HELP PLEASEE!!! I just need help with the 2 boxes
Soloha48 [4]

Answer:

y= x - 300

y = -246 -- Her equivalent weight on earth

Step-by-step explanation:

Given

The attached table

Required

Fill in the gaps

(a) The equation

First, we calculate the slope (m)

m = \frac{y_2  - y_1}{x_2 - x_1}

From the table, we can say that:

(x_1,y_1) = (0,-300)

(x_2,y_2) = (300,0)

So, we have:

m = \frac{0  -(-300)}{300 - 0}

m = \frac{0 +300}{300}

m = \frac{300}{300}

m = 1

The equation is then calculated using:

y - y_1 = m(x - x_1)

This gives:

y - (-300) = 1(x - 0)

y +300 = 1(x)

y +300 = x

y= x - 300

(b) When x = 54

Substitute 54 for x in y= x - 300

y = 54 - 300

y = -246

ALGEBRA HELP!! Write an exponential function represented by the table.
marysya [2.9K]

Answer:

y=-50*0.2^x

Step-by-step explanation:

the formula for an exponential function is:

y=a*b^x

what do we multiply -50 by to get -10?

-50x=-10

x=-10/-50

x=1/5

x=2/10

x=0.2

This initial value here is -50, it is the first in the table

y=-50*0.2^x

You have earned $200 doing chores how long will it take to triple your money if you keep it in an account earning 4.25 compound
Alekssandra [29.7K]

Answer:

25.85 years

Step-by-step explanation:

Use the formula for continuous compounding amount:

A = Pe^(r*t), where r is the interest rate as a  decimal fraction, P is the initial amount, and t is the time in years.

Here we have:

A = $200e^(0.0425*t) = 3($200) (this is triple the original amount)

Solve this for t.  Divide both sides by $200 and then use natural logs:

1e^(0.0425*t) = 3

Then 0.0425*t = ln 3 = 1.0986

Dividing both sides by 0.0425 will isolate t:

       1.0986

t = --------------- = 25.85 years

       0.0425

What is the solution to the equation fraction 1 over 3x = 6?
8_murik_8 [283]

Hi there!

\large\boxed{\frac{1}{18}}

1/3x = 6

Begin by multiplying both sides by 3 to cancel the fraction:

1/x = 18

Take the reciprocal of both sides:

x = 1/18
