Answer:

-1/6

Step-by-step explanation:


Solve one equation for one variable  v  then plug it into the other and solve for the other variable w .

5v+4w=1\\5v = 1-4w\\v = \frac{1-4w}{5}

Now plug v into the second equation:

\\3(\frac{1-4w}{5}) - 6w = 2\\3(\frac{1-4w}{5}) = 2+ 6w \\\frac{3-12w}{5} = 2+ 6w\\3-12w = 10+ 30w\\-42w = 7\\w = \frac{7}{-42} \\w =-\frac{1}{6}

Answer:

<h2>M(-6, 4)</h2>

Step-by-step explanation:

The formula of a midpoint of (x₁, y₁) and (x₂, y₂):

M\left(\dfrac{x_1+x_2}{2},\ \dfrac{y_1+y_2}{2}\right)

We have two points (-3, 7) and (-9, 1).

Substitute:

x=\dfrac{-3+(-9)}{2}=\dfrac{-12}{2}=-6\\\\y=\dfrac{7+1}{2}=\dfrac{8}{2}=4

Solve forx: x^2 = 5x
Akimi4 [234]

Answer:

x = 5

x = 0

Pulling out like terms :

2.1     Pull out like factors :

  x2 - 5x  =   x • (x - 5)

Equation at the end of step  2  :

 x • (x - 5)  = 0

Step  3  :

Theory - Roots of a product :

3.1    A product of several terms equals zero.

When a product of two or more terms equals zero, then at least one of the terms must be zero.

We shall now solve each term = 0 separately

In other words, we are going to solve as many equations as there are terms in the product

Any solution of term = 0 solves product = 0 as well.
