The y intercept is what the y value is when x is 0.

Set X to 0 and solve:

-2/9(0) + 1/3

0 + 1/3 = 1/3

The y-intercept is 1/3

Addy’s monthly water bills for last year are $27, $31, $30, $26, $25, $27, $37, $33, $32, $28, $26, $26. Express the formula for

Sav [38]

Answer:

Σ( xi ) / n ; $29

Step-by-step explanation:

Given the following data:

X= $27, $31, $30, $26, $25, $27, $37, $33, $32, $28, $26, $26

Number of observations (n) = 12

Mean formula (m) = ( Σ xi ) / n

Where i = each individual value in X

Mean water bill for the years is thus :

m = Σ [(27 + 31 + 30 + 26 + 25 + 27 + 37 + 33 + 32 + 28 + 26 + 26)] / 12

m = 348 / 12

m = 29

Hence, the mean water bill for the year is $29

Choose the correct solution and graph inequality q + 1/3 > 1/2

kherson [118]

Answer:

first choice

Step-by-step explanation:

make 1/3 and 1/2 a common denominator, which is 6.

1x2

- = 2

3x 2 6

1 x 3

- = 3

2 x 3 6

now u have 2/6, and 3/6

u subtract 2/6 by 3/6 since ur finding a solution to an inequality. remember to do the opposite sign.

2/6-2/6 = 0 (u cancel that out)

3/6 - 2/6 = 1/6

now u have

q>1/6

since there's no 1/6 the first choice is the most accurate

What is a equation that has a zero of -2 with a multiplicity of 3, a zero of 1 with a multiplicity of 1, degree of 4, and rises

zloy xaker [14]

Answer:

x^4+8x^3+18x-27=0

Step-by-step explanation:

In a equation of the form

$(x-a)^n(x-b)^m=0$

you have roots in x=a and x=b, and multiplicity of n and m respectively.

Hence, the equation is

$(x-(-2))^3(x-1)=0\\(x+2)^3(x-1)=0\\$

by expanding the factors you have

$(x^3+3x^2(3)+3x(3)^2+(3)^3)(x-1)=0\\(x^3+9x^2+27x+27)(x-1)=0\\x^4+9x^3+27x^2+27x-x^3-9x^2-27x-27=0\\x^4+8x^3+18x^2-27=0$

8 – 3(k + 2) = 2 – 3k

Mkey [24]

Answer:

the answer is 0

Step-by-step explanation:

you distribute the 3 which gives

8 - 3k - 6 = 2 - 3k

then you combine like terms and end up with

2 - 3k = 2 - 3k

then you subtract 2 on each side which gives

- 3k = - 3k

and then when you have to keep combining like terms so you add the 3k on both sides which gives u 0
