this is simple

since y = -1

y = 5x + 4

-1 = 5x + 4

5x = -5

x = -1

therefore answer is (-1, -1)

Answer:

Step-by-step explanation:

since it tells you y is=1 plug that into the top equation

-1=5x+4

-1=x

and you already have y=-1

so its(-1,-1)

Point P(5,0) is on the terminal arm of an angle k in standard position.

7nadin3 [17]

The value of the cosine of angle $k$ is 1.

Given a point $(x,y)$ that is a terminal arm of an angle $k$ in standard position, by trigonometric relations we have the following expression for the cosine:

$\cos k = \frac{x}{\sqrt{x^{2}+y^{2}}}$ (1)

Where:

$k$ - Angle measure, in sexagesimal degrees.
$x$ - Horizontal position of the point of the terminal arm, no unit.
$y$ - Vertical position of the point of the terminal arm, no unit.

If we know that $x = 5$ and $y = 0$ , then the cosine of the angle $k$ is:

$\cos k = \frac{5}{\sqrt{5^{2}+0^{2}}}$

$\cos k = 1$

The value of the cosine of angle $k$ is 1.
