find VA
simplify fraction
set deonmenator equal to zero
that value is VA
cannot cross VA

fidn HA
if the degree of the numerator is less than the degree of the denomenator, then the HA is y=0
if the degree is equal, then divide he leading coeficient of the numerator by the leading coeficient of the deonmenator

to find if the fn crosses the HA, set the HA equaal to the reduced fn and solve, if you get a false statement, then it does not cross

holes are found by where if you have the numberator and deonmentoar are the same degree and they have a factor of same multiplicity example
f(x)= $((x+2)(x-3))/((x-3)(x-5))$
there is a hole at x=3 and to find the y coordinate, subsitute x=3 into reduced fraction

so

14.
make one fraction
f(x)=(2x-1)/(x-1)
x and y intercept
xint is f(x)=0
xintercept= 1/2 (1/2,0)
y intercept is when x=0 so set x=0
-1/-1=1
yintercept is y=1 aka (0,1)

VA set denom to zeero
x-1=0
x=1
VA at x=1

HA degree is same so divide leading coefs
2/1=2
HA at y=2

crosses HA?
2=(2x-1)/(x-1)
2x-1=x-1
x-1=-1
x=0
crosses ha at x=0 and
f(x)=(2(0)-1)/(0-1)=-1/-1=1
crosses HA at (0,1)

no holes

find where the fn is negative and positive
(2x-1) is zero at x=1/2
x-1 is zero at x=1
so in between, those, (1/2 and 1), the graph is negative (positive/negative=negative)
outside of that interval, the graph is positive (positive/positive=positive, negative/negative=negative) so graph is drawn on attachment

15. factor
f(x)=(x-2)/[(x-4)(x+1)]
VA set denom to zero
x-4=0
x+1=0
VAs at x=4 and -1

HA
degree of numberateor is smaller to HA is y=0

crosses HA?
0=(x-2)/(x^2-3x-4)
0=x-2
2=x
yes, at (2,0)

holes? no

find positive and negative

graph included

16.
VA=x is x=1
x=1
x-1=0
reduced denom is (x-1)
HA is y=2
degrees are same
2/1=2
(2x+something)/(x-1)
xint at -4,=
deonm when set to zero, etuals -4
2x+something=0 yeilds x=-4 so
2(-4)+something=0
-8+something=0
something=8

(2x+8)/(x-1)

hole at (6,4)
factored out bit is x=6
x=6
x-6=0

multiply whole equation by (x-6)/(x-6)

the function is
f(x)= $((2x+8)(x-6))/((x-1)(x-6))$ aka
f(x)= $(2x^2-4x-48)/(x^2-7x+6)$

17.
factor
f(x)= $((x+1)(x+5))/((x-2)(x+5))$
x+5=0
x=-5
hole at x=-5
sub into reduced fn (f(x)= $(x+1)/(x-2)$ )
4/7
hole at (-5,4/7)

degree is same so divide leading coeficients
1/1=1
HA=1

VA is set reduced denom to zero
(x-2) is reduced
x-2=0
x=2
VA is at x=2

In a population of 1,000 students, 50 were asked by random sampling what their plans were after graduation from high school. Their responses are shown in the table. A 2-column table with 4 rows. Column 1 is labeled Intention with entries College, job, military, no plans. Column 2 is labeled Number of students with entries 27, 13, 2, 8. Using proportional reasoning, make a prediction about how many students you would expect to have plans to attend college. 27 50 = x 1000 27,000 = 50x About would have plans to attend college.

The area of a rectangular ice skating rink is 900 square yards if the length of the rink is 100 yards what is the width of the rink ?

Answers

Well to find the area of a rectangle you have to go length times width.
If the area is 900 and the length is 100. You already have a basic equation.

100 times X = 900.
X will equal the width.

To get the answer, you have to reverse this equation so you divide the area by the length.

900 divided by 100. That comes to 9.
The width of the rectangle is 9. Hope this helped!:)
