Answer:

a_{n}=7n-10

Step-by-step explanation:

Givens

a_{1}=-3\\a_{n}=a_{n-1} +7

The formula to find the iterative rule of an arithmetic sequence is

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

Where d=7 and a_{1}=-3, replacing these values, we have

a_{n}=-3+(n-1)7\\ a_{n}=7n-7-3\\ a_{n}=7n-10

Therefore, the right answer is the first choice: a_{n}=7n-10

What is the equation of the line, in point-slope form, that passes through the points (9, 1) and (4, 16)?
Nat2105 [25]

Answer:

<h2>B. y - 1 = -3(x - 9)</h2>

Step-by-step explanation:

The point-slope form of an equation of a line:

y-y_1=m(x-x_1)

m - slope

(x₁, y₁) - point

The formula of a slope:

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

We have the points (9, 1) and (4, 16). Substitute:

m=\dfrac{16-1}{4-9}=\dfrac{15}{-5}=-3

y-1=-3(x-9)

A function is a relationship that maps__.
g100num [7]

Solution:

A function is always a relation but a relation is not always a fucntion.

For example

we can make a realtion of student roll number and their marks obtained in mathematics.

So we can have pairs like (a,b), (c,d)..etc.

Its a realtion but it may not be function. Because function follows that for same input there should not be diffrent output, aslo there could be many inputs to one output in the case of constant function . But this doesn't holds a necessary condition in case of relation.

Because two diffrent students with two diffrent Roll number may have same marks.

Hence the foolowing options holds True in case of a function.

A) many inputs to many outputs or one input to one output.

D) one input to one output or many inputs to one output.

neonofarm [45]

Answer:

$24.

Step-by-step explanation:

I multiplied 4 by 7 to get 28. Then I multiplied $28 by three weeks and got $84. Since $84 is more than I owe I subtracted $84 by $60 and got $24. I would give my friend $60 and keep $24. Hope this helps! Have a great day!
