\bf 8x^3-10x^2+3x=0\implies x(8x^2-10x+3)=0
\\\\\\
x(2x-1)(4x-3)=0\implies 
\begin{cases}
x=0\implies &x=0\\\\
2x-1=0\implies 2x=1\implies &x=\frac{1}{2}\\\\
4x-3=0\implies 4x=3\implies &x=\frac{3}{4}
\end{cases}

Answer:

Infinite solutions

Step-by-step explanation:

Given is a system of equations.

-3x+y=10

-6x+2y=20

Equation I when multiplied by 2, gives as

-6x+2y =20 which is the same as equation 2 given.

This gives the two lines are not intersecting nor parallel.  But the two lines are coincident with each other.

Hence each point on the line is solution.

Infinite solutions.

Let us try to solve and verify this

BY substitutition we have y = 3x+10, substitute in II

-6x+2(3x+10) =20

Or -6x+6x+20=20

20=20 Thus for any x, this becomes true.

Hence infinite solutions.

Can Some one please help me on these math questions<br><br>I'll give 20 points please
MArishka [77]

Answer:

☐ -2 < 2x + 4

☐ -3x - 2 > 5

Step-by-step explanation:

-3x - 2 > 5

+ 2 + 2

___________

-3x > 7

___ ___

-3 -3

x < -2⅓ [Anytime you <em>divide</em> or <em>multiply</em> by a negative, reverse the inequality symbol.]

-2 < 2x + 4

-4 - 4

___________

-6 < 2x

__ ___

2 2

-3 < x

If you plug in -3 for <em>x < -2</em><em>⅓</em><em>,</em><em> </em>you will see that it is a genuine statement because the more higher a negative gets, the lesser the integer will be, so in this case, -3 IS <em>less</em><em> </em><em>than</em><em> </em>-2⅓.

I am joyous to assist you anytime.

** If it is not multi-select, then choose <em>-2 < 2x + </em><em>4</em><em>.</em>
