Combine like terms to create an equivalent expression.
3.4 - 2.8d +2.8d - 1.3

Answers

Answer:

2.1

Step-by-step explanation:

Simplifying

3.4 + -2.8d + 2.8d + -1.3 = 0

Reorder the terms:

3.4 + -1.3 + -2.8d + 2.8d = 0

Combine like terms: 3.4 + -1.3 = 2.1

2.1 + -2.8d + 2.8d = 0

Combine like terms: -2.8d + 2.8d = 0.0

2.1 + 0.0 = 0

2.1 = 0

Solving

2.1 = 0

Couldn't find a variable to solve for.

This equation is invalid, the left and right sides are not equal, therefore there is no solution.

Rachel’s has a summer job working at the library. The graph below shows the relationship between the number of hours Rachael worked and the amount of money, in dollars, that Rachel earned?

Answers

Answer: m = 10 h

Step-by-step explanation: i did the test too

The Equation for Rachel Earning is m = 10h.

What is Slope?

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

From the graph we take two points (4, 35) and (5, 45).

So, the slope is

= (45 - 35) / (5-4)

= 10 /1

= 10

let Rachel work for h hours then Rachel earned

m = 10h

Find the 59th term of the arithmetic sequence 26,17,8

Answers

Answer:

-496

Step-by-step explanation:

The direct formula for the nth term of an arithmetic sequence is given by the formula:

[tex]x_n=a\cdot d(n-1)[/tex]

Where a is the initial term, d is the common ratio, and n is the nth term.

Let's find a and d.

From the sequence, we can see that the initial term or a is 26.

Also, each subsequent term is 9 less than the previous term. In other words, our common ratio is -9.

Therefore, our direct formula is:

[tex]x_n=26-9(n-1)[/tex]

To find the 59th term, substitute 59 for n:

[tex]x_{59}=26-9(59-1)[/tex]

Subtract:

[tex]x_{59}=26-9(58)[/tex]

Multiply:

[tex]x_{59}=26-522[/tex]

Subtract:

[tex]x_{59}=-496[/tex]

So, the 59th term is -496.

And we're done!
