What is the value of x enter your answer in the box
OverLord2011 [107]

Answer:

x = 55°

Step-by-step explanation:

The sum of the 3 angles in a triangle is 180°

Subtract the sum of the 2 given angles from 180 for x

x = 180° - (75 + 50)° = 180° - 125° = 55°

Rewrite the following quadratic functions in intercept or factored form. Show your work.
Mariulka [41]

<u>Answer:</u>

y = 5x (x+2)

<u>Step-by-step explanation:</u>

We are given the following the quadratic function and we are to rewrite it in intercept or factored form:

y = 5x^2 + 10x

We can factorize the given expression so taking the common factors out of it to get:

y=5x^2 + 10x

y = 5x (x + 2)

Therefore, the factored form of the given quadratic function is y = 5x (x+2).

Answer:

  • quadratic function
  • y-intercept:  y = -6
  • x-intercepts:  x = 2 and x = 6
  • y = 2, x = 4
  • y ≥ 0

Step-by-step explanation:

The given graph is a <u>parabola</u> and so it a quadratic function.

The y-intercept is the point at which the curve <u>crosses the y-axis</u>.

From inspection of the graph, this is when y = -6.

The x-intercepts are the points at which the curve <u>crosses the x-axis</u>.

From inspection of the graph, the x-intercepts are x = 2 and x = 6.

The vertex is the <u>turning point</u> of the graph, so the <u>minimum point</u> of a parabola that opens <u>upwards</u>, and the <u>maximum</u> point of a parabola that opens <u>downwards</u>.

From inspection of the graph, the vertex is at (4, 2), so the greatest value of y is y = 2, and it occurs when x = 4.

The curve is <u>above the x-axis</u> between the interval x = 2 and x = 6.

Therefore, the function value is equal to zero or <u>positive</u> in this interval.

So the function value in the given interval is y ≥ 0.
