use the substitution method to solve the system of equations. Choose the correct ordered pair. y=4x 8x+y=18

tino4ka555 [31]

Answer:

(3/2, 6)

Step-by-step explanation:

y = 4x

8x + y = 18

this says y is 4x so you can replace y with 4x

8x + 4x = 18

12x = 18

/12 /12

x = 3/2

now sub x into y = 4(3/2)

y = 12/2

y = 6

What are the solution(s) to the quadratic equation 9x2 = 4?

Kaylis [27]

Answer:

Option B.

Step-by-step explanation:

The given quadratic equation is

$9x^2=4$

We need to find the solution of given quadratic equation.

Divide both sides by 9.

$\frac{9x^2}{9}=\frac{4}{9}$

$x^2=\frac{4}{9}$

Taking square root on both sides.

$x=\pm\sqrt{\frac{4}{9}}$

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

The solution of given equation are $x=\frac{2}{3}$ and $x=-\frac{2}{3}$ .

Therefore, the correct option is B.
