Solve using your choice of graphing, substitution, or elimination

antiseptic1488 [7]

Answer:

x = 110, y = 153.

Step-by-step explanation:

4x - 3y = -19 Multiply by 2

3x - 2y= 24 Multiply by 3.

8x - 6y = -38

9x - 6y = 72 SUBTRACT

-x = - 110

x = 110

Substitute for x :

3(110) - 2y = 24

2y =330 - 24

2y = 306

y = 153.

What are the solutions of 3(x – 4)(2x - 3) = 0? Check all that apply.

dangina [55]

Answer:

The solution to the equation is:

$x=4,\:x=\frac{3}{2}$

Step-by-step explanation:

Given the equation

$3\left(x-4\right)\left(2x-3\right)=0$

Using the zero factor principle

if ab=0, then a=0 or b=0 (or both a=0 and b=0)

$x-4=0\quad \mathrm{or}\quad \:2x-3=0$

now solving

$x - 4 = 0$

adding 4 to both sides

$x - 4 + 4 = 0 + 4$

simplifying

$x = 4$

and also solving

$2x - 3 = 0$

adding 3 to both sides

$2x - 3 + 3 = 0 + 3$

simplifying

$2x = 3$

divide both sides by 2

$\frac{2x}{2}=\frac{3}{2}$

simplifying

$x=\frac{3}{2}$

Therefore, the solution to the equation is:

$x=4,\:x=\frac{3}{2}$

$\bf ~\hspace{7em}\textit{negative exponents} \\\\ a^{-n} \implies \cfrac{1}{a^n} ~\hspace{4.5em} a^n\implies \cfrac{1}{a^{-n}} ~\hspace{4.5em} \cfrac{a^n}{a^m}\implies a^na^{-m}\implies a^{n-m} \\\\[-0.35em] ~\dotfill$

$\bf \cfrac{4(3x^2y^4)^3}{(2x^3y^5)^4}\implies \cfrac{4(3^3x^{2\cdot 3}y^{4\cdot 3})}{(2^4x^{3\cdot 4}y^{5\cdot 4})}\implies \cfrac{4(27)x^6y^{12}}{16x^{12}y^{20}}\implies \cfrac{108x^6y^{12}}{16x^{12}y^{20}} \\\\\\ \cfrac{108}{16x^{12}x^{-6}y^{20}y^{-12}}\implies \cfrac{108}{16x^{12-6}y^{20-12}}\implies \cfrac{27}{4x^6 y^8}$
