sum implies addition so add it with 4

i can’t put the equal to thing on here but there is supposed to be a line under the greater than symbol

Answer:

g\geq +/- 3i

Step-by-step explanation:

Using clues given in the problem, we can set up a solvable inequality.

A number g squared: g^{2}

The sum of a number g squared and 4: g^{2}+4

Is greater than or equal to: g^{2}+4\geq

Greater than or equal to -5: g^{2}+4\geq-5

Isolate g:

g^{2}\geq -9

Solve for g:

\sqrt{g^{2}}\geq \sqrt{-9}

This^ looks bad because of the negative, but as I'll show you in the next step it can be split up and you will use the value i, or \sqrt{-1}.

g\geq \sqrt{9} \sqrt{-1}

g\geq +/-3i

I hope this helps!

I NEED HELP ASAP!!!!! <br>PLEASEEEEE​
Yanka [14]

Answer:

5) y = -8x -4

6) y = 2x + 3

Step-by-step explanation:

Slope is rise over run. For the first problem, you went down 8 and over 1 to your next point. Going down means you have a negative slope. -8/1 is 8. Your y intercept is where the line meets the y axis. The line meets the y axis at -4.

The line meets a new point every time it goes over 1 and up 2. Rise over run means 2/1. The line goes up so the slope is positive. The line meets the y axis at 3

How to simplify this expression ?
Musya8 [376]

Answer:

\large \boxed{\sf \ \ \dfrac{1}{x^2}+\dfrac{1}{x^2+x}=\dfrac{2x+1}{x^2(x+1)} \ \ }

Step-by-step explanation:

Hello,

This is the same method as computing for instance:

\dfrac{1}{2}+\dfrac{1}{3}=\dfrac{3+2}{2*3}=\dfrac{5}{6}

We need to find the same denominator.

Let's do it !

For any x real different from 0, we can write:

\dfrac{1}{x^2}+\dfrac{1}{x^2+x}=\dfrac{1}{x^2}+\dfrac{1}{x(x+1)}\\\\=\dfrac{x+1+x}{x^2(x+1)}=\dfrac{2x+1}{x^2(x+1)}

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

Jacob made a banner for a sporting event in the shape of a parallelogram the area of the banner is 127 1/2 square centimeters th
Firlakuza [10]
For a parallelogram, the area is calculated by the equation,
                                            A = bh
where A is area, b is base, and h is height. From this equation, we can solve for the base of the banner by dividing the area by the height. 
                        base of the banner = 127.5 cm² / 4.25 cm
                         base of the banner = 30 cm
Thus, the measure of the base of the banner is equal to 30 cm.

The value of Adam's model railway is $550.
garik1379 [7]

Answer:(c)

Step-by-step explanation:

Given

The initial value of Adam's model is A_o=\$550

the value increases exponentially with the rate of r\%

Time period t=5\ years

Final amount A=\$736

Exponential growth is given by

\Rightarrow A=A_o(1+r)^t

Putting values

\Rightarrow 736=550(1+r)^5\\\\\Rightarrow (1+r)^5=1.338

\Rightarrow 1+r=1.05999\\\Rightarrow r=0.05999\ or\ 5.99\%\approx 6\%

Option (c) is correct
