What's the equation of the line that passes through the points (4,4) and (0,-12)?

Law Incorporation [45]

Answer:

Step-by-step explanation:

You need to find the slope.

$m=\frac{y_{2}-y_{1} }{x_{2}- x_{1} }\\m=\frac{-12-4 }{0-4 }\\m=\frac{-16}{-4}\\ m=4$

Since the slope is 4, the answer is B.

Find the solution to the given equation if the replacement set is {6, 9,15,16}.

Alexxandr [17]

They gave you a set of numbers that you replace the variable x in the equation to see if it gives a correct answer so just do exactly that.

6 + 2x = 24
6 + 2(6) = 24
6 + 12 = 24
18 = 24 so incorrect. both sides are not equal to each other.

6 + 2x = 24
6 + 2(9) = 24
6 + 18 = 24
24 = 24 so correct. both sides are equal to each other.

6 + 2x = 24
6 + 2(15) = 24
6 + 30 = 24
36 = 24 so incorrect. both sides are not equal to each other.

6 + 2x = 24
6 + 2(16) = 24
6 + 32 = 24
38 = 24 so incorrect. both sides are not equal to each other.

so your answer is b) 9

hope this helps, God bless!

ANSWER

$\boxed {f(n) = 7n - 4}$

EXPLANATION

From the table,

$a_1 = 3$

$a_2 = 10$

There is a constant difference of

$d = a_2 - a_1$

$d = 10 - 3 = 7$

The sequence is therefore an arithmetic progression.

The general formula for the arithmetic progression is

$f(n) = a_1 + (n - 1)d$

We substitute the values into the formula to obtain,

$f(n) = 3+ 7(n - 1)$

We expand the bracket to obtain,

$f(n) = 3+ 7n - 7$

This simplifies to

$f(n) =7n - 4$
