D=4(9-c) and d=2(9+c)
d=36-4c and d=18+2c
Since d=d
18+2c=36-4c add 4c to both sides
18+6c=36 subtract 18 from both sides
6c=18 divide both sides by 6
c=3
So the speed of the current is 3mph
The correct answer is
g(f(1))
Plug 1 into the f function.
f(1) = 2(1) + 6
f(1) = 8
Now evaluate g(8)
g(8) = 8^2 + 6
g(8) = 70
Hope this helps!
So in short your answer is 70
Hello :
<span>4x - y =3........ ×3
2x+3y = 18
I'have : 12x-3y = 9
2x +3y = 18
</span><span>by the addition method : 14 x =27
</span> x = 27/14
4(27/14)-y = 3
y = 33/7
Answer:
x = 50°
Step-by-step explanation:
Recall that for a triangle, the exterior angle is equal to the sum of its two remove interior angles (also see attached for reference).
in our case, the exterior angle is given as 105° and its two remote interior angles are x and 55°
therefore
105° = 55° + x
x = 105° - 55°
x = 50°
Answer:
She will still need about 450$
Step-by-step explanation:
So from what I have learned, she will need to work in order to get the money, but even when she is working, she may have expenses to pay and she may not make it, but she will because she can do loans and when she earns the money from loans, then she can pay, then she may have left over money she can use while on trip.
