Answer:
x = 49
The equation does have a solution
Step-by-step explanation:
The sqrt of x = 7, does have a solution. Simply remove the radical, and raise each side by the index of the radical.
In more basic terms, what number has the sqrt of 7? 7^2 is equal to 49!
Answer:
y= -x
Step-by-step explanation:
<u>slope- intercept form</u>
y= mx +c, where m is the slope and c is the y-intercept.
Given that the slope is -1, m= -1.
Substitute m= -1 into the equation:
y= -x +c
To find the value of c, substitute a pair of coordinates into the equation.
When x= 2, y= -2,
-2= -2 +c
c= -2 +2
c= 0
Thus, the equation of the line is y= -x.
