Answer:
7y+5x=76
Step-by-step explan
A (-4,8) and B (6,3)
First find the slope;
m= (y2-y1)/(x2-x1)
m=(3-8)/(3+4)
m=-5/7
now using equation of line
y-y1= m(x-x1)
y-8=-5/7 (x+4)
y-8=(-5x+20)/7
7(y-8)= -5x+20
7y-56=-5x+20
7y+5x=20+56
7y+5x=76
Answer:
x = 135
Step-by-step explanation:
The three triangles are similar.
144/y = y/81
y^2 = 144 * 81
y = 12 * 9
y = 108
81^ + 108^2 = x^2
x^2 = 18225
x = 135
$15 x 4 hrs = $60 in wages.
$13.25 x 2CD's = $26.50.
$60 - 26.50 = $33.50 left
