Answer:
y = 1/x+2 + 3
Step-by-step explanation:
x = -2
y = 3
Some are
y-2=-3x
y+3x=2
3x=2-y
Answer:
(x-7) (x^2-5)
Step-by-step explanation:
x^3-7x^2-5x+35
Factor out an x^2 from the first two terms and -5 from the last 2 terms
x^2 (x-7) -5(x-7)
Factor out (x-7)
(x-7) (x^2-5)
AVERAGE between 90 and 100%
means not including 90 and 100% but not including 90 or 100%
average=(sum of values in set)/(how many values in the set)
so
4 exams, so there are 4 values
average=(sum)/4
the sum is the known+unknwon
sum=76+99+86+x
so
90<span><</span>average and average <span><</span>100
or
90<span><</span>average<span><</span>100
lets say average=a
a=sum/number
a=(76+99+86+x)/4
90<(76+99+86+x)/4<100
90<(76+99+86+x)/4 and (76+99+86+x)/4<100
solve each for x and find intersection
90<span><</span>(76+99+86+x)/4
times 4 both sides
360<span><</span>261+x
minus 261 both sides
99<span><</span>x
(76+99+86+x)/4<u><</u>100
times 4 both sides
261+x<u><</u>400
minus 261 both sides
x<u><</u>139
so
99<u><</u>x<u><</u>139
since max score is 100
99<u><</u>x<u><</u>100
interval notaion is
[99,100]
answer is 2nd one
Answer:
50%
Step-by-step explanation:
you can do ((1/6)/(1/3))*100=50% or (((1/3)-(1/6))/(1/3))*100%=50%
