Answer:
the slope is -3/4
Step-by-step explanation:
this is because you need to do rise/run not run/rise, you set it up as a table
<u>x l y</u> Then, you would just find the difference between the two x coordinates and the two y coordinates, and find whether they increase or decrease
-3,5 you can see that from -3 to postive 1 there
1,2 is an increase of 4. you can also see that from 5 to 2 there is a decrease of 3. The y and x point have to flop places to become rise/run and it shows that the slope is -3/4 :) i hope this helps
Answer:
The difference is 
Step-by-step explanation:
We must find the common denominator of the fractions.
The common denominator of
and
is
; therefore we have


now it is easy to subtract
using the number line: we have to move
units to the left in order to get to
.
Thus our answer is

Answer:
a) 
b) 
c) 
Step-by-step explanation:
<u>For the question a *</u> you need to find a polynomial of degree 3 with zeros in -3, 1 and 4.
This means that the polynomial P(x) must be zero when x = -3, x = 1 and x = 4.
Then write the polynomial in factored form.

Note that this polynomial has degree 3 and is zero at x = -3, x = 1 and x = 4.
<u>For question b, do the same procedure</u>.
Degree: 3
Zeros: -5/2, 4/5, 6.
The factors are

<u>Finally for the question c we have</u>
Degree: 5
Zeros: -3, 1, 4, -1
Multiplicity 2 in -1
