Numbers like 10, 100, 1,000, and so on are called?

1 answer:

3 0

Numbers starting with a 1 and followed by only 0s (such 10, 100, 1,000,10,000, and so forth) are called powers of ten, and they're easy to represent as "exponents". Powers of ten are the result of multiplying 10 times itself any number of times.

Answer:

(x-10) (x+1) =0

x=10 x=-1

Step-by-step explanation:

x^2 -9x-10 =0

Factor

What two numbers multiply to -10 and add to -9

-10*1 = -10

-10+1=-9

(x-10) (x+1) =0

Using the zero product property

x-10 = 0 x+1=0

x-10+10=0+10 x+1-1=0-1

x=10 x=-1

These are the x intercepts

Answer: x=3

Step-by-step explanation:

To solve this problem you must apply the proccedure shown below:

- Multiply both sides of the equation by 3:

$3(2x-3)=3(\frac{x^2}{3})\\6x-9=x^{2}$

- Now you must make the equation equal to zero as following:

$6x-9=x^{2}\\x^{2}-6x+9=0$

- Factor it, as you can see below. Therefore, you obtain the following result:

$(x-3)(x-3)=0\\(x-3)^2=0\\x=3$
