Answer:

x = 80

Step-by-step explanation:

Combine − 3/5x and 7/20x to get -19/20x.

Then combine -19/20x and 1/4x and you get -7/10x.

Then you multiply both sides by -10/7 which is the reciprocal of -7/10.

Make -56(-10) one fraction.

Multiply -56 and -10 and you get 560.

Then divide 560 by 7 to get 80.

Two functions f and g are given. Show that the growth rate of the linear function is constant and that the relative growth rate

joja [24]

Answer:

linear function growth rate: 8.5

Step-by-step explanation:

The growth rate of the linear function is the coefficient of t: 8.5. (It is a constant.)

The growth rate of g(t) is its derivative: g'(t) = (1/8)(160e^(t/8)) = 20e^(t/8). Then the relative growth rate is ...

g'(t)/g(t) = (20e^(t/8))/(160e^(t/8)) = 20/160 = 1/8

It is a constant.

Please help me with this question

jek_recluse [69]

A is the correct answer

E is 90 degrees

ABE is 52 so EBD is 64
$(180 - 52) \div 2 = 128 \div 2 = 64$

so D is 26:
$180 - (90 + 64) = 180 - 154 \\ = 126$

good luck

Find the 61st term of -12, -28, -44,

Citrus2011 [14]

Answer:

$a_{61}=-972$

Step-by-step explanation:

<u>Arithmetic Sequences</u>

The arithmetic sequences are identified because any term n is obtained by adding or subtracting a fixed number to the previous term. That number is called the common difference.

The equation to calculate the nth term of an arithmetic sequence is:

$a_n=a_1+(n-1)r$

Where

an = nth term

a1 = first term

r = common difference

n = number of the term

We are given the first terms of a sequence:

-12, -28, -44,...

Find the common difference by subtracting consecutive terms:

r = -28 - (-12) = -16

r = -44 - (-28) = -16

The first term is a1 = -12. Now we calculate the term n=61:

$a_{61}=-12+(61-1)(-16)$

$a_{61}=-12-60*16=-12-960$

$\mathbf{a_{61}=-972}$

The price of a train ticket from Austin to Phoenix is normally $142.00 however, the train company is offering a special 65% disc

timofeeve [1]

Answer:

The sale price of a ticket from Austin to Phoenix for someone under 12 is $49.70

Step-by-step explanation:

Let

x----> the sale price of a ticket from Austin to Phoenix for someone under 12

we know that

100%-65%=35%=35/100=0.35

x=0.35*($142.00)

x=$49.70
