X^2 + 4x + 8 = 0
( x + 2 ) ( x + 2 ) = 0
i am a mathematics teacher. if anything to ask please pm me
The relationship between Sabir and calories he burns can be modeled using a linear function given by:
y=ax+b
where
a=slope
b=y-intercept
from the graph, the slope will be given as follows:
taking points (3,15) and (12,60)
a=(60-15)/(12-3)=5 calories/minute
thus using the slope and a point (3,15) the equation will be:
a(x1-x)=(y1-y)
plugging the values we obtain:
5(x-3)=y-15
5x-15=y-15
thus
y=5x
thus the equation is:
y=5x
The all go over 18 so put them all over 18
16/18+12/18+3/18=31/18
31/18 or 1.722222222........
<span>16.66=16 <span>33/50 should be the answer

-3^6 = -729
-729 +(-4+7)(2)
-729 +(3)(2)
-729 + 6
-723
<em>hope it helps :)</em>
(ps: the result of -3^6 is not +729, the expression that would give this result is (-3)^6
