Step-by-step explanation:
practical range = 8
vertical line test = 5
range = 3
domain = 2
relation = 1
function = 4
function Notation =6
practical domain=7
12/9 reduced in simplest form would be 4/3 or 1 1/3. You can pick which one you want to do :). They are both the same thing just one is an improper fraction and the other is a mixed number. I got this answer by dividing both the top and the bottom (The denominator and the numerator) by three.
For every 7 boys, there is one girl
So: 63/7 = 9
There are 9 girls.
11.) Since the standard coord. equation is "mx+b"
And since the "+b" portion is your y-intercept.
Your y-intercept would be the <span>$0.85 "for each topping"</span>
12.) Your equation needed is...
.75x+5 <span>≤ 14
x=12, meaning that she alone cannot ride more than 12 rides</span>
