Write in the line in slope-intercept form given the slope of 1/3, through the point (-6,9)
JulsSmile [24]

Answer:

<h2>         y = ¹/₃x + 11 </h2>

Step-by-step explanation:

A line passing through point (x₁, y₁) with the slope of m in point-slope form:

 y - y₁ = m(x - x₁)

m = ¹/₃

(-6, 9)      x₁ = -6,  y₁ = 9

So:

y - 9 = ¹/₃(x - (-6))

y - 9 = ¹/₃(x + 6)     ←    point-slope form

y - 9 = ¹/₃x + 2        {add 9 to both sides}

y = ¹/₃x + 11        ←  slope intercept form

Describe the relationship between the values of the digits in the number 9,999,999
Anit [1.1K]
Because all the digits are the same, each digit is worth 10x the one to its right and 1/10 of the one to its left.
This is because we count in base 10. This is also why we can expand this number to become
9*10^6+ 9*10^5+ 9*10^4+ 9*10^3+ 9*10^2+ 9*10^1 +9*10^0.

a school is planning an event. they want to give out small souvenir footballs to children 10 years and younger. 2/5 of people at
Alinara [238K]

Answer:

$84

56

Step-by-step explanation:

The event is attended by 560 people.

\frac{2}{5} of people attending are students.

So, the number of students = \frac{2}{5} \times 560 = 224

Again, \frac{1}{4} of all students are 10 years old or less.

So, the number of students of old 10 or less is \frac{1}{4} \times 224 = 56 (Answer)

The school wants to give out small souvenir footballs to children 10 years and younger. If each football costs $1.50 ,then  

the total cost for football is (1.5 × 56) = $84 (Answer)
