How do u solve this for g: 2g+9≥-5g-12???? plz show all work
mart [117]
Hello! To solve this equation, first, add 5g to both sides. There are many instances where you would add, but because -5g is negative, you add. You do this to cancel that out, and get the integer without the variable on the right by itself. When you do this, you get 7g + 9 >= -12. Now, subtract 9 from both sides to get the 7g by itself. After that, you get 7g >= -21. Now, divide each side by 7 to isolate the variable. -21/7 is -3. There. g >= -3.

Iff a/b is a rational number, what does b have to equal in order for a/b to also be an integer
postnew [5]

You're thinking b=1 will always give an integer, certainly true.

Then you think b=-1 will also always give an integer, so

Answer: ±1

Then you remember that a/b may not be a reduced fraction, so other bs beside the unit make give integers.   The condition for an integer is

b | a

read 'b divides a'  meaning a is a multiple of b.

Then you realize that a and b might not even b integers themselves.

Let's say the above answer is correct with the additional criteria that a and b are integers with no common factors.

Suppose
Anastaziya [24]

Answer:

<h3>0.2</h3>

Step-by-step explanation:

Given a linear function f(x) that varies at a constant rate of change 1.5 with respect to x, If x varies from x = 1.3 to x = 1.5, the to get the amount by which x change by, we will use the expression;

Δx = x₂-x₁

x₂  is the final value of x

x₁ is the initial value of x

Given x₁ = 1.3 and x₂ = 1.5

Substitute the values in the formula above;

Δx = x₂-x₁

Δx = 1.5 - 1.3

Δx = 0.2

Hence the value of x change by 0.2
