What is the inverse of the function shown?

Umnica [9.8K]

Answer:

The inverse is y = x + 5

Step-by-step explanation:

The general equation of a straight line is;

y = mx + c

In this case , the y-intercept is -5

So the partial equation is;

y = mx - 5

To get m, we use the x-intercept

The x-intercept coordinate is (5,0)

Insert this in the equation , we have;

0 = 5m-5

5m = 5

m = 5/5

m= 1

The equation of the line is thus;

y = x-5

So we want to find the inverse of this;

Replace x with d

y = d-5

Make d the subject of the formula

d = y + 5

replace d with x

x = y + 5

now replace x with y

So we have

y = x + 5

What is the sum of the first 37 terms of the arithmetic sequence?

lidiya [134]

Answer:

The sum of the first 37 terms of the arithmetic sequence is 2997.

Step-by-step explanation:

Arithmetic sequence concepts:

The general rule of an arithmetic sequence is the following:

$a_{n+1} = a_{n} + d$

In which d is the common diference between each term.

We can expand the general equation to find the nth term from the first, by the following equation:

$a_{n} = a_{1} + (n-1)*d$

The sum of the first n terms of an arithmetic sequence is given by:

$S_{n} = \frac{n(a_{1} + a_{n})}{2}$

In this question:

$a_{1} = -27, d = -21 - (-27) = -15 - (-21) = ... = 6$

We want the sum of the first 37 terms, so we have to find $a_{37}$

$a_{n} = a_{1} + (n-1)*d$

$a_{37} = a_{1} + (36)*d$

$a_{37} = -27 + 36*6$

$a_{37} = 189$

Then

$S_{37} = \frac{37(-27 + 189)}{2} = 2997$

The sum of the first 37 terms of the arithmetic sequence is 2997.

Eleanor and her little sister Joanna are responsible for two chores on their family’s farm, gathering eggs and collecting milk.

iris [78.8K]

Answer:

4 dozens

Step-by-step explanation:

Find Eleanor and Joanna's ratio of eggs to milk

Eleanor:

Dozen eggs : gallons of milk

9 : 3

3 : 1

Joanna:

Dozen eggs : gallons of milk

2 : 2

1 : 1

They gather one gallon of milk each which means Joanna has 1 dozen eggs and Eleanor has 3 dozens of eggs.

Total dozen of eggs = 3 + 1 = 4

Therefore, total dozen of eggs the family have per week is 4 dozens.
