What are the X intercept and the Y intercept of the graph of Y=-1/2x-5 and do your answers in the boxes x-intercept y-intercept
katrin [286]
X-intercept = (x,0)       y is zero
y- intercept = (0,y)      x is zero
In the equation y = -1/2 x -5
x-intercept would be 
0 = -1/2 x - 5
5 = -1/2x
x = -10 
y-intercept would be
y = -1/2 (0) - 5
y = -5

Thus, the answer is (-10,0) and (0,-5).

Please include an explanation.
Phantasy [73]

Answer:

y = 120 ( x - 1/2 ) ( x + 2 )

Step-by-step explanation:

As you can see in every parenthesis there is a coefficient in front of every x term. We do not want them do be there. So we ll eliminate them.

In other words we will factor out from inside each parenthesis the coefficient. So:

y =  - 3(4 - 8x)(5x + 10) \\ y =   + 3( - 4 + 8x)(5x + 10) \\ y = 3(8 x - 4)(5x + 10) \\  \\ y = 3(8(x -  \frac{1}{2} ))(5(x + 2)) \\ y = 3 \times 8 \times (x -  \frac{1}{2} ) \times 5 \times (x + 2) \\ y = (3 \times 8 \times 5)(x -  \frac{1}{2} )(x + 2) \\ y = 120(x -  \frac{1}{2} )(x + 2)

A flagpole casts a 13-foot shadow on the ground when the sun is at a 68° angle of elevation.
Ymorist [56]

Step-by-step explanation:

<u>Step 1:  List out all of the formulas for the trigonometric functions </u>

<em>sin(x) </em>= opposite/hypotenuse

<em>cos(x) </em>= adjacent/hypotenuse

<em>tan(x)</em> = opposite/adjacent

<u>Step 2:  Find the value of h </u>

cos(68) = 13/unknown is FALSE

cot(68) = 13/h is FALSE

sin(68) = h/unknown is FALSE

tan(68) = h/13 is TRUE

Answer: The correct option would be D
