Answer:
Uhm i think this is right
Step-by-step explanation:
y=mx+b
y=2
y=2x+2
3(x+5)=15
A.3
B.0
C.1/3
Answer:
x=0
Step-by-step explanation:
letter B
Answer:
B
Step-by-step explanation:
Take the three outaide the parentheses and distribute to both terms inside the parentheses. You would then get 3x+15= 15
subtract 15 from the left and right.
3x=0
Which means that x=0/3
So x=0
what are some strategies for rational numbers.
Answer:
Simplify
Step-by-step explanation:
Find the equation of the line shown.
Answer:
4y + x = 8
Step-by-step explanation:
firstly, we choose any 2 points on the line
point 1 = (0,2)
point 2 = (4,1)
x1 = 0, x2 = 4
y1 = 2, y2 = 1
from,
[tex] \dfrac{y2 - y1}{x2 - x1} = \dfrac{y- y1}{x- x1} [/tex]
[tex] \dfrac{1 - 2}{4 - 0} = \dfrac{y- 2}{x- 0} [/tex]
[tex] \dfrac{ - 1}{4} = \dfrac{y- 2}{x- 0} [/tex]
Cross multiplying,
-1(x) = 4(y - 2)
-x = 4y - 8
4y + x = 8
If it costs Melissa $8.20 to make a pie, how much should she charge for a pie? Round your answer to the nearest cent if necessary.
Answer:
$16.40
Step-by-step explanation:
The equation P = 2m + 15 represents the price P (in dollars) of a bracelet, where m is the cost of the materials (in dollars). The price of a bracelet is $115. What is the cost of the materials? Explain your reasoning.
Answer:
50
Step-by-step explanation:
115 = p
115 = 2m + 15
-15 -15
100 = 2m
/2 /2
50 = m

PLEASE HELPP WITH THIS QUESTION
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.

Step-by-step explanation:
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
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.

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

Find the value of x. Then find the angle measures of the triangle.
3x°
40°
Sum of angle
measures: 180°
Answer:
x=35°
3x= 105°
Step-by-step explanation:
[tex]40 + 3x + x = 180[/tex]
[tex]40 + 4x = 180[/tex]
[tex]4x = 180 - 40[/tex]
[tex]4x = 140[/tex]
[tex]x = \frac{140}{4} [/tex]
[tex]x = 35[/tex]
[tex]3x = 3(35) \\ 105[/tex]

how coordinates change when we add or subtract outside the function?
Answer:
if c is positive, the graph is shifted up. If c is negative, the graph is shifted down. Informally: Adding a positive number after the x outside the parentheses shifts the graph up, adding a negative (or subtracting) shifts the graph down.
