2x + 4(x - 1) = 2 + 4x
2x + 4x - 4 = 2 + 4x
6x - 4 = 2 + 4x
6x - 4x = 2 + 4
2x = 6
x = 3........there is 1 solution
25 - x = 15 - (3x + 10)
25 - x = 15 - 3x - 10
25 - x = -3x + 5
3x - x = 5 - 25
2x = - 20
x = -20/2
x = -10.....there is 1 solution
4x = 2x + 2x + 5(x - x)
4x = 4x + 5x - 5x
4x = 4x......this has infinite solutions
learn this...
if ur equation ends in a variable equaling a number, then there is one solution.
if ur equation ends in something not equal, like 2 = 4, or 4 = 6, then there is 0 solutions.
if ur equation ends in something equal to something,(the same) like 2 = 2, or 4x = 4x, then there is infinite solutions
domain of the problem is -5 and the range is 4
Answer:
Step-by-step explanation:
radius=diameter/2
13/2
6.5
circumference of a circle=2πr
=2*3.14*6.5
=40.82 feet
=
Multiples of 13 from 1-50 : 13 , 26 , 39
total number from 1-50 : 50
no. of employees who is not a multiple of 13 : 50-3= 47
Probability = 47/50
I’m not sure if this is correct :( I tried hahaha
Answer:
Table A represents a function, but Table B does not represent a function.
Step-by-step explanation:
We have to select the correct option among the given 4 options after judging the given two tables attached to this question.
The first table shows that for each x values there is only one y value. Therefore, this is a function.
But in the second table shows that for each x value there are multiple y values since we are getting y = 1 and 2 for x = 5.
Hence, table B is not a function. it is just a relation. (Answer)
