Answer:

119

Step-by-step explanation:

I believe you meant the question to be " m^4 + 1 / m^4, if m - 1 / m = 3. "

I presume that we want to take this second equation at hand here, and " simplify " it further. After doing so this first expression will have a value with respect to the simplified value of the equation, and, plugging in it's value we can solve for the expression (  m^4 + 1 / m^4. )

m - 1 / m = 3 - Take each value squared on either side of the equation,

( m - 1 / m )^2 = 3^2 - Simplify,

( m - 1 / m )^2 = 9

If you don't know how to expand expressions such as the one in the third step, " ( m - 1 / m )^2 " here is a quick recap. Remember that ( a - b )^2 = a^2 - 2ab + b^2. Therefore,

( m - 1 / m )^2 = m^2 - 2( m )( 1 / m ) + ( 1 / m )^2,\\( m - 1 / m )^2 = m^2 - 2 + 1 / m^2

Now let's continue,

m^2 - 2 + 1 / m^2 = 9 - Add 2 on either side,

m^2 + 1 / m^2 = 11

_______________

So now we have the " simplified equation " as you can say, for the equation. Let's " simplify " the expression now,

m^4+1/m^4 = 75+4(m^2+1/m^2) - Substitute the value of 11,

m^4+1/m^4 = 75+4(11),\\m^4 + 1 / m^4 = 119

Solution = 119

Which function has only one x-intercept at (-6, 0)?
Lelu [443]

Answer:

<h2>The function f(x) = (x - 6)(x - 6) has only one x-intercept. But at (6, 0) not at (-6, 0).</h2>

Step-by-step explanation:

The intercept form of a quadratic equation (parabola):

y=a(x-p)(x-q)

p, q - x-intercepts

Therefore

The function f(x) = x(x - 6) = (x - 0)(x - 6) has two x-intercepts at (0, 0) and (6, 0)

The function f(x) = (x - 6)(x - 6) has only one x-intercept at (6, 0)

The function f(x) = (x + 6)(x - 6) = (x - (-6))(x - 6)

has two x-intercept at (-6, 0) and (6, 0)

The function f(x) = (x + 1)(x + 6) = (x - (-1))(x - (-6))

has two x-intercepts at (-1, 0) and (-6, 0).

There are 7 boxes stacked on the floor in the math department supply closet. Each box has a height of 10 inches or 8 inches. The
Orlov [11]

Answer:

5 of the 7 boxes are 8 inches in height

Step-by-step explanation:

Mathematically;

1 ft = 12 inches

So, 5 ft will measure 5 * 12 = 60 inches

So from what we have ,

We want to combine 8 and 10 inches to give 60 inches total

Let the number of 10 inches be x and the number of 8 inches be y

Mathematically;

x + y = 7 •••••(i)

10x + 8y = 60 ••••(ii)

From equation i, x = 7-y

Put this in equation ii

10(7-y) + 8y = 60

70-10y + 8y = 60

70-60 = 10y-8y

2y = 10

y = 10/2

y = 5
