The zero product property tells us that if we have
xy=0, then we can assume that x and y both equal 0
so
(4k+5)(k+7)=0
we can assume that 4k+5=0 and k+7=0
so
4k+5=0
minus 5 both sides
4k=-5
divide both sides by 4
k=-5/4
k+7=0
minus 7 both sides
k=-7
k=-5/4 or -7
Answer:
64
Step-by-step explanation:
;)
the data are 1,6,8,8,8
If we remove 1 or 8, we can see that the mean is changed
since this quantity takes all values.
Median also change if we remove one value. If we remove
Y=mx+b
Distribute 3 to (x-1), 3x-3
y+9=3x-3
Subtract 9 on both sides
y=3x-12( the answer)
Hope this works !! Good luck
