3 0

Answer:

1-True

2-True

3-False

Step-by-step explanation:

1- All negative numbers are <0 and to the left on a number line. All positive numbers are >0 and are on the right of a number line.

2- When the number line moves to the right, the number gets larger.

3- You could have a negative number that is smaller than another number, but its distance from 0 could be greater. For example, -12 < 2. However, -12 is 12 places away from zero on the number line, but the number 2 is only two places away from zero on the number line.

To convert centimeters to inches, we multiply the measurement in centimeters by 2.54. identify the type of relation between cent

Westkost [7]

Hey there! Hello!

This can be represented by the equation y=2.54x, where:

y=measurement in inches
x=measurement in cm

You can plug any value into this problem to reveal that this is a linear function. I provided a graph of this to further prove the point.

Hope this helped you out, feel free to ask any additional questions if you need further clarification! :-)

What s the factor of (x+3)(x+2)

Virty [35]

<span>Simplifying (x + 3)(x + 2)

Reorder the terms: (3 + x)(x + 2)

Reorder the terms: (3 + x)(2 + x)

Multiply (3 + x) * (2 + x) (3(2 + x) + x(2 + x)) ((2 * 3 + x * 3) + x(2 + x)) ((6 + 3x) + x(2 + x)) (6 + 3x + (2 * x + x * x)) (6 + 3x + (2x + x2))

Combine like terms: 3x + 2x = 5x (6 + 5x + x2)

Factor a trinomial. (3 + x)(2 + x)

Final result:
(3 + x)(2 + x)</span>

Simplify (10-10i)/(-5i)

Phoenix [80]

Answer:

Step-by-step explanation:

$i-\text{imaginary\ unit}\\\\i=\sqrt{-1}\to i^2=-1\\\\=====================$

$\dfrac{10-10i}{-5i}=\dfrac{10}{-5i}+\dfrac{-10i}{-5i}=\dfrac{(10)(i)}{(-5i)(i)}+2=\dfrac{10i}{(-5)(i^2)}+2\\\\=\dfrac{10i}{(-5)(-1)}+2=\dfrac{10i}{5}+1=2i+2=2+2i$
