Area of a triangle equals 1/2 Bh
base = 2.5 height = 5
2.5 x 5 = 12.5/2 = 6.25
since there are 4 sides you multiply by 4
6.25 x 4 = 25
Now to do the bottom you multiply 2.5 x 2.5 = 6.25
6.25 + 25 = 31.25<----ANSWER
Hope this helps
All that's necessary is to add 4 to both sides of the equation. This gives
... y = 1/2(x -8) +4
If you like, you can simplify this by eliminating the parentheses and collecting terms.
... y = 1/2·x -4 +4
... y = (1/2)x
well, i believe the answer is each dollar= 1.6 pounds
Answer:
y=-3
Step-by-step explanation:
there is no slope so x will not be used in the equation it also crosses at -3
