What is the 74th term of this arithmetic sequence? -25, -21, -17, -13,-9, -5,...

xz_007 [3.2K]

Answer:

267

Step-by-step explanation:

let's say that

f(0)=-25

so in the sequence we are adding 4

so f(1)=-25+4=-21

and f(2)=f(1)+4=-25+4+4=-25 + 4(2)

so if you continue you will notice that

f(n)=-25+4(n)

so our question is

What is the 74th term of this arithmetic sequence?

so if f(0) is our first term, the 74th will be f(73)

so we can apply our formula

f(73)=-25+4(73)

=-25+292

=267

The amount of sales tax varies directly with the cost of the purchase. If the sales tax is $3.80 on a purchase of $76 what would

polet [3.4K]

Answer:

The sales tax is equal to $\$2.3$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

Let

y-----> the cost of the purchase

x ----> the sales tax

step 1

Find the value of k

For $y=76, x=3.80$

substitute

$k=y/x$

$k=76/3.8$

$k=20$

The linear equation is equal to

$y=20x$

step 2

what would be the sales tax on a purchase of $46

For $y=46, x=?$

substitute in the equation

$46=20x$

$x=46/20$

$x=\$2.3$
