What is the equation of the line x–3y=18 in slope-intercept form?
olya-2409 [2.1K]
Solve the equation for y 

x-3y= -18

-3y = -18-x

now, divide both sides with -3

y = (-18-x)/-3

y = 6 +x/3

your slope is 1/3

and y-intercept is 6

If the graph of f(x) has the point (2,7) then what is one point that will be on the graph of f-1(x)
IRINA_888 [86]

The graph of f^-1 (x) is called the inverse function of f (x). The relationship between the two is that the point (x,y) is on the graph of f (x) if and only if the point (y,x) is on the graph of f^-1 (x).

This means that if the point (2, 7) is on f (x), therefore the point (7, 2) is on f^-1 (x).

Which of the following are prime factorizations of the number 70? Check all<br> that apply.
Shtirlitz [24]

The prime factorization of 70 is 2*5*7

Further explanation:

First of all let us define prime factorization

Prime factorization consists of all the prime multiples of a number i.e. the factors should also be prime numbers

Given number is 70

The multiples of 70 are

70 = 2*35 => 35 is composite number

70 = 5*14 => 14 is a composite number

70 = 7*10 => 10 is a composite number

70 = 2*5*7 => All factors are prime so

The prime factorization of 70 is 2*5*7
