Answer:
y = x + 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
- 7x + 2y = 8 ( add 7x to both sides )
2y = 7x + 8 ( divide all 3 terms by 2 )
y = x + 4 ← in slope- intercept form
1 mile = 5,280 feet:
9 miles x 5280 feet per mile = 47,520 total feet per hour
1 hour = 3600 seconds.
Divide total feet by seconds per hour:
47,520 feet / 3600 seconds per hour = 13.2 feet per second.
Multiply feet per second by number of seconds for distance traveled:
13.2 feet per second x 15 seconds = 198 total feet.
Alright so what you are doing is getting the area of the whole triangle, and that formula is what you do so bxh is 5x12 and 5x12=60 then you need to divide 60 by 2 which is 30 so your answer will be
B 30m^2
