If an x intercept only touches the x axis it means it has a multiplicity of 2. If an intercept goes through the axis it has a mu
Dima020 [189]

If the multiplicity is even, the x-intercept will touch the x-axis and turn away (sometimes people call this "kissing" the x-axis). If the multiplicity is odd, the intercept will go right through the x-axis, so the answer to your question is false. In general, remember that odd crosses and even touches/turns/kisses.

Write an inequality, in slope-intercept form, for the graph below. If necessary,
d1i1m1o1n [39]

Answer:not 100 % sure but I can write a slope intercept form equation, but not an inequality. I would need a picture of the graph to write an inequality.

First find slope: (y2 - y1)/(x2 - x1)   Slope is 3

Choose a point then use point slope form y - y1 = m(x - x1)      It is y - 1 = 3(x - 1)

Now simplify:

y - 1 = 3(x - 1)

y - 1 = 3x - 3

y = 3x - 2

y = 3x - 2

Answer:

\frac{81}{m^7}

Step-by-step explanation:

We have a certain expression and are asked to find its equivalent with the answers provided :

(3m^{-4} )^3(3m^5)

Remove the parenthesis around 3m^5 :

(3m^{-4} )^3*3m^5

Do the exponent rule for outside and inside exponent parenthesis :

(3m^{-4*3} )

3^3m^{-12} *3m^5

Apply addition exponent rule :

m^{-12} *3^{3+1} m^5

Add :

m^{-12} *3^4m^5

Apply the addition rule for -12 + 5 :

3^{4} m^{-7}

Apply negative exponent rule for m^-7 :

3^4*\frac{1}{m^7}

Multiply the fractions :

\frac{1*3^4}{m^7}

\frac{81}{m^7}

Y=-2х - 4 y=x - 5 how many solutions does this have​
spayn [35]

Answer:

one solution

Step-by-step explanation:

-2x - 4 = x - 5

-3x - 4 = -5

-3x = -1

x = 1/3

y = 1/3 - 5

y = 1/3 - 15/3

y = -14/3

(1/3, -14/3)
