Try substituting those values, and you will see they do not fit either equation.

looking at the 2nd equation, y = x+2, so

x+2 = x^2+5x-3

x^2 + 4x - 5 = 0

(x+5)(x-1) = 0

x = -5 or 1

so, y = -3 or 3

the solutions are thus (-5,-3)(1,3)

Hope this helps

Answer-

(-5,-3)(1,3)

How I got my answer-

×+2=×^2+5×-3

×^2+4×-5=0

(×+5)(×-1)=0

×= -5 or 1

and y=3 or 3

Answer:

$0.625 \pm 1.645*0.0571$

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of $\pi$ , and a confidence level of $1-\alpha$ , we have the following confidence interval of proportions.

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which

$\pi$ is the estimate

z is the zscore that has a pvalue of $1 - \frac{\alpha}{2}$ , also called the critical value.

The standard error is:

$s = \sqrt{\frac{\pi(1-\pi)}{n}}$

90% confidence level critical value

So $\alpha = 0.1$ , z is the value of Z that has a pvalue of $1 - \frac{0.1}{2} = 0.955$ , so $z = 1.645$ .

Estimate:

72 petty theft cases and finds 45 of these have gone unsolved.

So $\pi = \frac{45}{72} = 0.625$

Standard error:

$s = \sqrt{\frac{\pi(1-\pi)}{n}} = \sqrt{\frac{0.625*0.375}{72}} = 0.0571$

Answer:

$0.625 \pm 1.645*0.0571$
