Answer: 11/12
Step-by-step explanation:
1. To solve this problem you can transform the mixed numbers given in the problem to fractions, as you can see below:
3 2/3=(3*3+2)/3=11/3
2 3/4=(4*2+3)/4=11/4
2. Now you must make the substraction of the fraction:
11/3-11/4=11/12
3. Therefore, the answer is 11/12
I used to shovel snow for $5 an hour.
If ' t ' was the number of hours I spent shoveling somebody's driveway,
then ' 5t ' was the number of dollars he owed me for the job.
' t ' didn't even have to be a whole number. It worked fine with any number.
Explanation:
using the parabola formula:
y = a(x-h)² + k²
vertex = (h, k)
We are given a parebola equation of: y = x²+9
comparing both equations to get the vertex:
y = y
a = 1
(x-h)² = x²
x² = (x + 0)²
(x-h)² = (x + 0)²
h = 0
+k = +9
k = 9
The vertex of the parabola as (x, y): (0, 9)
