Answer:
15x + 14y = -18
Step-by-step explanation:
slope = (6 - -9)/(-8 - 6) = 15/-14
y = mx + b
6 = -15/14(-8) + b
6 = 60/7 + b
b = -18/7
y = -15/14x - 18/7
15/14x + y = -18/7, multiply everything by 14
15x + 14y = -18
Answer:
It should be -5/2 for the points (-6,8) (-16,33)
Step-by-step explanation:
area = width * length
or
A = W * L
55 = W * (W+6)
solve for width:
0 = W^2 + 6W - 55
this is a quadratic and has two solutions -11 and 5
a length can only be non-negative so discard -11.
width W = 5 miles
now the length is 5+6 = 11 miles
If they are 35% off, then u r actually paying 65%....
65% of 82.88.....turn percent to a decimal...." of " means multiply....
0.65(82.88) = 53.87 <== sale price
Step-by-step explanation:
90-2x + 3x + 60 = 180
90 + x + 60 = 180
x + 150 = 180
x = 30°
