the discriminant b^2 - 4ac when the equation is in the form of ax^2 +bx+c=0
13x^2-16x = x^2 -x
we need to get in it the standard form
subtract x^2 from each side
12x^2 -16x = -x
add x to each side
12x^2 -15x = 0
12x^2 -15x -0 =0
a=12 b=-15 c=0
b^2 -4ac
the discriminant = b^2
b^2 = (-15)2 = 225
Answer:
25.9 yd
Step-by-step explanation:
+
= 
+
= 
289 +
= 961
Subtract 289 on both sides
= 672
= 
nearest tenth
b = 25.9 yd
Your 3/5 - (1/3)x is an expression, not an equation. You must write out the entire equation in question:
"Identify the slope and y-int. of y = 3/5 - (1/3)x."
The y-intercept is obvious: It's 3/5.
The slope is (1/3).
