Please help me, I'm doing a test.
Tju [1.3M]

Answer:

(3,4)

Step-by-step explanation:

first you're going to solve the equation -2x

your equation should now be: \left \{ {{-2x+3y\\=6} \atop {-2x=2-2y}} \right.

next you're going to substitute the given value of -2x into the equation -2x+3y=6

so your equation should now be: 2-2y+3y=6

next you're going to solve the equation for y

equation should now be: y=4

than you're going to substitute the given value of y into the equation -2x=2-2×4

then you're going to solve the equation for x

your equation should now be: x=3

then the possible solution of the system is the order pair: (x,y)=(3,4)

\bf \cfrac{3}{x-2}+\cfrac{4}{x-1}-\cfrac{1}{x}    so, no breaks on the denominator thus, the LCD will be all three then.

\bf \cfrac{3}{x-2}+\cfrac{4}{x-1}-\cfrac{1}{x}\implies \cfrac{[3x(x-1)]+[4x(x-2)]-[(x-2)(x-1)]}{x(x-2)(x-1)}&#10;\\\\\\&#10;\cfrac{[3x^2-3x]+[4x^2-8x]-[x^2-3x+2]}{x(x-2)(x-1)}&#10;\\\\\\&#10;\cfrac{3x^2-3x+4x^2-8x-x^2+3x-2}{x(x-2)(x-1)}&#10;\\\\\\&#10;\cfrac{6x^2-8x-2}{x(x-2)(x-1)}\implies \cfrac{2(x^2-4x-1)}{x(x-2)(x-1)}

The linear combination method is applied to a system of equations as shown.
tensa zangetsu [6.8K]

Answer:

(9,3)

Step-by-step explanation:

4(.25x + .5y = 3.75) → x + 2y = 15

(4x – 8y = 12) → x – 2y = 3

2x = 18

Divide both sides by 2

x = 9

Substitute x = 9 into  x + 2y = 15

9 + 2y = 15

Subtract 9 from both sides

2y = 6

Divide both sides by 2

y = 3

Solution

(9, 3)

Tell whether the lines through the given points are parallel, perpendicular, or neither?
Paha777 [63]

Slope\,\,1=\frac{-1}{slope\,\,2}

So, Both lines are perpendicular

Step-by-step explanation:

We need to identify if lines:

Line 1: (8,12)(7,-5)

Line 2: (-9,3)(8,2)

are parallel, perpendicular, or neither?

  • Lines are parallel if they have same slopes i.e slope 1= slope2
  • Lines are perpendicular if their slopes are negative inverses of each other i.e slope 1= -1/slope 2

The formula used to find slope is:

Slope=\frac{y_2-y_1}{x_2-x_1}

Finding Slope of Line 1:

The points are: Line 1: (8,12)(7,-5)

x_1=8, y_1=12, x_2=7,y_2=-5

Putting values in the formula:

Slope\,\,1=\frac{y_2-y_1}{x_2-x_1}

Slope\,\,1=\frac{-5-(12)}{7-8}

Slope\,\,1=\frac{-5-12}{-1}

Slope\,\,1=\frac{-17}{-1}

Slope\,\,1=17

So, Slope of line 1 is 17

Finding Slope of Line 2:

The points are: Line 2: (-9,3)(8,2)

x_1=-9, y_1=3, x_2=8,y_2=2

Putting values in the formula:

Slope\,\,2=\frac{y_2-y_1}{x_2-x_1}

Slope\,\,2=\frac{2-(3)}{8-(-9)}

Slope\,\,2=\frac{2-3}{8+9}

Slope\,\,2=\frac{-1}{17}

So, Slope of line 2 is \frac{-1}{17}

Since Slope\,\,1=\frac{-1}{slope\,\,2}

So, Both lines are perpendicular
