Can someone help me solve this?!

To solve an inequality, you solve it just like an equation with an = sign

y-3 ≥ -12
Add 3 to both sides
y ≥ -9

What this means is that y could be any number as long as it’s greater than (bigger) or equal to -9, so y could equal -9, -3, 100, or 0 but could not equal -10,-11, -9.3, or anything less than -9

To graph this, first write in numbers below each of the lines. You want to show -9, a few numbers less than -9 and a few numbers greater than -9. It could look like this:

-11 -10 -9 -8 -7 -6 -5

Then, draw a filled in circle above -9. This shows that y can equal -9. Starting from where you drew the circle, draw an arrow to the right until the graph ends. This shows that y could be any of these numbers greater than -9, too.

I attached an example of a filled in number line for a different problem so you could see what it looks like. I hope this helps!

y-3-(-12)≥0

y ≥ -9

y + 9.000 ≥ 0

y ≥ -9

I hope this helps!

How many times greater is 70 million than 7 million
Dahasolnce [82]

For this case we have the following expressions:

70,000,000

7,000,000

If we divide the first expression by the second we have:

\frac {70,000,000} {7,000,000} = 10

Thus, we have that the first expression is 10 times greater than the second expression.

Answer:

70,000,000 is 10 times greater than 7,000,000

Im doing decimals greatest to least and i need help with number 12 and 13
erma4kov [3.2K]

(I know there isnt any real problem here to solve, but heres a tip on how to solve greatest to least with decimal problems)

1. Just because a number looks big, doesn't mean it is big

Example: 1.00000000000001 < 1.1

just look at the numbers ^ and dont just hastily read it over assuming that 1.1 is smaller because it "has less digits"

2. Negative numbers are... opposite. and they are less than positive numbers

-3.4 > -4.1

Why is this? Well, if you look on a line, with the point 0 in the middle, you can see that -3.4 is not as far away from 0 as -4.1 is. So the idea is to apply opposite logic for negative numbers

I hope these tips helped!! :D

The way it is written, none of them.

\dfrac{am}{an} =\dfrac{m}{n}

The "a"s cancel out.
