PLEASE HELP AS SOON AS POSSIBLE THANK YOU!!

Answer:

We know that when x= -10, y= -17.

So, if we put those into direct variation "y=kx", we get

-17= k(-10)

k = -17 / -10

Now we put the value of "k" into the formula and we get A (y= 17/10x )

I need help with geometry

astra-53 [7]

Answer:

Step-by-step explanation:

Use the Pythagorean theorem:

a^2 + b^2 = c^2
5^2 + 12^2 = c^2
25 + 144 = c^2
c^2 = 169

Note: This also happens to be a Pythagorean triple where all three numbers are integers. These can be memorized.

What is the domain of the function y = -4x+1 if the range is -11

a_sh-v [17]

The range of a function is the set of all values that it can take when its independent variable takes values on the domain.

On the other hand, the range of a function is the domain of its inverse function, if that inverse exists, and vice-versa: the domain of a function is the range of its inverse function, if that inverse exists.

In the case of the given equation:

$y=-4x+1$

The inverse function exists since the function is linear, and it can be found by isolating <em>x</em>:

$x=-\frac{1}{4}(y-1)$

If the range of the original function is the set given by the number {
