(x-4)^2-11

How?

$\\ \sf\longmapsto (x-4)^2-11$

$\\ \sf\longmapsto x^2-8x+16-11$

$\\ \sf\longmapsto x^2-8x+5$

Find the graph of the inequality y+2>-3(x+1)

Serhud [2]

Answer:

Below.

Step-by-step explanation:

y + 2 > -3(x + 1)

y + 2 > -3x - 3

y > -3x - 5

The graph will be the graph of the line y = -3x - 5 (dotted line), with the area above the line shaded.

Help me with this please also please show me how you got the answer so I understand it

Ilya [14]

We already know that C = 45. All we really need to do is simplify the equation and then solve for x.

45 = x + 0.06x + 0.08x + 0.1x
45 = (1 + 0.06 + 0.08 + 0.1)x
45 = 1.24x
x = 36.2903, which rounds to $36.29 for the haircut.

Identify all of the root(s) of g(x) = (x2 + 3x - 4)(x2 - 4x + 29)

vichka [17]

Answer:

x=-4,1,2+5i,2-5i

Step-by-step explanation:

Given is an algebraic expression g(x) as product of two functions.

Hence solutions will be the combined solutions of two quadratic products

$g(x) = (x^2 + 3x - 4)(x^2 - 4x + 29)\\$

I expression can be factorised as

$(x+4)(x-1)$

Hence one set of solutions are

x=-4,1

Next quadratic we cannot factorize

and hence use formulae

$x=\frac{4+/-\sqrt{16-116} }{2} =2+5i, 2-5i$
