The smallest side of a 30-60-90
Aleonysh [2.5K]

Answer: A 30-60-90 triangle is a special right triangle (a right triangle being any triangle that contains a 90 degree angle) that always has degree angles of 30 degrees, 60 degrees, and 90 degrees. Because it is a special triangle, it also has side length values which are always in a consistent relationship with one another.

The basic 30-60-90 triangle ratio is:

Side opposite the 30° angle: x

Side opposite the 60° angle: x*√3

Side opposite the 90° angle: 2x

Graph the line of the equation x4+y=−2 using its slope and y-intercept
k0ka [10]

Answer:

y-intercept = c = -2

slope = y = - 4

Step-by-step explanation:

The correct equation is:

4x + y =  -2

We need to graph the line using its slope and y-intercept. The slope intercept form of the equation is:

y = mx + c

Here, m is the slope and c is the y-intercept. Transforming the given equation to this form gives us:

y = - 4x - 2

This means, the slope is:

m = - 4

and y-intercept is:

c = - 2

y-intercept in ordered pair is written as (0, c). So for the given case the y intercept will be (0, -2). This gives us first point on the graph.

The slope tells us that by how many units will the y variable will change for one unit change in x-axis.

So slope, m = - 4, tells us that the y-variable will change by negative 4 units for 1 unit change in x variable.

Based on this change, we can get another point from (0, -2) which will be (0+1, -2 - 4) = (1, - 6)

This gives us the second point on the graph. Plot these two points and join them using a straight line. This straight line will be the graph of equation y = 4x - 2 or 4x + y = -2

The graph is attached below.

What is the slope of the line through (3, 2) and (-3,4)?​
Andre45 [30]

Answer:

Choice A. -3

Step-by-step explanation:

Using the x1-x2/ y1-y2 u fill in. So it would be 3-(-3) (x-axis) and 2-4 (y-axis).

So when u do both of those you are left with 6/-2.

When u simplify 6/-2 you get -3.

Y=1/2x-3,y=x-5<br>I've been trying for hours pls help me with the elimination method​
Ilia_Sergeevich [38]

The solution is x = 4 and y = -1

Step-by-step explanation:

The system of equation is:

  • y = \frac{1}{2} x - 3
  • y = x - 5

To solve it using the elimination method do that

∵ y = \frac{1}{2} x - 3 ⇒ (1)

∵ y = x - 5 ⇒ (2)

- Subtract equation (1) from equation (2) to eliminate y

∵ y - y = (x - \frac{1}{2} x) - 5 - (-3)

- Remember (-)(-) = (+)

∴ 0 = \frac{1}{2} x - 5 + 3

∴ 0 = \frac{1}{2} x - 2

- Add 2 to both sides

∴ 2 = \frac{1}{2} x

- Multiply both sides by 2

∴ 4 = x

∴ x = 4

- Substitute the value of x in equation (1) or (2) to find y

∵ y = 4 - 5

∴ y = -1

The solution is x = 4 and y = -1
