Answer:
The answer is x=-5
Step-by-step explanation:
In order to determine the equation, we need to know about vertical line equations.
In general, a line equation has the form:
Where "y" is the dependent variable, "x" is the independent variable, "m" is the slope of the line and "n" is the value where the line cuts the "y" axis.
A vertical line, x only takes one value. Thus, the equation for a vertical line is x = a, where a is the value that x takes.
So for the coordinate (-5,-1), the vertical line has to pass through the "x" value, that it is -5, therefore the equation of a vertical line passing through the point (-5,-1) is:
x=-5
Answer:

Step-by-step explanation:
Answer:
The area of the triangle is of 21 units of area.
Step-by-step explanation:
The area of a triangle with three vertices is given by the determinant of the following matrix:
In this question:
Vertices (1,0) (5,0) (3,4). So
The area of the triangle is of 8 units of area.
Answer:
4.3
Step-by-step explanation:
Apply trigonometric ratios to find the answer.
Firstly, we need to find the measure of angle theta. In order to do this, we will use triangle BAD.
From angle theta, the trigonometric ratio sine can be used:
sinθ =
After we find the value, we take the inverse sine of it and the result is approximately 50.7 degrees.
Now, knowing that angles BAD and CAD are the same, we can solve for CD using trigonometric ratio sine.
sin50.7 = opposite/hypotenuse
sin50.7 = CD/5.5
sin50.7 * 5.5 = CD
4.3 ≈ CD
Answer:
Step-by-step explanation:
They are equal. When the negative sign is inside the box the absolute value is positive, when the negative sign is outside the box THEN it is negative.
