What is the graph of y-(-3)=-1/2(x-(0))?

1 answer:

3 0

Y - (-3) = -1/2(x - (0))
y + 3 = -1/2 x
y = -1/2 x - 3

The graph of the function is a straight line with a slope of -1/2.

Given f(x) = 2 / x-3 , find f(4)

Montano1993 [528]

Option #1:

$f(x)=\frac{2}{x-3}$

f(4), this means that x = 4

To find f(4), substitute/plug in 4 into "x" in the function:

$f(x)=\frac{2}{x-3}$ Plug in 4 into "x" since x = 4

$f(4)=\frac{2}{4-3}$

$f(4)=\frac{2}{1}$

f(4) = 2

Option #2:

$f(x)=\frac{2}{x} -3$

f(4), this means that x = 4

To find f(4), substitute/plug in 4 into "x" in the function:

$f(x)=\frac{2}{x} -3$

$f(4)=\frac{2}{4} -3$ To combine fractions, they need to have the same denominator. Multiply -3 by $(\frac{4}{4} )$ so that they have the same denominator.

$f(4)=\frac{2}{4} -3(\frac{4}{4} )$

$f(4)=\frac{2}{4} -\frac{12}{4}$ Combine the fractions

$f(4)=\frac{-10}{4}$ Simplify the fraction

$f(4)=-\frac{5}{2}$

PLEASE HELP!!! The right rectangular prism is packed with unit cubes of the appropriate unit fraction edge lengths. Find the vol

never [62]

--------------------------------------------------
Formula :
--------------------------------------------------
Volume = Length x Width x Height

--------------------------------------------------
Find volume :
--------------------------------------------------
$\text { Volume = } 4\dfrac{1}{4} \times 5 \times 2$

--------------------------------------------------
Change to improper fractions :
--------------------------------------------------
$\text { Volume = } \dfrac{17}{4} \times \dfrac{5}{1} \times \dfrac{2}{1}$

--------------------------------------------------
Combine into single fraction :
--------------------------------------------------
$\text { Volume = } \dfrac{170}{4}$

--------------------------------------------------
Simplify:
--------------------------------------------------
$\text { Volume = } 42 \dfrac{1}{2} \ cm^3$

--------------------------------------------------
Answer: Volume = 42 1/2cm³ (Answer c)
