1 answer:

3 0

Distributeiv poepty
a(b+c)=ab+ac

remember that (-) times (-)=(+)
and (+) TIMES (-)=(-)

SO
-7(-5v-3u+4)=(-7)(-5v)+(-7)(-3u)+(-7)(4)=35v+21u-28

Given the following system of equations: -4x+8=16, 2x+4y=32 what action was completed to create this new equivalent system of eq

castortr0y [4]

The equation (1) is divided by 2 to create new equivalent system of equations.

Step-by-step explanation:

The given systems of equations are:

$-4x+8y=16\,\,\,(1)\\2x+4y=32\,\,\,(2)$

Considering 8y instead of 8 in eq(1)

We need to identify what action was completed to create this new equivalent system of equations? $-2x+4y=8, 2x+4y=32$

Comparing given equations we came to know that equation(1) is divided by 2 to get the new equation i.e

$-4x+8y=16\\Divide\,\,by\,\,2:\\-2x+4y=8$

While second equation is same as given.

So, The equation (1) is divided by 2 to create new equivalent system of equations.

Who would you go about this.

Nostrana [21]

A. First move all to the left side of the equation(Normal form)

x^3 - 49x= 0

B. Factor out an x, which is the GCF (Factored form)

x(x^2 - 49) = 0

C. Find solutions by making each x piece equal to 0. The first part is just x=0 and the second part is just factoring the difference of squares and then solving.

x=0, x^2 - 49 =0

x=0, x + 7 = 0, x - 7 = 0

Therefore, the answers for Part C are:
x = 0, x = -7, x = 7
