7n +9 = -1+6(n+4)can someone walk me through this please?​

Mathematics
1 answer:
Ira Lisetskai [31]3 years ago
6 0

Answer:

n = 14

Step-by-step explanation:

7n +9 = -1+6(n+4)

Distribute

7n+9 = -1 +6n+24

Combine like terms

7n +9 = 6n +23

Subtract 6n from each side

7n -6n+9 = 6n-6n +23

n+9 = 23

Subtract 9 from each side

n+9-9=23-9

n = 14

A rabbit population doubles every 4 weeks.There are currently five rabbits in a restricted area. If t represents the time in wee
sertanlavr [38]
Doubling formula is this:

P(t)=P(2)^{\frac{t}{d}}
where P=initial number of rabbits
t=time
d=time it takes to doulbe

ok, so 4 weeks is the doubling time so that is 4*7=28 days

we wawnt time=98
and oroiginal number of rabbits is 5 so
P(98)=5(2)^{\frac{98}{28}}
P(98)=5(2)^{3.5}
P(98)=5(2^3)(\sqrt{2})
P(98)=5(8)\sqrt{2}
P(98)=40\sqrt{2}
so P(98)≈56.56
we can't have .56 rabbit so round down or up
about 56 or 57 rabbits in 98 days

Five years ago, John's age was half of the age he will be in 8 years. How old is he now?
Alexus [3.1K]
Answer:
26 year old

Step by step explanation:
Five years ago, John's age was half of the age he will be in 8 years.
this means that (x-5) = (x+8)/2
-----
solving for x, we get:
2 * (x-5) = x + 8
which becomes:
2x - 10 = x + 8
which becomes:
x = 18
-----
john is 18 years old now.
5 years ago john was 13
8 years from now john will be 26
13 = 1/2 * 26

For what values of k will the function y=6x^2-8x+k have one zero: Two zeros: No zeros
Feliz [49]

Answer:

Step-by-step explanation:

consider 6x^2-8x +k

disc .=(-8)^2-4*6*k=64-24k

it has no solution if 64-2k<0

or 64<2k

or 2k>64

k>32

it has two zeros if 64-2k≥0

or 64≥ 2k

or 2k≤64

or k≤ 32

it has one zero if Disc. =0

64-2k=0

2k=64

k=32
