Answer:

Zero

Step-by-step explanation:

because:

4x - 8 -4x = 9

combine like terms:

4x - 4x = 0x

then look at the equation:

-8 = 9

this is not true. therefore, it has no solutions.

Hope this helped!!

PLZ HELP AND EXPLAIN THIS PLZ

AURORKA [14]

Answer:

A. 4 trucks will make $80 because 4 × 20 = 80, so they need to wash 38 cars to make the other $380 because 38 × 10 = 380.

($80 + $380 = $460)

B. 15 trucks will make $300 because

15 × 20 = 300, so they need to wash 16 cars to make the other $160 because 16 × 10 = 160. ($300 + $160 = $460)

C. 21 trucks will make $420 because

21 × 20 = 420, so they need to wash 4 cars to make the other $40 because 4 × 10 = 40.

($420 + $40 = $460)

D. 27 trucks will make $540, so they won't have to wash any cars because they would have already exceeded their goal of $460.

Not sure what to do for letter E. Sorry. I hope the rest makes sense though :)

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
