X+ 5 If m(x)= x+1 and n(x) = x - 3, which function has the same domain as (mºn)(x)?

Mathematics

Semmy [17]3 years ago
8 0

Answer:

(m º n)(x)  =  x -2

Step-by-step explanation:

Here, in the given expression:

m(x)= x+1   and    n(x) = x - 3

To find :  (m º n)(x)

Now, solving for  (m º n)(x)

  (m º n)(x)  = m (n (x))  = m (x-3)

also,  m (x-3)  = (x -3) + 1  =  x -2

So, (m º n)(x)  =  x -2

The triangles are congruent. Find the length of each hypotenuse.
Zina [86]
If the triangles are congruents:
1) AC must be congruent with FE→AC=FE→y+3=2y+1→
y+3-y-1=2y+1-y-1→
2=y→y=2

2) CB must be congruent with ED→CB=ED→5x+7=6x+2y→
5x+7-5x=6x+2y-5x→7=x+2y→x+2y=7

Replacing y=2 in the equation above:
x+2y=7→x+2(2)=7→x+4=7→x+4-4=7-4→x=3

Then the lenght of each hypotenuse is:
CB=5x+7=5(3)+7=15+7→CB=22
or
ED=6x+2y=6(3)+2(2)=18+4→ED=22

The length of each hypotenuse is 22

12. A road race is 15 kilometers long. After the starting line, there are water stations every
zlopas [31]

Answer:

50

Step-by-step explanation:

Given

there is 1 water station at every 0.3 KM

If there are n water stations at every 0.3 KM

then KM covered by them = n*0.3 = 0.3n

given that total KM covered is 15 km

Thus,

0.3n = 15

=> n = 15/0.3 = 50

Thus, there are 50 water stations.
