Hello here is a solution :

<span>x²+6x+8 = x² +6x+(9-1)
              = (x²+6x +9) -1 
              =( x² +2(3)(x) +3² )-1 
</span>by identite : a²+2ab+b² = (a+b)²
x²+6x+8 = (x+3)² -1²
by identite : a²-b² = (a-b)(a+b)

x²+6x+8 = (x+3+1)(x+3-1) 
x²+6x+8 = (x+4)(x+2)

Y+5=-(x+5) in standard form
swat32

1. y+5=-x-5

2. y=-x-5-5

3.y=-x-10

4. y=x-10

_______________________

1. distribute negative sign

2. move the constant to the right and change the sign

3. -5-5 equals -10, bring everything down

4. change the sign of the x to positive, the equation is in standard form

Karen has 4h storyboiks. Karen's storybook collection is 2/3 of what Mary's collection is. How many storybooks do they have in a
Dafna11 [192]
In order to find out the answer , you just need to count :
Let's say that mary's collection is symbolized by x

2/3  x     =   4h

x             = 3/2 . 4h

x           =    6h

The storybooks they have in total would be : 6h  + 4h = 10 h

hope this helps

The graphed function, F(x), has a value greater than 0 over the intervals (-0.7, 0.76) and (0.76,  ∞) . F(x) > 0 over the intervals (-0.7, 0.76) and (0.76, ∞) is the correct statement [Fourth choice].

About a Graphed Function

The function graph of an object F stands for the set of all points in the plane that are (x, f(x)). The graph of f is also known as the graph of y = f. (x). The graph of an equation is thus a specific example of the graph of a function. A graphed function is a function that has been drawn out on a graph.

It is evident from the attached graph that the supplied function exceeds 0 for the following range:

-0.7 < F(x) < 0.76

And, 0.76 < F(x) < ∞

As a result, the intervals for which the given graphed function, F(x) is greater than 0 are as follows,

(-0.7, 0.76) and (0.76, ∞)
