9x-6y=-20 through (0,-4)

Answers

Answer 1

Answer:

To make the equation go through (0,-4) the new equation would be 9x + 5y = 20. We needed to change it from subtracting to adding so the direction of the line would go from going down to up too up to down. In slope-intercept form the original equation would be found by the following.

9x - 6y = 20

-6y = 20 - 9x

y = -20/6 - (-9/6x)

y = 9/6x - 20/6

y = 3/2x - 10/3

To make the perpendicular line, take the slope and apply the opposite and reciprocal.

y = -2/3x - 10/3

Best of Luck!

Which is the graph of the function f(x) = x2 + 2x + 3?

Answers

Answer:

Refer the graph attached.

Step-by-step explanation:

Given : Equation $f(x) = x^2 + 2x + 3$

To find : The graph of the given equation?

Solution :

Let, $y= x^2 + 2x + 3$

First we find the points which satisfy the equation and then joining those points give you the graph.

Points are

x y

-3 6

-2 3

-1 2

0 3

1 6

Now, We plot these points.

The graph is the parabola with vertex (-1,2).

Find the 30th term of the following sequence. 1, 7, 13, 19, ... 174 175 180 181.

Answers

Checking if the sequence is an arithmetic sequence 7 - 1 = 6 13 – 7 = 6 Therefore the sequence is arithmetic, with a_0 = 1 and d = 6 a_n = a_0 + (n-1)d a_30 = 1 + (29)(6) = 175 Therefore the 30th term is 175.

the rule is : 6n - 5 to find the 30th term replace n with 30 6× 30 - 5 = 175
