The answer is 21 because 9+10=21 see im smart
The pressure of moving air is called wind
The slope of the given line is 5/4. The slope of a line perpendicular to the given line is the negative reciprocal of 5/4, or -4/5.
Using the point-slope form,
y - 5 = (-4/5)(x - 10).
This is the desired new line.
Note that mult. both sides by 5 removes the fractions:
5y - 25 = -4(x - 10), or 5y - 25 = -4x + 40.
Solving this for y: 5y = 25 - 4x + 40, or 5y = -4x + 65
Then y = (-4/5)x + 13 (answer)
Answer:
16
Step-by-step explanation:
8÷2(2+2)
From PEMDAS, we do the equation in the parenthesis first.
8÷2(4)
Since this is division and multiplication we go left to right.
4(4)
