X = 9 sorry if x isnt what youre looking for
2² - y - 5 = 0
Evaluate the power.
4 - y - 5 = 0
Calculate the sum or difference.
-1 - y = 0
Move constant to the right side and change its sign.
-y = 1
Change the signs on both sides of the equation.
y = -1
Answer: -7/2
Step-by-step explanation:
The Inequality which represents all possible values of x, such that the given expression is a positive value is :
The y-intercept which is the point at which x = 0 is; A: -10
<h3>How to find the y-intercept?</h3>
The general form of an equation of a line in slope intercept form is;
y = mx + c
where;
m is slope
c is y-intercept
We are given the slope;
m = -4
Now, the line passes through the point 0, -10. Thus;
(y - y1)/(x - x1) = -4
(y + 10)/(x - 0) = -4
y + 10 = -4x
y = -4x - 10
Thus, the y-intercept which is the point at which x = 0 is; y = -10
