Determine which method works, substitution or elimination? 4x^2+3y^2=42x^2-6y^2=-3

GarryVolchara [31]

Given:

$\begin{gathered} 4x^2+3y^2=4 \\ \\ 2x^2-6y^2=-3 \end{gathered}$

Find the method .

Sol:

$\begin{gathered} 4x^2+3y^2=4..............(1) \\ \\ 2x^2-6y^2=-3.............(2) \end{gathered}$

2eq(1) + eq(2) then,

$8x^2+6y^2=8$

Then apply the elimination method.

$\begin{gathered} 8x^2+6y^2=8 \\ 2x^2-6y^2=-3 \\ --------- \\ 10x^2=5 \\ \\ x^2=\frac{5}{10} \\ \\ x=\sqrt{\frac{1}{2}} \end{gathered}$

Is the following true for all positive values of a and b: If a^2>b^2, then a>b

Dominik [7]

Answer:

Yes, that is correct.

Step-by-step explanation:

a would always have to be greater than b since you're just multiplying each variable by itself.

-5x + 12 - 7x = -3(5x + 8)

nikitadnepr [17]

Simplify -5x + 12 - 7x to -12x + 12

-12x + 12 = -3(5x + 8)

Expand

-12x + 12 = -15x - 24

Add 15x to both sides

-12x + 12 + 15x = -24

Simplify 12x + 12 + 15x to 3x + 12

3x + 12 = -24

Subtract 12 from both sides

3x = -24 - 12

Simplify -24 - 12 to -36

3x = -36

Divide both sides by 3

x = -36/3

Simplify 36/3 to 12

Help me please i don’t understand

LenaWriter [7]

Answer:

Step-by-step explanation:

There are 10 red candies, 18 green candies, 9 yellow candies, and 13 brown candies.

10 + 18 + 9 + 13 = 50.

There is a total of 50 candies. Out of the 50 candies, 18 are green.

$\frac{18}{50} \\$

You have to get to 250 .That means you do $\frac{18}{50} = \frac{x}{250}$

250 divided by 50 = 5.

18 x 5 = 90.

Therefore, she can expect 90 green candies
