Answer:

  (x, y) = (-1, -2)

Step-by-step explanation:

I like a graphing calculator for solving systems of equations. It shows the point of intersection is (-1, -2).

__

You can add 4 times the second equation to the first:

  (2x -4y) +4(3x +y) = (6) +4(-5)

  14x = -14 . . . . simplify

  x = -1 . . . . . . . divide by 14

Now, you can put this value in the second equation to get ...

  3(-1) +y = -5

  y = -2 . . . . . . . add 3

The point of intersection is (x, y) = (-1, -2).

Determine the value of the ?

Answer:

x^{2} y^{3}

Step-by-step explanation:

Using the Quotient rule:

\frac{a^{m}}{a^{n}} = a^{m - n}

We can subtract the exponents of x and y:

\frac{x^{6} y^{10}}{x^{4} y^{7}} = x^{(6 - 4)} y^{(10 - 7)}

Therefore, \frac{x^{6} y^{10}}{x^{4} y^{7}} = x^{2} y^{3}

Surveys conducted in American high schools concluded that 90% of the students in a sample of 400 students had more than one acti
kenny6666 [7]
The sample proportion has an approximately normal distribution, with the mean being the population mean and the standard deviation (i.e. the standard error of the sampling proportion) equal to 

SE = sqrt(p*q/n) where p is the population proportion q is 1-p, and n is the sample size. 

<span>(Typically, for a confkdence interval, the sample proportion and its complement are substituted for p and q.) </span>

The margin of error will be Zc*SE, where Zc is the critical value of Z for the level of confidence required. The confidence interval, then, will be the sample proportion, plus or minus the margin of error. 

For a 90% confidence interval, Zc is 1.645. 

<span>So the margin of error is 1.645 * sqrt(.9*.1/400), roughly .025. So your confidence interval would be around [.875, .925] 


The best and most correct answer among the choices provided by your question is the second choice or letter C which is 3%.
I hope my answer has come to your help. Thank you for posting your question here in Brainly.</span>

F(x)=x^2 what is g(x)
Triss [41]

Answer: D

Step-by-step explanation:

Sometimes, it is hard to see which function fits g(x). We are given the point (4,1). Luckily, the point lies on g(x). We can plug in (4,1) into the g(x) equations and see which best fits.

A. Incorrect

1=4(4)^2

1=4(16)

1\neq 64

B. Incorrect

1=\frac{1}{4} (4)^2

1=\frac{1}{4} (16)

1\neq 4

C. Incorrect

1=(\frac{1}{2}(4))^2

1=(2)^2

1\neq 4

D. Correct

1=(\frac{1}{4}(4))^2

1=(1)^2

1=1
