Answer:

$9.56

Step-by-step explanation:

$13.00 x .30 = 3.90

13.00 - 3.90 = $9.10 x .05 = 0.46

$9.10 + 0.46 = 9.56

50PTS! Describe the vertical asymptotes and holes for the graph of y = x-5/x^2 -1

Diano4ka-milaya [45]

Ok

first of all, for q(x)/p(x)
if the degree of q(x) is less than the degree of p(x),then the horizontal assemtote is 0

then simplify
any factors you factored out is now a hole, remember them

to find the vertical assemtotes of a function, set the SIMPLIFIED denomenator equal to 0 and solve

so

y=(x-5)/(x^2-1)
q(x)<p(x)
horizontal assemtote is y=0

no factors to simplify so no holes

set denomenator to 0 to find vertical assemtote
x^2-1=0
(x-1)(x+1)=0
x-1=0
x=1

x+1=0
x=-1

the horizontal assemtotes are x=1 and -1

Write an equivalent expression to present patricia total earnings this week 7h + 135 + 5h = ?h + ?

Paul [167]

Answer: 12 h + 135

Step-by-step explanation: 7h +135 + 5h = ?h + ?

7h +5h +135

=12h +135

So u combine like terms together which are 7h and 5h which gives you 12 h.And then you have 135 left,so you add 12h to 135.

Ps.If you don't know what like terms are.I will explain down below.

Like terms are variable that are the same.For an example 4y and 3y are like terms .Another example is 1/3 xy and 6xy .

Marge cut 16 pieces of tape for mounting pictures on poster board. Each piece of tape was 3/8 inch long. How much tape did Marge

mafiozo [28]

Hi! :)

It sounds like you need to multiply this fraction.

$\frac{3}{8}$ *16=6

So, Marge used 6 total inches of tape.

Hope this helps!

Answer:

9) x=58

10) r=4

11) m=4

12) p=3

13) x=6

14) x=-3

15) s=400

Step-by-step explanation:

9) x+2/5=12

x5 x5

x+2=60

-2 -2

x=58

10) 7r + 14 - 3r =30

-14 -14

7r-3r=16

4r=16

÷4 ÷4

r=4

11) $\frac{4}{5}$ m+2=6

-2 -2

$\frac{4}{5}$ m=4

÷ $\frac{4}{5}$ ÷ $\frac{4}{5}$

m=4

12) 2(5p+9)=48

10p+18=48

-18 -18

10p=30

÷10 ÷10

p=3

13) 5(2x-8)=20

10x-40=20

+40 +40

10x=60

÷10 ÷10

x=6

14)6(3-2x)=54

18-12x=54

-18 -18

-12x=36

÷-12 ÷-12

x=-3

15) $\frac{2s}{5}$ - $\frac{s}{2}$ =40

x5 x5

2s- $\frac{s}{2}$ =200

x2 x2

2s-1s=400

1s=400
