Answer:
3f+6
Step-by-step explanation:
To solve this, we combine like terms which are in this case 4f and f. 4f-9-f+15 is (4f-f)+(-9+15), which we simplify to 3f+6.
Answer:
The second option you listed: x + y = 4 gives the same line as H, and therefore renders infinite number of solutions (as many as every point on the line)
Step-by-step explanation:
We need to look for the equation that exactly matches the given one :
2 x + 2 y = 8
notice dividing both sides of this equation by "2" we get:
x + y = 4
SO this equation represents exactly the same line as 2 x + 2 y = 8 does, and therefore their graphs overlap completely
-5x-3=-23
Add 3 to both sides
-5x=-20
Divide both sides by -5
x=4
Final answer: x=4
Check:
-5(4)-3
-20-3
-23
-23=-23
True
it is a statistical question due to you having to collect data to answer this question, you'd have to collect data on how tall the giraffes are and i'm sure they all don't grow up to be the same height so there will be differentiations in heights of all.
12 * 3 = 36
Therefore your answer should be 36 miles.
