What equation is the inverse of 5y+4=(x+3)2+1/2

1 answer:

7 0

Start off by "switching" the variables

$\bf 5\boxed{y}+4=(\boxed{x}+3)^2+\cfrac{1}{2}\qquad inverse\implies 5\boxed{x}+4=(\boxed{y}+3)^2+\cfrac{1}{2}$

then solve for "y"

5^2 + 3^2 (equals to 34) ; That's the wrong expression

It should look like this : (5+3)^2 (which equals to 64)

To describe a specific arith-

Bezzdna [24]

Answer:

$f(x) = 7x + 30$

Step-by-step explanation:

We need at least two points to write the equation of a straight line.

The recursive formula that Elijah wrote is:

$f(0) = 30$

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

When we substitute n=0, we get:

$f(0 + 1) = f(0) + 7$

$f(1) = 30 + 7$

$f(1) = 37$

The points (0,30) and (1,37) lies on this line.

The equation of this line is of the form:

$f(x) = mx + b$

where b =30 is the y-intercept and m=7 is the slope.

We plug in these values to get:

$f(x) = 7x + 30$

Note that the slope of the line is equal to the common difference of the Arithmetic Sequence.

You could also use the two points to find the slope:

$m = \frac{37 - 30}{1 - 0} = 7$

5x+4y=-14 <br>3x+6y=6<br> solve the system below by the elimation

lana66690 [7]

Answer:

y = 4

x = -6

Step-by-step explanation:

multiply first equation by 3

3×(5x+4y)= -14 ➡ 15x + 12y = -42

multiply second equation by -5

-5×(3x+6y)= 6➡ -15x -30y = -30

now add both equations up

15x +12y -15x -30y = -42 -30 (15x will eliminate -15x)

-18y = -72

y = 4 use this to find value of x

3x + 6×4 = 6 ➡ ex = -18 ➡ x = -6
