What is the solution to the system of equations below? Y=-1/4x+2 and 3y=-3/4x-6

fgiga [73]

Answer:

There are infinite solutions to the system of equations given

Solution:

The given equations given are,

$y=-\frac{x}{4}+2$ ------ (i)

$3 y=-\frac{3 x}{4}-6$ ---- (ii)

Now putting the value of (i) in (ii) we get,

$3 \times\left(-\frac{x}{4}+2\right)=-\frac{3 x}{4}-6$

$\Rightarrow-\frac{3 x}{4}+6=-\frac{3 x}{4}-6$

$\Rightarrow\frac{3 x}{4}-\frac{3 x}{4}=-12$

$\Rightarrow0 \times x=-12$

$\Rightarrowx=(\frac{-12}{0})=\infty$

So, there are infinite solutions to the system.

Find the eleventh term of the last term of A.P. 27,23,19,.....-65.

myrzilka [38]

The term to term rule is to subtract 4

Term 1 = 27
Term 2 = 27 - 4 = 23
Term 3 = 23 - 4 = 19
Term 4 = 19 - 4 = 15
Term 5 = 15 - 4 = 11
Term 6 = 11 - 4 = 9
Term 7 = 9 - 4 = 5
Term 8 = 5 - 4 = 1
Term 9 = 1 - 4 = -3
Term 10 = -3 - 4 = -7
Term 11 = -7 - 4 = -11

The eleventh term = -11

Can someone please help me solve for x? i already have y

Scrat [10]

Step-by-step explanation:

$\frac{3}{9} = \frac{5}{y} = \frac{x}{12} \\ \frac{3}{9} = \frac{5}{y} \\ 3y = 45 \\ y = 15 \\ \\ \frac{3}{9} = \frac{x}{12} \\ 9x = 36 \\ x = 4$
