Answer:
i think this is true because on a line graph nothing stays the same.
Step-by-step explanation:
If we start line graph on the viruses that are going around the number of deaths and cases would change every day and every second
You would reduce each of them down by dividing both the top and bottom by the same number, so 15/45 turns into 1/3
3/9 - 1/3
3/15 - 1/5
1/3
30/90 - 1/3
The only one that's different is 3/15
Answer:
a = 0
Step-by-step explanation:
3(4a+7)=5(2a+4)+1 Distribute 3 through the parentheses
- > 12a + 21 = 5(2a + 4) +1
5(2a + 4) +1 --> 10a + 20 + 1
12a + 21 = 10a + 20 + 1 --> 12a + 21 = 10a + 21 --> 12a = 10a
12a - 10a = 0 --> 2a = 0
Divide both sides of the equation by 2 --> a = 0
