Graph the following inequality on the number line above. 3x < 12

1 answer:

4 0

We need to isolate x by diving 3 on both sides and you get x<4. To graph this, put an open circle around 4 (because 4 cannot be one of the solutions) and draw an arrow going left because x can be anything below 4

Perform the indicated opera 6) g(n)= n2 - 1 h(n)= 4n+1 Find (g. h)n)

DaniilM [7]

$(g.h)(n)\,\,is\,\,4n^3+n^2-4n-1\\$

Step-by-step explanation:

We are given:

$g(n)=n^2-1\\h(n)=4n+1$

We need to find (g.h)(n)

Finding (g.h)(n)

$(g.h)(n)=g(n).h(n)\\ (g.h)(n)=(n^2-1)(4n+1)\\ (g.h)(n)=n^2(4n+1)-1(4n+1)\\ (g.h)(n)=4n^3+n^2-4n-1\\$

So, $(g.h)(n)\,\,is\,\,4n^3+n^2-4n-1\\$

Find the value of x. х= 2 х= 3 х= 33 х= 52

nlexa [21]

Answer:

x = 3

Step-by-step explanation:

The external angle of a triangle is equal to the sum of the 2 opposite interior angles

∠ QRT is an external angle, thus

∠ QRT = ∠ RTS + ∠ RST, substitute values

45x = 25x + 57 + x

45x = 26x + 57 ( subtract 26x from both sides )

19x = 57 ( divide both sides by 19 )

x = 3
