Let f(x)=2x-1 and g(x)=1/x. Find the value of f(g(7))
netineya [11]

Answer:

-5/7

Step-by-step explanation:

We need to find g(7) first

All we have to is plug 7 in the place of x

g(7) = 1/7

Now we have f(1/7) = 2x - 1

f(1/7) = 2(1/7) - 1

f(1/7) = 2/7 - 1

Don't forget about common denominators

2/7 - 7/7 = -5/7

How do you solve the equation<br> x-2y-1=0<br> y-5x+14=0
Tcecarenko [31]

The solution is x= 3 and y = 1

Step-by-step explanation:

Given equations are:

x-2y-1 = 0\ \ \ \ Eqn1\\y-5x+14 = 0\ \ \ \ Eqn2

From equation 1:

x = 2y+1

Putting in equation 2:

y - 5(2y+1)+14 = 0\\y-10y-5 +14 = 0\\-9y-5+14 = 0\\-9y+9 = 0\\-9y+9-9 = 0-9\\-9y = -9

Dividing both sides by -9

\frac{-9y}{-9} = \frac{-9}{-9}\\y = 1

Putting y = 1 in equation 1:

x - 2(1)-1 = 0\\x -2-1 = \\x-3 = 0\\x-3+3 = 0+3\\x = 3

Hence,

The solution is x= 3 and y = 1
