What is the solution to x 4 – 12x 2 + 10 > 0?

Answer:

B. y= -2x+3

Step-by-step explanation:

1) the slope-interception form is: y=s*x+i, where s - slope, i - interception are unknown numbers;

2) if y(0)=3, then i=3, it means the equation is y=s*x+3;

3) if to substitute x=1; y=1 into the equation y=s*x+3, then s= -2. It means, the initial equation is y= -2x+3.

4) finally, the correct answer is B.

Answer:

28meters and 112meters

Step-by-step explanation:

one piece is x

the other is 4x

therefore; 4x+x=140

5x= 140

divide both sides by 5

x=28

4x=4(28)

=112

Answer:

Step-by-step explanation:

Do you have a picture of the problem? It's hard to solve without values

It depends but it's most like a A.

I'd say a 98/99% is an A+

Answer:

A 92% on any exam would just be an A, because it's closer to a 90% than an 100%.

Step-by-step explanation:

If it's a 95% or higher, then you can consider that an A+.

Hope this helps :)

Answer:

An slope-intercept form equation is written as y=mx+b. “m” is the slope and ”b” is the y-intercept. When we substitute the given values, the equation of the line in slope-intercept form is y=-1/4x+1.

Answer:

g( 1 ) = 9

Step-by-step explanation:

Remember that in linear functions expressed in the function notation, g(x), this means that for any allowed value of x, we can use the equation to find the corresponding value of g(x) or y (output). Thus, the linear function g(x) = 5x + 4 is essentially the same as expressing the given equation as: y = 5x + 4.  

Given the linear function, g(x) = 5x + 4, we can solve for x when g(x) = 9 by substituting the value of the output, g(x) = 9, into the function.

g(x) = 5x + 4

9 = 5x + 4

Subtract 4 from both sides:

9 - 4 = 5x + 4 - 4

5 = 5x

Divide both sides by 5 to solve for x:

[tex]\large\mathsf{\frac{5}{5}\:=\:\frac{5x}{5}}[/tex]

x = 1

Therefore, when g(x) = 9, the value of x = 1. Another way of expressing this is: g( 1 ) = 9.

Answer:

  (0, 1)

Step-by-step explanation:

The orthocenter is the point of intersection of the altitudes of the triangle. Each altitude is a line through a vertex and perpendicular to the opposite side.

In the attached, we labeled the points A, B, C in the order given. Side BC of the triangle is vertical, so the horizontal line through A will have equation ...

  y = 1

The line AC can be seen on the graph to have slope -1, so the altitude through point B will have slope 1. Its equation will be ...

  y = x+1

Then the point of intersection will be where ...

  y = y

  1 = x+1

  0 = x

That is, the orthocenter is the point (x, y) = (0, 1).

Answer:

-2 and 8.

Step-by-step explanation:

Isolate the m variable.

3m<4m+5

Subtract 4m from both sides.

-m<5

Divide both sides by -1.

m>-5

Solutions to this inequality are any number greater than -5 which is -2 and 8.

i can't see anything

Step-by-step explanation:

to divide by a fraction, you multiply by the reciprocal which just means reversing the fraction. so 8/ 1/3 is the same as 8 x 3.

Answer:

A. 2x - 1

Step-by-step explanation:

We want the price of each notebook, so we will get this equation.

(4x^2 + 2x + 1) / (8x^3 - 1)   [ The " / " sign means I wrote as a fraction. ]

After that, we will use this method to factor ( 8x^3 - 1 ).

a^3 - b^3 = ( a - b )( a^2 + ab + b^2 )

1 can be wrote as 1^3 as we still get the same answer.

8^3 - 1^3 = ( 2x - 1 )( 4x^2 + 2x + 1)

So, we will get this.

(4x^2 + 2x + 1) / ( 2x - 1 )( 4x^2 + 2x + 1)

Now, we can cross out the ( 4x^2 + 2x + 1 ).

We will be left with 1 / ( 2x - 1 ).

Flip it and we will get ( 2x - 1 )

And that is the answer.

I hope it helps.

Answer:  

y − 8 = m(x − 1)

72 minutes

Step-by-step explanation:

Point slope form is:  y − y1 = m(x − x1)

Pick any two points.  I'll pick (1,8) and (2,16).  I will make the first point the (x1,y1) we need for the point slope equation:

y − y1 = m(x − x1)

y − 8 = m(x − 1)

We can calculate the slope, m, by determining the Rise/Run of the line.  The Rise is the change in y for the Run, the change in x.

Change in Run (x) = (2-1) = 1

Change in Rise (y) = (16-8) = 8

Slope (Rise/Run) = 8

m is 8

y − 8 = m(x − 1)

y − 8 = 8(x − 1)

or

y = 8x

We can now predict Heather's time to complete the 9 miles:

y = 8x

y = 8*(9)

y = 72 minutes
