Simplify completely ((x2-4x+4)/(x2+10x+25)) x ((x+5)/(x2+3x-10)) ...?

Ne4ueva [31]

First of all you'll have to
Factor x^2-4x+4 = (x-2)^2
Factor x^2+10x+25 = (x+5)^2
Factor x^2+3x-10 = (x+5)(x-2)

So you'll have (x-2)^2/(x+5)^2 X (x+5)/(x+5)(x-2)
Then cancel the (x-2) and (x+5) on both sides

Thus getting the answer of x-2/(x+5)^2
or x-2/x+10+25

Write an equation with the two points: (5,-2) and (3,4)

eimsori [14]

Answer:

$y=-3x-17$

Step-by-step explanation:

To find out the m(slope) of the equation use the formula:

$\frac{y_2-y_1}{x_2-x_1}$ .

Substitute the values:

$\frac{4--2}{3-5}$

Combine the values:

$\frac{6}{-2}$

Find the value of the fraction:

$-3$

M is -3.

The equation so far is $y=-3x+b$

To find the y intercept, substitute one pair of coordinates into the equation and solve for b:

$y=-3x+b\\-2=3*5+b\\-2=15+b\\-17=b$ .

We see that b =-17 so the full equation would be:

$y=-3x-17$ .

For the data in the table, does y vary directly with x? If it does, write an equation for the direct variation.

defon

I believe that it would be y = (13/8)x

Find the missing side of this right

lidiya [134]

Answer:

8

Step-by-step explanation:

If we assume the '17' is the hypotenuse ( the Q does not say)

then 15^2 + x^2 = 17^2 via the pythag theorem for right triangles

x = 8
