Graph the points. Then conect them. From on point count up or down to where it's in line with the other point. Then count across so you touch the other point. So maybe you got -8/4? Remember to reduce to -2
Let's call this blank X
x÷4=9
x=4×9
x=36
hope that helped
d = kv
Substitute the 60 and 120 in.
120 = k * 60
k = 2
So, d = 2v
If v is 65, what is d?
2 * 65 = 130 miles
Answer:
![\Large \boxed{x\geq -\frac{1}{2}}](https://tex.z-dn.net/?f=%5CLarge%20%5Cboxed%7Bx%5Cgeq%20-%5Cfrac%7B1%7D%7B2%7D%7D)
Step-by-step explanation:
The domain is all possible values for x.
![y=4\sqrt{4x+2}](https://tex.z-dn.net/?f=y%3D4%5Csqrt%7B4x%2B2%7D)
There are restrictions on the value of x.
A square root of a negative number is undefined.
The number in the square root has to be equal to 0 or be greater than 0.
![4x+2\geq 0](https://tex.z-dn.net/?f=4x%2B2%5Cgeq%200)
Subtract 2 from both sides.
![4x\geq -2](https://tex.z-dn.net/?f=4x%5Cgeq%20-2)
Divide both sides by 4.
![\displaystyle x\geq -\frac{2}{4}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20x%5Cgeq%20-%5Cfrac%7B2%7D%7B4%7D)
