Answer:

65 degrees

Step-by-step explanation:

If the angle at the top there is 35 degrees, then the angle directly underneath is also 35 degrees, and the angle of 80 degrees is given, and 80+35=115, and the sum of the angles in a triangle is 180, and so 180-115=65. 65 degrees=x

verbally explain how to obtain the graph of the quadratic function f(x)=-2(x+3)^2-4 from the graph of y=x^2.

Ksivusya [100]

Answer:

The graph f(x)= $-2(x+3)^2-4$ is a reflection over the x-axis, vertical stretch by a factor of 2, a horizontal translation left 3 units and a vertical translation 4 units down of the graph y= $x^2$ .

Step-by-step explanation:

The graph f(x) is reflected over the x-axis because the negative is outside of the parenthesis.

it's a vertical stretch by a factor of 2 because 2 is outside of the parenthesis and is greater than 1.

(x+3) is a horizontal translation left 3 units because it is inside the parenthesis.

-4 is vertical translation 4 units down because it is outside of the parenthesis.

15 - x = 2x + 6
15 = 3x + 6
9 = 3x
3 = x
