Simplify the expression.

mr Goodwill [35]

Answer:

$x^{\frac{1}{2}}$

Step-by-step explanation:

we have

$(x^{\frac{1}{6}})^{3}$

Applying the rule power

$(b^{n})^{m}=b^{n*m}$

$(x^{\frac{1}{6}})^{3}=(x^{\frac{1}{6}*3})=x^{\frac{3}{6}}$

Simplify

$x^{\frac{1}{2}}$

Which statement correctly compares the two functions shown?

krok68 [10]

Answer:

Step-by-step explanation:

For Function 2

x=1 y=8

x=2 y=11

8=m+b

11=2m+b

11-8=2m-m

m=3

8=3+b

b=5

y=3x+5

Function 1

y=4x+5

Function 2

y=3x+5

....................

Function 1 has the same y-intercept and greater slope than Function 2.

Can someone help please?

Katarina [22]

Answer:

g = 6

Step-by-step explanation:

To find the slope you do:

m = change in y ÷ change in x or (y2 - y1) ÷ (x2 - x1)

x1 = 4, y1 = -7
x2 = g, y2 = -3
m (the slope) = 2

Sub in the values:

2 = (-3 - -7) ÷ (g - 4) - we can simplify this

2 = (4) ÷ (g - 4)

4 divided by what gives us 2? 2. This means that g - 4 = 2, g = 2 + 4 which is 6:

g = 6

Hope this helps!
