Answer:
-1,3
Step-by-step explanation:
its -1,3 because when you do graph and put the lines they cross / touch like the orange and red are doing
Answer:
-7
Step-by-step explanation:
First, we need to substitute x in as 14 since that is what x is equal to.
1. x / y => 14 / y
Next, we need to substitute y in as -2 since that is what y is equal to.
2. 14 / y => 14 / -2
Now to solve it;
3. 14 / -2 => -7
So now we now that x / y equals -7 when x = 14 and y = -2.

Answer:
f(-2) = 5
Step-by-step explanation:
we are given with a function f(x) = - 4x – 3
we are asked to determine
f(-2)
in order to find f(-2) we will substitute x = -2 in our function f(x)
f(x)=-4x-3
f(-2) = -4(-2)-3
=8-3
=5
Hence f(-2) = 5
Answer:
20
Step-by-step explanation:
Use the distance formula to determine the distance between the two points.
![\text{Distance}=\sqrt{(x_2=x_1)^2+(y_2-y1)^2}](https://tex.z-dn.net/?f=%5Ctext%7BDistance%7D%3D%5Csqrt%7B%28x_2%3Dx_1%29%5E2%2B%28y_2-y1%29%5E2%7D)
Substitute the actual values of the points into the distance formula.
![\sqrt{((-7)-5)^2+((-7)-9)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%28%28-7%29-5%29%5E2%2B%28%28-7%29-9%29%5E2%7D)
Simplify.
⇒ Subtract 5 from 7.
![\sqrt{(-12)^2+((-7)-9)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%28-12%29%5E2%2B%28%28-7%29-9%29%5E2%7D)
⇒ Raise -12 to the power of 2.
![\sqrt{144+((-7)-9)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B144%2B%28%28-7%29-9%29%5E2%7D)
⇒ Subtract 9 from -7.
![\sqrt{144+(-16)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B144%2B%28-16%29%5E2%7D)
⇒ Raise -16 to the power of 2.
![\sqrt{144+256}](https://tex.z-dn.net/?f=%5Csqrt%7B144%2B256%7D)
⇒ Add 144 and 256.
![\sqrt{400}](https://tex.z-dn.net/?f=%5Csqrt%7B400%7D)
⇒ Rewrite 400 as 20².
![\sqrt{20^2}](https://tex.z-dn.net/?f=%5Csqrt%7B20%5E2%7D)
⇒ Pull terms out from under the radical, assuming positive real numbers.
