The second choise is the best choice
Answer:
There are 2 solutions: x = -5, 9.
Step-by-step explanation:
(x-2)^2 =49
Take square roots of both sides:
x - 2 = +/- 7
So x - 2 = 7 gives x = 9 , and
x - 2 = -7 gives x = -5.
We observe that the relationship between the variables is linear.
Therefore, we look for an equation of the form:
Where,
m: slope of the line
b ': intersection with the y axis
a: independent variable
b: dependent variable
The value of b 'occurs when a = 0.
We have then:
(See table)
Then, the value of the slope is found using the following formula:
Substituting values:
Rewriting:
Thus, the linear equation is:

Answer:
The equation is:
C.) 3a-b=10
Answer:
It's 37
Step-by-step explanation:
The given data set is ;
40,33,37,54,41,34,27,39,35
We arrange the data set in ascending order to obtain;
{27,33,34,35,37,39,40,41,54}
The median is the middle number {37}
