Answer:

m= 1; b= 4

m= -4; b= 2

m= 1; b= 0

m= 3/2; b= -9

m= -7; b= 4/5

2. C

Step-by-step explanation:

Question 1.

Your slope equation is

To make ribbon and bow for a hat, Stacey needs 5/6 yard of black ribbon and 2/3 yard of red ribbon. how much total ribbon does s

larisa86 [58]

First make the denominators of the fractions the same by multiplying.

$\frac{2}{3}$ × $\frac{2}{2}$
= $\frac{4}{6}$

Now we just need to add the fractions together

$\frac{5}{6} + \frac{4}{6}$
= $\frac{9}{6}$

9/6 would be the answer, but it can be simplified further, then converted into decimal form.

$\frac{9}{6}$ ÷ $\frac{3}{3}$
= $\frac{3}{2}$
=1.5 yards

Your final answer is 1.5 yards of ribbon are needed.

Determine the inverse of the function. (show work please)

uysha [10]

Answer:

This is easy -- it's just a list of steps. At this level, the problems are pretty simple.

Let's just do one, then I'll write out the list of steps for you.

Find the inverse of f( x ) = -( 1 / 3 )x + 1

STEP 1: Stick a "y" in for the "f(x)" guy:

y = -( 1 / 3 )x + 1

STEP 2: Switch the x and y

( because every (x, y) has a (y, x) partner! ):

x = -( 1 / 3 )y + 1

STEP 3: Solve for y:

x = -( 1 / 3 )y + 1 ... multiply by 3 to ditch the fraction ... 3x = -y + 3 ... ditch the +3 ... subtract 3 from both sides ... 3x - 3 = -y ... multiply by -1 ... -3x + 3 = y ... y = -3x + 3

STEP 4: Stick in the inverse notation, f^( -1 )( x )

f^( -1 )( x ) = -3x + 3
