Answer:
-1/5
Step-by-step explanation:
slope formula:
m = y₂ - y₁ / x₂ - x₁
Two points are given:
(-5, -5) (5, -7)
m = -7 - (-5) / 5 - (-5)
m = -2 / 10
m = -1/5
<h3>I'll teach you how to solve 4x^2-25<0</h3>
-------------------------------------------------
4x^2-25<0
Add 25 to both sides:
4x^2-25+25 < 0+25
Simplify:
4x^2 < 25
Divide both sides by 4:
4x^2/4 < 25/4
Simplify:
x^2 < 25/4
whole sqrt -25/4 < x < whole sqrt 25/4
whole sqrt 25/4= 5/2
-5/2 < x < 5/2
Your Answer Is -5/2 < x < 5/2
