Answer:
4+x=-3+2x
4+3=2x-x
7=x
9x=9*7
=63
Step-by-step explanation:
Answer:
7 markers cost $8.95
Step-by-step explanation:
9x = 11.50
x = 11.5/9 = 1.278
Therefore, 7 markers, or 7x = 7(1.278) = 8.946
Answer:
The value of b is -3 and m is 0.
Step-by-step explanation:
You have to substitute the coordinates into both equation in order to find m and b value :
Find m,
![y = mx + 3](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2B%203)
At (2,3),
![3 = m(2) + 3](https://tex.z-dn.net/?f=3%20%3D%20m%282%29%20%2B%203)
![3 - 3 = 2m](https://tex.z-dn.net/?f=3%20-%203%20%3D%202m)
![2m = 0](https://tex.z-dn.net/?f=2m%20%3D%200)
![m = 0](https://tex.z-dn.net/?f=m%20%3D%200)
Find b,
![y = 3x + b](https://tex.z-dn.net/?f=y%20%3D%203x%20%2B%20b)
At (2,3),
![3 = 3(2) + b](https://tex.z-dn.net/?f=3%20%3D%203%282%29%20%2B%20b)
![b + 6 = 3](https://tex.z-dn.net/?f=b%20%2B%206%20%3D%203)
![b = 3 - 6](https://tex.z-dn.net/?f=b%20%3D%203%20-%206)
![b = - 3](https://tex.z-dn.net/?f=b%20%3D%20%20-%203)
The mode for this question is <u>0</u>
<h3>Mode</h3>
In a set of numbers, the mode is the number that occurs most often. In other words, it measures how frequently a particular number occurs within a set of numbers. It is a type of average, like its counterparts, the median and mean.
To find the mode of a set of numbers,
- List the set of numbers in ascending or descending order, including any duplicates
- Count the number of times each number in the set of numbers occurs. The number that occurs the highest number of times is the mode of the set of data
