If h (r)= 2/3 r - 6, what is the value of h(-9)?

Bad White [126]

Answer:

$h(-9)=-\frac{2}{33}$

Step-by-step explanation:

The given expression is $h(r)=\frac{2}{3r-6}$

We want to find the value of h(-9).

We substitute r=-9 to obtain:

$h(-9)=\frac{2}{3(-9)-6}$

We multiply out to obtain:

$h(-9)=\frac{2}{-27-6}$

We simplify the denominator to obtain:

$h(-9)=\frac{2}{-33}$

This is the same as:

$h(-9)=-\frac{2}{33}$

Write an equation of the line in slope- intercept form

gavmur [86]

Answer:

$a)\ y=-\frac{1}{3}x$

Step-by-step explanation:

Slope (m) form: $\frac{y_2-y_1}{x_2-x_1}$

$m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{1-0}{-3-0} \\\\m=\frac{1}{-3} \\\\m=-\frac{1}{3}$

$y=mx+b\\y=-\frac{1}{3}x +b$

(0, 0)

$y=-\frac{1}{3}x +b\\0=-\frac{1}{3}(0) +b\\0=0+b\\0=b$

$y=-\frac{1}{3}x +0\\y=-\frac{1}{3}x$

Check your answer:

$y=-\frac{1}{3}x \\1=-\frac{1}{3}(-3)\\1=-1$

This statement is true

Hope this helps!

Write the linear eqaution in slope form for x and y. 1/3x+y=-2

Anit [1.1K]

Answer:

y = -1/3x -2

Step-by-step explanation:

Slope intercept form of a line is

y= mx+b

We need to solve for y

1/3x +y = -2

Subtract 1/3x from each side

1/3x -1/3x +y =-1/3x -2

y = -1/3x -2
