Answer:
A. (-10,18); 412 yards
Step-by-step explanation:
Answer:
<em>50 sq. units </em>
Step-by-step explanation:
The length of the base and the height of a triangle are numerically equal.
Let us assume that, the length and height as x.
So the area of the triangle will be,
As their sum is 30 less than the number of units in the area of the triangle, so
Neglecting negative roots,
Hence, the base and height of the triangle is 10 units, so the area will be,
The information from the first equation gives you the information needed for the second. To solve the first equation you must rearrange the equation to isolate X. In order to do that you can first move the 3 to the other side of the equation by subtracting it from both sides (5x + 3 - 3 = 4 - 3) and then simplify that to (5x = 4 - 3) and further to (5x = 1). Then to move the 5 you must divide both sides by 5 so you get (5x/5 = 1/5) which can be simplified to (x = 1/5)
From this you can use the X value and input it into the second equation
Y = -3(1/5) and then solve for Y.
Hope this helps!
When reflected across the y axis, the x coordinate becomes the opposite but the y coordinate stays the same, so N is (2, -5)
