Find the length cu. the triangles are similiar.

CU = 117

Step-by-step explanation:

Since we have similar triangles, we can use proportions.  Put the small triangle sides over the large triangle side.

WC             WD

=

WU             WV

26               20

=

36x-1             110

Using cross products

26*110 = 20* (36x-1)

Distribute

2860 = 720x - 20

Add 20 to each side

2860+20 = 720x-20+20

2880 = 720x

Divide by 720

2880/720 = 720x/720

4=x

We need to find CU

CU = WU - WC

Substituting in what we know

CU = 36x-1 -26

Since we know x=4

      = 36*4 -1 -26

      144 - 27

      = 117

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is
