-5x-4y=10
strojnjashka [21]

Answer:

y intercept = (0, ~-\frac{5}{2} )

x intercept = (-2, ~0)

.

Step-by-step explanation:

-5x - 5y = 10

.

y intercept

\to x = 0

-5(0) - 4y = 10

-4y = 10

y = \frac{10}{-4}

y = -\frac{5}{2}

so, the answer is (0, ~-\frac{5}{2} )

.

x intercept

\to y = 0

-5x - 4(0) = 10

-5x = 10

x = \frac{10}{-5}

x = -2

so, the answer is (-2, ~0)

.

Happy to help :)

(50 POINTS) What is the length of YZ in Triangle XYZ? Explain two different methods that could be used to find this length.
LenKa [72]
<h3>First Method:</h3>

<u>Using cosine rule</u>:

\rightarrow \sf cos(30 ) = \dfrac{YZ}{12}

\rightarrow \sf YZ = 12cos(30 )

\rightarrow \sf YZ = 6\sqrt{3}

\rightarrow \sf YZ = 10.4

<h3>Second Method:</h3>

<u>First find XY using sine rule</u>:

\rightarrow \sf sin(30)=\dfrac{XY}{12}

\rightarrow \sf XY = 12sin(30)

\rightarrow \sf XY =6

Then use Pythagoras Theorem:

⇒ XY² + YZ² = XZ²

⇒ (6)² + YZ² = 12²

⇒ YZ² = 144 - 36

⇒ YZ = √108

⇒ YZ = 6√3

⇒ YZ = 10.4

How to graph y = 2|x + 3| - 4
mr_godi [17]

The x-intercepts and the y-intercepts of the function is that determines the graph is:

  • x-intercepts = (-5,0) and (-1,0)
  • y-intercepts = (0,2)

<h3>How do we graph the function y = f(x) of an absolute equation?</h3>

The function of an absolute equation can be graphed by determining the values of x-intercepts and the y-intercepts of the function.

From the given equation:

y = 2|x+3| - 4

To determine the y-intercepts, we need to set the values of x to zero, and vice versa for x-intercepts.

By doing so, the x-intercepts and the y-intercepts of the function is:

  • x-intercepts = (-5,0) and (-1,0)
  • y-intercepts = (0,2)

Therefore, since we know the x and y-intercepts, the graph of the absolute value can be seen as plotted below.

snow_lady [41]

Answer:

Is C. Never

Step-by-step explanation:

In three-dimensional geometry, skew lines are two lines that do not intersect and are not parallel. A simple example of a pair of skew lines is the pair of lines through opposite edges of a regular tetrahedron.
