*Hint: When the slope of a line is perpendicular, it would have the negative reciprocal.
First, let's simplify this equation into y = mx + b format.
y - 3 = 5(x - 4)
y - 3 = 5x - 20
y = 5x - 17
Since 5 is the slope of this equation, the negative reciprocal would be -1/5.
Answer: -1/5
5 trumpet players
let s represent saxophone players and t trumpet players
thus t = s - 10 → ( 10 less than saxophone players)
also s = 3t = 3( s - 10)
solve s = 3( s - 10)
s = 3s - 30
subtract s from both sides of the equation
0 = 3s - s - 30
0 = 2s - 30
add 30 to both sides
30 = 2s
divide both sides by 2
= s ⇒ s = 15
number of trumpet players = 15 - 10 = 5
For each power of ten , the number of zeros written in the product is the same as the number of exponents.
1 yard= 36 inches
10 yards* 36= 360 inches.
360 inches= 360 inches
So, 10 yards and 360 inches are equal.
