How many solutions does this system have? y = 3 x minus 5. y = negative x + 4. one two an infinite number no solution

AveGali [126]

Answer:

One

Step-by-step explanation:

It is given that,

y = 3x-5 ....(1)

y = -x+4 .....(2)

We can solve the above equations using substitution method. Put the value of y from equation (1) to equation (2) such that,

$3x-5 = -x+4\\\\3x+x = 5+4\\\\4x = 9\\\\x=\dfrac{9}{4}$

Put the value of x in equation (1) we get :

$y = 3x-5\\\\y = 3\times \dfrac{9}{4}-5\\\\y=\dfrac{7}{4}$

It means that the value of x is $\dfrac{9}{4}$ and the value of y is $\dfrac{7}{4}$ . Hence, the given equations has only one solution.

Which expression is equivalent to the following complex fraction? <br><br>(pls help me out)

const2013 [10]

Answer:

B. $\frac{-4x + 7}{2(x - 2)}$

Step-by-step explanation:

Simplify the given expression to determine its equivalent expression in the given options.

$\frac{\frac{3}{x - 1} - 4}{2 - \frac{2}{x - 1}}$

$\frac{\frac{3}{x - 1} - \frac{4}{1}}{\frac{2}{1} - \frac{2}{x - 1}}$

$\frac{\frac{3 - 4(x - 1)}{x - 1}}{\frac{2(x - 1) - 2}{x - 1}}$

$\frac{\frac{3 - 4x + 4}{x - 1}}{\frac{2x - 2 - 2}{x - 1}}$

$\frac{\frac{-4x + 7}{x - 1}}{\frac{2x - 4}{x - 1}}$

$\frac{-4x + 7}{x - 1} * \frac{x - 1}{2x - 4}$

(x - 1) cancels (x - 1)

$\frac{-4x + 7}{1} * \frac{1}{2x - 4}$

$\frac{(-4x + 7)1}{1(2x - 4)}$

$\frac{-4x + 7}{2x - 4}$

$\frac{-4x + 7}{2(x - 2)}$
