Answer:
Step-by-step explanation:
it's important to mention this only works for right triangles. Or in other words a triangle that has a 90 degree angle. the two sides connected to that right angle are called legs, while the one side not touching it is the hypotenuse, which is what we're looking for.
we are going to use the Pythagorean theorem. if we label one leg a and the other as b, it doesn't matter which one is which, and the hypotenuse as c we have the relation
so let's plug in.
let me know if you need any more help.
Answer:
n = -14
Step-by-step explanation:
Let us try to solve this equation for n;
3x + 1 - 9 = 3(x + 2) + n
3x - 8 = 3x + 6 + n
3x - 3x -8 - 6 = n
-14 = n
The value of n = -14
This value is the value of the equation that will have no solution.
To know if we are correct, let us input this value into the expression
3x + 1 - 9 = 3(x + 2) + n
3x - 8 = 3x + 6 -14
Collect like terms;
3x - 3x = 8 + 6 - 14
0 = 0
Answer:
its line a

Answer:
Step-by-step explanation:
7x + 3 = 9x - 19
-2x + 3 = -19
-2x = -22
x = 11
DE= 7(11) + 3 = 77 + 3 = 80
EF = 9(11) - 19 = 99 - 19 = 80
80 + 80 = 160 for DF
Answer:
(x, y) = (0, p)
Step-by-step explanation:
In the given equation, p is the distance from the vertex (0, 0) to the focus of the parabola. Any vertical "light beam" will bounce off the curve and pass through the focus at (0, p).
