on a piece of paper, graph this system of equations. y = - x - 10 y = x^2 - 2x - 3 then determine which answer choice matches th

olasank [31]

Answer:

Option D. No solution

Step-by-step explanation:

<u>We have the equation of a line: </u>

$y = - x - 10$

We find their cut points.

<em>Cut point with the y axis. (x = 0) </em>

$y = -(0) -10\\y = -10$

<em>Cut point with the x axis. (y = 0) </em>

$0 = -x -10\\x = -10$ .

The line cuts to the x-axis at $x = -10$ and cuts the y-axis at $y = -10$

<u>We have a parabola </u>

$y = x ^ 2 - 2x - 3$

We can factor this quadratic equation by looking for 2 numbers that when multiplied give as result -3 and that when adding these numbers as a result -2. These numbers are -3 and 1.

Then the factors are:

$(x-3)(x + 1) = 0$

The zeros are 3 and -1. So <em>the parabola cuts to the x axis at points </em><em>3</em><em> and</em><em> -1</em><em>. </em>

<em>Now we find the cut points with the y axis. (x = 0) </em>

$y = (0-3)(0 + 1)\\y = -3.$

<em>The parabola cuts to the axis y in y = -3. </em>

Now we can graph the line and the parabola. Observe the attached image.

<em>The system has no solution because the line and the parabola never intersect or touch each other. The answer is the option D</em>

Find the missing part. use an improper fraction for your answer.

liubo4ka [24]

Answer:

$x = \frac{15}{2}$

Step-by-step explanation:

We have that $sin(\alpha) = \frac{side\ opositte}{hypotenuse}$

Then:

$sin(30) = \frac{x}{15}\\\\sin(30) = \frac{1}{2}\\\\\frac{1}{2} = \frac{x}{15}\\\\15(\frac{1}{2}) = x\\\\x = \frac{15}{2}$

Finaly, the answer is $\frac{15}{2}$
