Step-by-step explanation:
y = (x - 4)/x = x/x - 4/x = 1 - 4/x
c = 1
r = -4

Answer:
y = 3, y = 5, y = -1
Step-by-step explanation:
What you do is you substitute the x values into the x.
<em>y + 2(-1) = 5</em>
<em>y + -2 = 5</em>
y = 3
<em>y + 2(0) = 5</em>
y = 5
<em>y + 2(4) = 5</em>
<em>y + 6 = 5</em>
y = -1.
X intercept: y = 0
y= -3/4x -4
0 = -3/4 x - 4
4= -3/4 x
4 • -4/3 = x
-5.3 = x
y intercept: x = 0
y = -3/4 x -4
y = -3/4 (0) -4
y = -4
the points are (-5.3, 0) and (0, -4)
2x^2 - 11 = 87
2x^2 = 87 + 11 = 98
x^2 = 98/2 = 49
x = sqrt (49) = + or - 7
