Answer:
The constant <em>a</em> is the scale factor on the parabola; positive <em>a</em> makes a CUP (concave up), which is the usual orientation. Negative <em>a</em> makes an upside-down parabola. Big <em>a</em> (in absolute value) makes a skinny parabola, small <em>a</em> a wider one.
<em>r</em> and <em>s</em> are the zeros of the quadratic function, the values of x that give y=0.
Answer:
22.99
Step-by-step explanation:
well you see when you multiply by 10 you just move the decimal to the left once
Subtract 15 from both sides
-35x> -14.65 or -14 13/20
Divide both sides by -35
When u divide both sides by a negative number, the sign switches
x< -14.65/-35
x< 0.418571 or as a fraction
x< 293/700
So the inequality will be
x<293/700
I know it looks confusing but I believe this is the correct answer...
