Answer:

(x, y) = (-7, 7)

Step-by-step explanation:

y= 7

-3 - 2x = 7

Substitute the given value of y into the equation

- 3x - 2 x 7 = 7

Solve for the equation for x

x = -7

The possible solution of the system is the ordered pair (x, y)

(x, y) = ( -7, 7)

Check if the given ordered pair is the solution of the system of equations

7= -3x (-7) - 2 x 7 = 7

= 7 = 7 = 7

Answer:

x = -3

(-3,7)

Step-by-step explanation:

y = –3x – 2,

y = 7

We know the value of y, y=7

Substitute into the first equation

7 = –3x – 2

Add 2 to each side

7+2 = –3x – 2+2

9 = -3x

Divide each side by -3

9/-3 = -3x/-3

-3 = x

Complete Question

The following is a set of hypotheses, some information from one or more samples, and a standard error from a randomization distribution. Test $H_o : p = 0.28$ vs $H a : p < 0.28$ when the sample has n 900 , and $\^ p = 0.216$ with $SE= 0.01$ . Find the value of the standardized z -test statistic. Round your answer to two decimal places.
