Answer:i think you have to equal them to each other
Step-by-step explanation:
The distance from a point to a line is
distance(ax+by+c=0,(x0,y0)) = abs(ax0+by0+c)/sqrt(a^2+b^2)
So first convert the formula for the line to standard form
5x+2y=4
5x+2y-4=0
a=5, b=2, c=-4, x0=15, y0=-21
abs(5*15+2*(-21)-4)/sqrt(5*5+2*2)
= abs(75-42-4)/sqrt(25+4)
= 29/sqrt(29)
= sqrt(29)
= 5.385165 (approximately)
Answer:
48 pounds per square inch
Step-by-step explanation:
d = (1/2)n + 26
d = 50feet
50 = (1/2)n + 26
Subtract 26 from both sides
24 = (1/2)n
Multiply both sides by 2
48 = n
The slope-intercept form: y = mx + b.
The standard form: Ax + By = C.
We have:
<em>multiply both sides by 3</em>
<em>subtract 2x from both sides</em>
<em>change the signs</em>
<em>multiply both sides by (-4)</em>
<h3>Answer: B and C.</h3>
A. 3x - 2y = 4 - NOT
D. 2(x + 6) = 3y → 2x + 12 = 3y → 2x - 3y = -12 - NOT
E. 2x - 3y = 4 - NOT
