Factor completely 5x2 − 5x − 100.

Rama09 [41]

First, factor out 5:
5 (x² -x -20)
We need two numbers that add to -1 and multiply to -20. -5 and 4 satisfy this.
5(x-5)(x+4)

Make r subject of the formula <img src="https://tex.z-dn.net/?f=s%20%3D%204%5Cpi%20%5C%3A%20r%20%7B%7D%5E%7B2%7D%20" id="Tex

Answer:

r = √( s/4π)

Step-by-step explanation:

s = 4πr²

s/4π = 4πr²/4π

r² = s/4π

√(r²) =+/-√( s/4π)

r = √( s/4π) Because r is a radius of the circle , it should be positive.

Which ofnthe following shows the correct use of distributive property when solving 1/3(33-x)=135,2

madam [21]

Answer: OPTION C.

Step-by-step explanation:

The missing options are:

$A. (33 - x) = \frac{1}{3} * 135.2\\\\B. (\frac{1}{3} *33) - \frac{1}{3} x = \frac{1}{3} * 135.2\\\\C.(\frac{1}{3} * 33) - \frac{1}{3} x = 135.2\\\\D. (\frac{1}{3} * 33) + \frac{1}{3} x = 135.2$

In order to solve this exercise you need to remember the following:

1. The Distributive property states that:

$a(b+c)=ab+ac\\\\a(b-c)=ab-ac$

2. The multiplication of signs:

$(+)(+)=+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-$

In this case the exercise gives you the following equation:

$\frac{1}{3}(33-x)=135.2$

Since you need to solve for the variable "x" in order to find its value, the first step you must apply in the in the procedure is to eliminate the parentheses applying the Distributive property.

Then, you must multiply everyting inside the parentheses by $\frac{1}{3}$ .

Therefore,based on the explanation, you know that the correct use of the Distributive property is:

$\frac{1}{3}*33-\frac{1}{3}x=135.2$

Solve the system by graphing. 3x+8y=16 3x+8y=-64

Gnesinka [82]

-3x-y=10

4x-4y=8

or

y = -3x - 10

P(0,-10) and P(-2, -4) on this line: Plot and connect with the Line.

y = x - 2

P(0, -2) and (2,0) on this line: Plot and connect with the Line.

P(-2,-4) is the ordered pair that is the solution for this system of EQs

On may CHECK by substituting x= -2 and y = -4 into the EQs of these Lines

Hope this helps!!!
