Answer:

Well a midpoint makes the cutter segment or Line in exactly in half. So the two lines cutted are equal. In this case t is the midpoint. PT and TQ are equal. So you have two expressions, make then equal to each other since they are congruent.

6x+4=8x-8

12=2x

x=6

Now PT is 6x+4

So we subsitute x for 6 since x=6

6*6+4

PT is 40

If h(x) = 2/3x -9, find h(-6)

Maurinko [17]

Step-by-step explanation:

$h(x) = \frac{2}{3} x - 9$

$h( - 6) = \frac{2}{3} ( - 6) - 9$

$= - 4 - 9$

$= - 13$

Which equation represents the function graphed on the coordinate plane? g(x) = |x Ă˘â‚¬"" 4| Ă˘â‚¬"" 10 g(x) = |x 4| Ă˘â‚¬"" 10

natta225 [31]

The equation which represents the function graphed on the coordinate plane given is,

$|x+4|-10$

Thus, option B is the correct option.

Given-

The general form of the equation is,

$y=a|x-h|+k$

Let's compare it with the graph given. The graph opens upward with a slope of 1. Hence the value of $a$ is 1.

$y=|x-h|+k$

The vertex of the graph is shifted -4 to the right. Thus the value of the $h$ is -4.

$y=|x-(-4)|+k$

$y=|x+4|+k$

The graph is 10 down from the origin and hence, the value of k is -10.

$y=|x+4|-10$

Hence, The equation which represents the function graphed on the coordinate plane given is,

$|x+4|-10$

Thus, option B is the correct option.

X - y =2 X + y= -3<br> What is (x,y)

Dimas [21]

Answer:

(-1/2,-5/2)

Step-by-step explanation:

x-y = 2

x+y = -3

---------------

Through Elimination, we can just add the system of equations. The y cancels out and gives us the single equation for x:

2x = -1

x = -1/2

Substitute -1/2 for x in either equation and you get:

(-1/2) + y = -3 Solve for y

y = -5/2

What are the zeros of the function?

cluponka [151]

The function is:

f ( x ) = x² - x - 72

This is a quatdratic function. So we can find the zeroes of the function with the formula:

x 1/2 = ( - b +/- √(b² - 4 ac) ) / ( 2a )

And we have: a = 1, b = - 1 and c = - 72

x 1/2 = ( 1 +/- √((-1)² - 4 · 1· ( - 72 )) ) / 2

x 1/2 = ( 1 +/- √( 1 + 288 ) ) / 2

x 1/2 = ( 1 +/- √289 ) / 2

x 1/2 = ( 1 +/- 17 ) / 2

x 1 = ( 1 - 17 ) 2 = - 16 / 2 = - 8

x 2 = ( 1 + 17 ) / 2 = 18 / 2 = 9

Answer: The zeroes are - 8 and 9.
