Answer:

x + 6 + x + 6 + x + 6 + x + 6 + x + 6 x + 6 + x + 6 + x + 6 = 120

aka 8(6 + x) = 120

48 + 8x = 120

you want to get 8x on one side so you will subtract 48 on both sides - whatever you do to obe side you must do on the other side.

8x = 72

now you want the x by its self so to undo multiplication you need to divide, and divide on both sides.

x = 9

Solution: x = 9

What is 1/2+(-3 1/2)=

Anestetic [448]

Answer:

-3

Step-by-step explanation:

The equation could be written with decimals to make it easier:

0.5 + (-3.5) = ?

I am going to make an example

You owe your friend $3.50

That can be represented as this:

$-3.50

You pay your friend $0.50

Now you only owe your friend $3.00

Hope this helped :)

How do I use the following cosine equation to get the Sinusoid Max & Min Times (x values), and Sinusoid Max and Min Values (

Paraphin [41]

9514 1404 393

Answer:

maximum: (x, y) = (12.4n+3.2, 186.322)
minimum: (x, y) = (12.4n+9.4, 163.498)

Step-by-step explanation:

You know that cos(α) is a maximum at α=0, 2π, 4π, and all even multiples of π. You know cos(α) is a minimum for α=π, 3π, 5π, and all odd multiples of π.

You can find your value of x at which y will be a maximum by setting the argument of the cosine function equal to zero (and/or 2nπ). If we use α=2nπ, then we have ...

α = (5π/31)(x -3.2) = 2nπ

(x -3.2) = (31/5)(2n) = 12.4n

Tidal maxima will occur at ...

x = 12.4n +3.2 . . . . . for integer values of n

Without bothering to go through the solution for α being odd multiples of π, we can see from this that the period is 12.4 hours. We know the tidal minimum will be half a period later, or 6.2 hours later than this.

Tidal minima will occur at ...

x = 12.4n +9.4 . . . . for integers n

Of course, cos(α) has extremes of ±1, so your tidal maximum will be ...

y = 11.412 +174.91 = 186.322

and your tidal minimum will be ...

y = -11.412 +174.91 = 163.498

Slope: 0<br> y-intercept: -2<br> .

Nookie1986 [14]

Answer:

The linear equation is the equation of straight line. where m is the slope of the line and c is the y-intercept. Thus, the y-intercept is expressed as (0, c). That is where the graph intercepts the y-axis (thus, the x value would be 0).
