What are the solution(s) to the quadratic equation 9x2 = 4?x =4/9 and x = -4/9
x = 2/3 and x = -2/3
x = 3/2 and x = -3/2
no real solution

Answers

Answer 1

Answer:

we have

$9x^(2)=4$

Divide both sides by $9$

$9x^(2)/9=4/9$

$x^(2)=4/9$

Square root both sides

$x=(+/-)\sqrt{(4)/(9)}$

$x=(+/-)(2)/(3)$

the solutions are

$x1=(2)/(3)$

$x2=-(2)/(3)$

therefore

the answer is the option

x = 2/3 and x = -2/3

Answer 2

Answer:

The solutions to the quadratic equation; 9x2 = 4 are; x = 2/3 and x = -2/3.

Quadratic solutions

The given quadratic equation is;

9x² = 4.

Hence, upon evaluation; we have;

x² = 4/9

Hence, x = ±2/3

Therefore, x = 2/3 and x = -2/3

suize can run 2.5mile per hr faster then jeff. in the time it takes suize to run 6 mile jeff runs 4 mile find the speed of each runner

Answers

If you would like to know the speed of each runner, you can calculate this using the following steps:

6 miles ... x + 2.5 mile per hr (Suize)
4 miles ... x mile per hr (Jeff)

6 * x = 4 * (x + 2.5)
6 * x = 4 * x + 4 * 2.5
2 * x = 4 * 2.5
2 * x = 10
Jeff: x = 5 mile per hr

Suize: x + 2.5 = 5 + 2.5 = 7.5 mile per hr

Suize runs 7.5 mile per hr, and Jeff 5 mile per hr.
