it's called the distance formula. The square root of (-5-7)^2+(-1-(-6))^2
This simplifies to the square root of -12^2+5^2, or the square root of 144+25.
144+25=169.
the square root of 169 is 13
Answer:
y= -1/4x +9/4
Step-by-step explanation:
I did'nt know which form you needed so I just did Slope-Intercept
Both 9/3 and 54/18 come out to 3, so your answer is:
18:54
Answer:
A.
Step-by-step explanation:
81 - 49y^2 = (9 - 7y)(9 + 7y)
FOIL the equation.
(9 - 7y)(9 + 7y)
81 + 63y - 63y - 49y^2
81 - 49y^2
Ed : (0,205)(4,197)
slope(m) = (197 - 205) / (4 - 0) = -8/4 = -2
y = mx + b
slope(m) = -2
(0,205)...x = 0 and y = 205
time to sub
205 = -2(0) + b
205 = b
equation is : y = -2x + 205...so Ed loses 2 lbs per week
Eric :
y = -1.5x + 200...so Eric loses 1.5 lbs per week
when they started, Ed weighed 205 lbs and Eric weighed 200 lbs
* of the two, Eric loses fewer lbs per week. When the two began their respective weight-loss programs, Ed was heavier by 5 lbs.
