There can only be two definite x-intercepts, so your goal it to find 2 numbers of x that, when plugged into the equation, give you the answer of 0. 1 is the first x-intercept(4-24+20 equals 0). The second one is 5 (100-120+20 equals 0). So the average is 3, so the axis of symmetry is 3 since 5+1=6, and 6/2=3
Honestly, there is an easier way to find the axis of symmetry. the equation would be -b/2a, where as b is the coefficient in the second part of the equation, while a is the first coefficient in the equation. -(-24) is 24, and 4*2=8, so 24/8=3
I hope I actually answered this the way you wanted. You asked for an equation, but I just answered the axis of symmetry with very simple equation initially and another equation
To find the percentage divide 10 by 100.. each chapter would make up 10% of the book.
Answer:
You need 3 cups of brown sugar for every 1 cup of white sugar.
Step-by-step explanation:
To find the smallest amount possible, divide both numbers by the smaller number. So, 6 (the amount of brown sugar) Divided by 2 equals 3, and 2 (the amount of white sugar) Divided by 2 equals 1.
Answer:
75% because the ratio is 1:4 so the probability of the next being minestrone is high.
