Graph the following inequality and then select the correct graph below. x - y - 2 ≥ 0

-Dominant- [34]

Answer:

the graph in the attached figure

Step-by-step explanation:

we have

$x-y-2\geq 0$

Isolate the variable y

$-y\geq -x+2$ -----> Multiply by $-1$

$y\leq x-2$

The solution of the inequality is the shaded area below the solid line

The equation of the line is $y= x-2$

The slope of the line is positive

The y-intercept of the line is the point $(0,-2)$

The x-intercept of the line is the point $(2,0)$

Using a graphing tool

Find all of the missing angles of sides of the triangle below. Note that side lengths are in centimeters. Show and/or explain yo

FromTheMoon [43]

Answer:

c=19.21

<C=90

<B=38.66°

<A=51.34

Step-by-step explanation:

12²+15²=c²

144+225=c²

c=19.21

<C=90

For angle B, the sinB=Opposite over Hypotenuse

sinB=12/19.21

sinB=0.62467

B=sin^-1(0.62467)

<B=38.66°

To find A, 180-90-38.66

<A=51.34

If<br>A = i +3j -2K and B=4i-2j+4k<br>Find (2A+B).(A-2B)

Marizza181 [45]

GIVEN :

a = 1/√10 ( 3i + k) and

b = 1/7 ( 2i + 3j - 6k)

TO FIND :

( 2a- b) . [ ( a x b ) x ( a + 2b)]

SOLUTION :

◆Going with the equation given,

( 2a - b) . [ ( a x b ) x ( a + 2b)]

= (2a - b) [( a×b×a) + 2(a×b)×b]

◆BAC - CAB RULE,

A×B×C = B( A.B ) - C(A.B )

= (2a- b ) [ (b (a.a ) - a (a.b ) + 2b ( a.b) -2b (a.b]

Solving further

= (2a - b )(b - 2a)

= -4a.a -b.b

=-5.

Answer:

( 2 - b) . [ ( a x b ) x ( a + 2b)] = -5
