Alright, so let's figure this out...
The total miles driven was 81. Let's go ahead and see how many times 81 goes into 4!
<em>81 / 4 = 20.25</em>
Her average was 20.25 mph. =)
<span>diff(x^2-11*x+24, x) = 2*x - 11
solve(2*x-11 = 0)
x = 11/2
y = (11/2)^2-11*(11/2)+24 = - 25/4
Vertex = (11/2, - 25/4)</span>
(3x+4)(2x+1)
If the question asks you to find roots/solutions:
3x + 4 = 0
3x = -4
x = -1.33333333
2x + 1 = 0
2x = -1
x = -0.5
Answer:
4/9 is greater.
Step-by-step explanation:
4/9= .4444444... repeating
.4444444∞>.4
I hope this was helpful, have a lovely day!!!
