six cents per minute plus a $5 monthly fee.
y=0.06x+5
Andre and Elena are solving this system of equations.
Y=3x
Y=9x-30
Andre’s first step is to create a new system:
3y=9x
Y=9x-30
Do you agree with either first step?
A-both strategies work
B-only the first strategy works
C-only the second strategy works
D-neither strategies work.
Answer:
A-both works
Step-by-step explanation:
one can simply sub into the second equation from the first step's one and remove an unknown, making it easy to solve
For the function F(x) = 1/x+1 which of these could be a value of F(x) when x is close to -1?
Answer:
Option B, -10000
Step-by-step explanation:
Step 1: Find the number that would be valid
As the x value gets closer to -1, the y values go to positive and negative infinity. Therefore, the best value out of the options given would be -10,000 since it is the closest to negative infinity.
Answer: Option B, -10000

what two numbers multiply to -36 and add up to 5
Answer:
9 and -4
Step-by-step explanation:
Finding these 2 numbers can be found by guessing and checking. By doing this, it will get you the numbers 9 and -4.
First, test if they multiply to -36:
9(-4)
= -36
Then, check if they add up to 5:
9 + (-4)
= 5
So, 9 and -4 are the 2 numbers that multiply to -36 and add to 5

1101101+11011 in binary numbers please help
Answer:
The answer is 1000 1000
Step-by-step explanation:
In HEX, it would be 88.
In DEC, it would be 136.
In Oct, it would be 210.
Binary, how to add numbers together.
1101101
+ 11011
10001000
This is just like adding regular numbers together.
For example, when you add 88 to 55, this is what will happen
1(r)
88
+ 55
13(+1) 3
143
With binary, when 1 and 0 are added together, the result is 1. When 1 and 1 are added together, the result is 1 and 0 (1 being the "remainder", or the number that is carried over. This number is then added to the next part of the number when adding, just like in normal addition.

Write an
explicit formula for An, the nth term of the sequence 15, 8, 1, ....
Answer:
b(n) = 15 - 7(n - 1)
Step-by-step explanation:
15 is the y-intercept
-7 is the slope
Answer:
[tex]a_{n}[/tex] = 22 - 7n
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
8 - 15 = 1 - 8 = - 7
This indicates the sequence is arithmetic with explicit formula
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 15 and d = - 7 , then
[tex]a_{n}[/tex] = 15 - 7(n - 1) = 15 - 7n + 7 = 22 - 7n ← explicit formula

Sketch a 9 red counters and 4 yellow counters.How many zero pairs can you make?How many counters do you have after you remove the zero pairs? What do they represent
Answer:
36.75 and 1/6 ( 6 accounts equally distributed )
Step-by-step explanation:
Number of Red counters to be sketched = 9
Number of Yellow counters = 4
The number of Zero pairs that can be made = 36.75
When you remove the Zero pairs the number of counters you would have = 6 accounts ie. 1/6

Answer:
3/4 (0.75)
Step-by-step explanation:
sin r = 15/20 = 3/4 (0.75)
what is the y - intercept
Answer:
The y- intercept is 1
Step-by-step explanation:
Since the line crosses the y-axis at 1, the y-intercept is 1. Like the x-intercept. The line crosses the x-axis at um.. I would say about -1.5, so the x-intercept is -1.5.

Answer:1144.2 for question 5
Step-by-step explanation:
Brianna jogs 15 minutes more on Sunday than Saturday. She jogged 26 minutes on Saturday.
a.
How many minutes does she jog on Sunday?
Answer:
41
Step-by-step explanation:
15+26=41
Answer:
41 minutes
Step-by-step explanation:
If she jogged 15 minutes more on Sunday than Saturday, we can find how many minutes she jogged on Sunday by adding 15 to Saturday's amount:
So, add 15 to 26:
15 + 26
= 41
So, she jogged 41 minutes on Sunday.

help idk how to do math
use the distributive property
Answer:
Distributive property is when you multiply or add the numbers in the parentheses equally to the number outside the parentheses.
That probably isn't a good answer, here's what I found on google:
To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.
Step-by-step explanation:
I'll do #10 as an example:
(x-5)y
distribute the numbers- y(x)-y(5)
without the parentheses- yx-y5
you can't really get an answer by multiplying a number and a variable, or a variable and a variable, so you just leave them and take the parentheses.
Here's #11:
-4(2a-3b+c)
distribute the numbers- (-4*2a)-(-4*3b)+(-4c)
solve- -4*2= -8
-4*3= -12
-8a-(-12)b+4c
*I dunno how to use parentheses for negative numbers but what I did for distributing is pretty much the same thing
Hope this helps you.
Fill in the blank to complete the equation below. 99 + 33 = 11(?+3)
Answer:
? = 9
Step-by-step explanation:
you know 99 + 33 = 132 so you can substitute that: 132 = 11 (? + 3). im going to change ? into x for now: 132 = 11 (x + 3). then distribute the 11 so 132 = 11x + 33. then subtract 33 from both sides (99 = 11x) and divide both side by 11 (x = 9) and you get 9!
hope this helps!
