The graph of y = h (x) is a line segment joining the points (-7,-5) and (-1,-2) drag the endpoints of the segment below to graph

sertanlavr [38]

Answer: Ok, i cant drag the endpoints of the segment, but i can tell you how to do it.

First, we know that h(x) joins the points (1, -5) and (9, 1), then h(x) is a line:

h(x) = s*x + b

First, for a line that goes through the points (x1, y1) and (x2, y2), the slope will be:

s = (y2 -y1)/(x2 - x1)

Then in this case, the slope is:

s = (1 - (-5))/(9 - 1) = 0.75

Then we have

h(x) = 0.75*x + b

now, the value of b can be found as:

h(1) = -5 = 0.75*1 - b

b = - 5 - 0.75 = -5.75.

Then our equation is:

h(x) = 0.75*x - 5.75

Now, i gues you want to find the graph of:

y = h(-x)

Then our new function is:

g(x) = h(-x) = -0.75*x - 5.75.

Now to find the points, we evaluate this function in the same values of x as before.

g(1) = -0.75*1 - 5,75 = -6,5

the point is (1, -6.5)

the second point is when x = 9.

g(9) = -0.75*9 - 5.75 = -12.5

The second point is (9, -12.5)

Given JKMN is a square and NM= 4x and KM = 6x - 16, find all missing angle measures and side lengths.

kirza4 [7]

Answer:

The side lengths are 32 units each

Step-by-step explanation:

Given

$NM= 4x$

$KM = 6x - 16$

Required

The side lengths and missing angles

Since JKMN is as square, then:

$NM = KM$ -- all sides are equal

$4x = 6x - 16$

Collect like terms

$4x - 6x = - 16$

$-2 x = - 16$

Divide by -2

$x = 8$

Substitute $x = 8$ in $NM= 4x$

$NM = 4 * 8$

$NM = 32$

The missing angles can't be solved without an attachment.

However, if the missing angles are the angles at the edges of the square, then they measure 90 degrees each (i.e. angles at right angle)
