Answer:

make a graphical representation for our case do we have infinite lines pass through a point M?

Step-by-step explanation:

If the graphs of the equations do not intersect (for example, if they are parallel), then there are no solutions that are true for both equations. If the graphs of the equations are the same, then there are an infinite number of solutions that are true for both equations.

Which equation is the inverse of y = 16x2 + 1?

Llana [10]

Answer:

$y=\frac{\sqrt{x-1} }{4}$

Step-by-step explanation:

The given equation is

$y=16x^2+1$

For this function to have an inverse, we must restrict the domain, say $x\ge0$

We interchange x and y to get,

$x=16y^2+1$

We now make y the subject to get;

$x-1=16y^2$

$x-1=16y^2$

We divide through by 16 to get;

$\frac{x-1}{16}=y^2$

We now take the square root of both sides to get;

$\pm \sqrt{\frac{x-1}{16}}=y$

$y=\pm \frac{\sqrt{x-1} }{4}$

Since $x\ge 0$ , the inverse function is

$y=\frac{\sqrt{x-1} }{4}$

(25 PNTS!!) The area of a rectangle is 63 square meters. If the length of the rectangle is 2 m longer than its width, find the d

chubhunter [2.5K]

Answer:

w = 7m

l =9 m

Step-by-step explanation:

Let w = width

l = w+2

A = l*w

63 = (w+2) * w

63 = w^2 +2w

Subtract 63 from each side

0 = w^2 +2w - 63

Factor

What 2 numbers multiply to -63 and add to 2

9*-7 = -63

9-7 = 2

0 = (w +9) ( w-7)

Using the zero product property

w+9 =0 w-7 =0

w = -9 w = 7

Since we cannot have a negative length

w=7

l =w+2 =7+2 = 9
