Please help me thanks

9. The rate of change is 2/1 or just 2.

Step-by-step explanation:

Basically, X goes up by 1 every single time. Meanwhile Y goes up by 2 every time. So you put 2 on top, and 1 on the bottom and solve.

or just 2, after solving and getting rid of the 1

9. 2

10. -5

Step-by-step explanation:

9. The rate of change/slope can be determined by using the formula

In this problem, we can choose many different points. For the sake of simplicity, let's choose the first and last points. So is (0,-5) and is (4,3).

Plugging it in, we get:

10. The initial value of the graph is referring to the y-intercept. In this case, it would be -5.

Hope this helps!

a box 3 3/4 feet long or 4+ feet.

step-by-step explanation:

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
