I think its d as
300=br
280=dvd&br
But there's 320 ppl so 320-280=40
Answer:
-9
-2
1
-10

Step-by-step explanation:
Just follow the equation left to right
Answer:
5/12
Step-by-step explanation:
Divide both numbers by the least common multiple. In this case it's 5.
25/5=5
60/5=12
If the number is 3.8333333.... then
X=3.83333....
10X = 38.3333.....
10X - X
38.3333....
- 3.8333....
= 34.5
so 9X = 34.5
X = 34.5/9
Multiple both top and bottom by 2 to get rid of decimal.
69/18
Normalize it to get rid of improper fraction.
3 15/18
Simplify
3 5/6
If the number is 3.838383838383.... then
X = 3.83838383...
100X = 383.83838383...
100X - X = 99X
383.83838383...
3.83838383...
380
99X = 380
X = 380/99
X = 3 83/99
The vertex is at (2, 5).
To find the vertex, we first find the axis of symmetry; this is given by
x = -b/2a
For our equation, b = -16 and a = 4:
x = -(-16)/2(4) = 16/8 = 2
We substitute this back into our equation:
y = 4(2)² - 16(2) + 21 = 4(4) - 32 + 21 = 5
Therefore the vertex is at (2, 5).
